I can really appreciate the effort you went to here. I've been running ATs on my T5 for about 2.5 years, and whilst I've generally enjoyed my time with them I would like to add something else that rarely gets mentioned - and that is how bad the grip is in certain conditions. On cold and wet roads they are horrendous, and on black ice - or in temperatures where black ice is imminent - they are borderline unusable. I've had a couple of experiences of the latter, and recently when setting off early one morning in the Cairngorms, the van really struggled to gain traction at all, when my friend in his T5 running bag daft 20" things with rubber bands around them didn't even realise it was icey. Apologies if that's already been mentioned - just wanted to add my two-penneth, and also wanted to learn if anybody else had experienced the same.
Oh, and I immediately checked my pressures after the Cairngorm incident, and they were at the recommended pressures.
Well you answered my suggestion at the end there with the pressures.
Not had icey experiences yet. But thanks. I’ll strap in ha ha
Makes sense - one additional thing to mention that people should also adjust service intervals by 10% as well to match real use.
👍🏻
Finally, someone else has seen the light. Been saying this for years. Me and my mate have the same vans. I have bigger tyres and he has Standard. Do a Long Haul Trip and its quite surprising the difference. Yes it’s effectively clocking my van, so what, works in my favour. Do I get Stuck in Snow where i live? No. How about mud? No. Can I drive to the Alps for skiing without purchasing winter tires? Yes. Speedo reads bang on now too.
Awesome. Thanks for your comment👍🏻
Nice one buddy…great take on the tyre size issues. 👏🏼 inny 👍🏻
Cheers mate. Yes inny 👍🏻
Now that was a good video, Thanks
Outy for me 👍 😉😉
Ooh. Outy
Great video. Interested to hear what you learn about compensating for the larger wheels and tyres on the t6 computer.
Inny.
Nice one. Thanks.
One benefit of running larger tyres is the lack of punctures. I had BFG K02'S on my work crafter for around 15,000 miles and not one puncture. I go to a recycling plant about every 2 weeks so theirs nails etc on the floor and the meaty ruggedness of the tyres deflected them all haha. Plus they look tough 💪
Ah man. You’re right. I’m all for it. 👍🏻 regardless of noise Speedo mileage and mpg. It’s the WAY
I’m glad I wasn’t sat next to you in the van for 100 miles

Top job & experiment :)
Cheers you
My VW camper had been lowered and fitted with 20" wheels before l purchased it 5 years ago oh it looked lovely but after several cracked alloy wheels broken rear springs 3 new front splitters on the spoiler it was time to get the van lifted the relief of not worrying about pot holes and being forced into crapy passing places and getting into most park ups makes traveling so much more enjoyable and thanks to good advice l didnt buy the BF Goodrich tyres so l havent noticed any noise increase so at the moment l love the new upgrade
Honestly mate. I had a t5 on air. With stretched tyres etc. brought me nothing but heartache.
When l see a lowered VW now l just have a little chuckle:)....

@@project-overland 👍🏻 thanks for your support pal 👍🏻👍🏻
Great research and validation. Got the same tyres and wheels on and my gut was MPG was about the same as before… I find 60mph is a decent sweet spot between MPG / wind noise over the roof and getting that first beer at camp on 😅
Hadn’t considered the mileage also being out though. But at 150k and only 10k on BFGs so far I’m not worried.
None of the cons out way the pros for sure. Got to add drama in the intro. Ha
@@urbanarkoverland Deffo. And having made it out of the mud bath that was Nash Oakland a few weeks ago the BFGs proved their worth.

@@VanFamilyAdventures see you have a channel. Will check it out later 👍🏻
Some very interesting information

I’ve put 275/35/20’s on my T5 and using a app based gps setup, the Speedo is now spot on. They aren’t accurate on factory setup so kinda balances out your argument. On our motorhome I’ve put the same size Bf Goodrich ko2’s and tbh the noise and economy difference is negligible. Better on a wet field tho 😉💪🏽
That’s assuming it’s out the other way. What if it’s out the same way?!!!
On the standard 16” the T5 was showing 60 when on the gps was doing 55. 😉
@@stevebennett6727 woah
Useful big wheel exercise and well explained. Further hidden side effects and food for thought when thinking of braking and stopping distance.
The rolling radius variable is used in the brake design calculations. With larger tyres the rolling radius is increased so thus the braking efficiency decreases. If you are recording a 10% difference in the distance travelled versus what the speedo says, how does such a 10% impact on the story of braking efficiency?
It is my opinion that such a 10% in the braking efficiency could make some vehicles not suitable for road use. People do not usually know the braking efficiency impact of increased tire size if they do not re-run the braking calculations with the revised rolling radius variable included in the formula. To do so with the new variable included might indicate that the calculations show a fail by having the efficiency falling outside acceptable design criteria.
Thus stopping distances in a vehicle with larger tyres fitted could be increased by 10 to 20% or even more depending on the size of tyres fitted. Alternatively the pay load that the vehicle can carry may need to be reduced by a similar percentage or more so to get back to acceptable braking efficiency and roadworthiness.
Not sure if I’m on board with this.
The brake size is still the break size. And if anything. More rubber touching the surface of the road is an advantage no? I slammed in the other day in an almost emergency stop and believe me. My head nearly rolled off
@@urbanarkoverland He is correct, larger diameter means more leverage toward the centre of the wheel and more braking power to stop the vehicle as quick. Not noticeable in normal driving as the van will be braked based on a fully loaded van and trailer limit but get close to those limits or do long alpine descents and it will generate more heat and need more force to stop. Although your van is not actually 10% out its more like 5% out as all road vehicles come with around a 5% over read on the speedo so manufacturers can not be blame is tyre/wheel sizes get changed and you pick up a ticket and to allow for tolerances. If you had a van on standard sizes and clocked the speed using a gps device/App on your phone you would see a stock sized vehicle would be showing 5% more than the gps unit. So in reality you are only 5% out ish.
Another great video 👍🏻. Inny for me
Yes lad
Thank you for this. I was wondering about the impact mpg and milage would be just a few days ago. And your video pops up and answers my questions.
Excellent 👍🏻
Great video, you just show exactly what I am thinking in do and all all the questions I had, I gonna contact some car tunning places because I want bigger wheels in my touareg but I want the car to work accordingly with the mod...
Thanks again and if you manage to do the ECU correction, post a video of it.
I went to vw to do it. Made a video on it. But….. found someone that knows better 👍🏻
@@urbanarkoverland I just contacted a ECU motorbike mapper asking them if the ECU can be edited to recognise whatever size wheels, I have done some engine modification in bikes and every time I done something, I reset the ECU and run the bike as harsh as possible so the ECU remap and relearn the new valance, obviously this is just a numeric value somewhere...
@@RicardoCerveraBlanco it can be done mate. Hold that thought for part 3
@@urbanarkoverland Awesome, I been chating with Xtool to get a scan tool and they will let me know which scanning tool does the wheel size adjustment...
@@urbanarkoverland Hey man, I know you still working things out, I just find out a few things, apparently there is a module that gets plugged inline to the ECU to correct this BUT I also find out something more critical, the speed sensors are in each wheel as part of the ABS so the ABS knows the speed of each wheel and applies the right breakage in relation to the speed, that means the bigger the wheel the longer the breaking distance would be "or less aggressive" and the smaller the wheel the shorter breaking distance would be "or more aggressive".
I went from 235/55r17 to KO2 225/65r17 and Speedo was spot on by gps. Meaning I can pass a camera at 70 but no more.
Excellent. 👍🏻
A few years ago i worked at a VW commercial dealer and they sold a camprer T6 to some customers who fitted banded steels with swamper tyres, somehow or other they got the tyre sizes wrong and the rear tyres rubbed the plastic wheel arch liners not only that it also split the inner wheel arch away from the outer panel so the rear quarter panels were all floppy
They must have been extreme.
I replaced my 15" 190 wheels on my slk200(the weakest) with 17" 245 rear 240 front (the biggest allowed on Mercedes R170). I didn't noticed any higher consumption or lack of power. I did the full tank, refill after 100 km method. Also my speedometer was spot on with waze and TomTom satellite speed. So, if all goes well, I'll get a Transporter and put bigger wheels on it.
Cool. I have discount codes everywhere nowadays 🥰
Vehicles must not under state the speed therefore, in OEM trim they over state the speed and therefore claim higher fuel economy than they actually achieve.
Slightly oversized tyres will make the Speedo and fuel economy more accurate.
I've done a similar experiment using Strava for both accurate distance covered and speedo Vs actual speed.
My previous vehicle was on the dot after bigger tyres and my current still overstates speed by 1.5%
Yes. But this has clearly made mine 10 percent out. And today I was filming part 2. So i can confirm that the Speedo is EXACTLY 10 percent out now. Regardless of how true it once was.
Yea different makes and models are different
Hi. I’ve often wondered about this. I have a T6.1 and replaced one set of non standard alloys with all terrain wheels (fuel zephyrs) and tyres (general grabbers - I’m an inny btw). I also had the computer changed but more for the tpsm than the wheel setup - but I’m assuming this has also rectified the speedo/mpg/odometer stuff also. Thoughts? I think you said that the computer couldn’t be done but the guys at Bognor Motors fitted the wheels & tyres (bought from Transporter HQ) and updated the tyre spec on the head unit.
I am sat I. My van and literally just saw what you mean. Winter tyres. Wow. That’s cool.
Just researched this. Only thing they can do in the head unit is set an alarm. At a certain speed. It has no calibration properties.
@@urbanarkoverland I believe they added the tyre size as it isn’t standard, so I’m assuming with the correct tyre size this now calibrates the speedo etc. they would have needed to do this as I have tyre pressure sensors on and they would freak out on a different size wheel.
@@nicktarling6099 ah. That’s the tyre pressure sensors.

I'd love to put decent bigger wheels and tyres on my van but I haven't got £1500, and it would use 50% (conservative estimate) of my self build budget plus I'd rather keep my better mpg. I'd rather spend it on solar and decent batteries all day long. Will have to make do with my standard steel wheels, they'll be fine for my urban van life and maybe a pair of £60 traction boards for emergencies. If my budget wasn't so tight I'd love some decent wheels and tyres. Enjoyed your video though and thanks for the insight. 👍
Ah mate. Keep ya eye out on Facebook market. Always some deals on there 👍🏻
I get 740 mile to the tank on my 20 year old t5 filled up in Watford and got 50 mile south of Burgos with a motorbike in the back and tools .
Good going
What is the overall difference in height for the van with this added ride height? May affect access to certain height limited car parks…
Not sure how much height it adds. Depends on tire size I guess.
I’ve also had a 2 inch lift kit and can still get in multi story car parks
Awesome. Thinking this through....are your new wheels and tyres 10% larger in terms of overall diameter or circumference over the standard wheels and tyres? Just wondered if that size difference matches the amount the MPG calculation is out? If it does then it would allow people to calculate their true MPG without having to drive 100 miles and do a brim to brim calculation 🤔
Wait for part 2 👍🏻

Thanks for watching.
@@urbanarkoverland Ha, yeah it’s amazing until it’s not and takes you down some road that keeps getting smaller and thinner by the meter and you have to reverse your massive van all the way out again. 😂 never had that problem since switching to waze 👍

Interesting idea and very well made mate. Great video 👏🏻👏🏻
Cheers you. 👍🏻
Let’s be honest it’s all about making the van look like a cool 4wd truck. People fit big tyres and wheels to their transit van for the same reason boy racers put a spoiler on their mum’s old 3 door clio.
Ha ha. Defo
Okay, I didn't quite understand this, does it use more fuel on bigger tires?
It takes you further for each spin, that I understand, and unless you hook your cars computer up, and let it know that you have bigger wheels, it will count the mileages driven wrong.
So it doesn't make more sound (and why would it, that's the build of the tire, not the size which accounts for noise: road tire, vs offroad tire)
It takes you further for each mile you drive, which should be a good thing, unless you are buying a used car with large tires, and it hasn't been calculated right, so it might have more milage than it shows.
But when it takes you further for each mile, shouldn't that mean that you save fuel?
Or is it because the larger tires makes it run "harder" so it uses more? 🤔
Hi. Firstly. They are noisier. But after insulating the van. I’m not bothered by it.
They definitely do reduce mpg. Because it takes the van more effort to travel. More tyre touching the road is a higher resistance.
But the point is. When you fit big wheels and tyre. You will see in the computer that your mpg will reduce dramatically. Point being is that it’s not quite as bad as the computer says it is.
Great video but what is the new tyre size on the van?
On the transporter?
I've just calculated it to 41.44 mpg. 10.97litres ÷ 4.546 = 2.413gallons consumed. 100 miles ÷ 2.413gallons = 41.44miles per gallon. Assuming you filled to first click originally and again after journey. What percentage of your miles was motorway?
Ha ha ha. Hats off to ya mate. For working that out….. but you must have skipped the video. Mpg
Was over 98 miles as fuel station was 1 mile away from home. But great effort pal.
Thanks
I’ve got a 2020 vw crafter pickup with 245/65/17 bf ko2 I only get 275 miles to a tank full it worked out 20.5mpg. most of the time it’s loaded up. I was completely shocked how rubbish it is!
Yeah. That depends on how you drive it and how loaded up.
I get 22 out of this van on the school run days.
What about the shift pattern....my Jeep Patriot 2.0 crd 6 speed manual runs at lower RPM....
Not lower than a smaller tyre it won’t
Hi how much was your overall diameter increase, great beard by the way im sat here with my patchy best effort haha
Afraid I never measured.
Cheers regarding beard ha. Keep at it.
i did this exact test when i put larger tyres my T6.1 and found when traveling 10km the odometer would only read 8.2km. 😂makes it hard to calculate consumption
Nightmare huh. Stay tuned for part 2
Interesting, good video!
Greg's coffee = 🤮🤧
Defo. Ha
I’m with you, I thought it was a euro thang
Euro??
My VW T4 has 18" RS4 alloys on it and has always been slightly off with distance and speed. To counter and know what speeds I am actually doing I trust the sat nav speed, used to be TomTom, now use Waze. Different was minimal, tbh but enough to notice or be on the wrong side of a speed camera.
Yep exactly.
The benefits outweigh the negatives. For every extra inch of diameter you are getting three extra inches of travel per rotation of the hub therefore better mpg at the cost of slower pull away. You will get even better mpg if you use a satnav as a Speedo to make sure you hit the sweet spot for engine efficiency. This gets round the issue of the Speedo reading low. They also last longer and don't seem to get punctures. Can cause issues with wheel bearings as the bigger you go the harder they are to balance.use with steel wheels for max strength off road or hitting pot holes. They look great, last ages and you are less likely to get stuck leaving a campsite or off road park up. Maybe a follow up video is needed with the satnav to get max economy?
Oh mate. I’m totally on board. And what’s the other option. Go low…… never again.
You are assuming the VW engineers have not done the performance check with wheel size. I get all the advantages of rolling capability offroad, but when I put my T5 2.5tdi in 6th on the highway it does a lazy idle. I don't think larger wheels will improve economy, except downhill, as the physics say you are moving the same mass with the same air resistance. If there were such gains to be had VW would introduce a 7th gear. Forget Satnav, you need full access to the EMS to input the new wheel diameter and let it calculate the correct diagnostic outputs to the speedo / odometer and provide the correct fuel consumption readings. Problem is many speedos do not give the true velocity as manufacturers put a safety margin to ensure their tech is not getting people pulled over for speeding. This can be easily checked with your local roadside radar speed signs that do provide accurate readings of vehicle speed.
@@antc5010 Hi Ant,
I'm sure the engineers have, they would have settled on a real world compromise or we would all be driving around on huge wheels if fuel economy was the only concern. Larger wheels would be like having an extra gear but would reduce your pull away and hill climbing ability but will give a longer distance travelled per rotation of the drive shaft which is constant (shaft rotation=engine revs+gear+speed) at any given speed, bigger wheel/tyre diameter=longer distance travelled per rotation. As for the seventh gear some auto boxes have seven or more gears. Newer versions of my van (manual) have six speeds but mine only has five, maybe more gear ratios will be more common in the future. GPS on a Satnav is the easiest way to measure speed, it works to measure velocity of any moving object, car, van, boat or plane. Also my Defender (1993) doesn't have an EMS so I need the GPS/Satnav to keep me within the law as an indicated 30mph is in fact 32mph on the GPS were as with the correct size wheels and tyres it would be 28mph on the GPS, this is for the reason you correctly stated that the manufacturers put in a safety margin with the speedo. Usually they most accurate at around 30mph. Interestingly with the Defender with oversize tyres an indicated 40mph is actually 45mph!! so the speedo is under reading as the speed increases.
On an HGV. It is calibrated to56mph. When the tread starts to wear out the speed is higher. From this, the larger the wheels it will show a slower speed. The smaller the wheels it will show an increased speed.
To get the speed calibrated you could go to an HGV testing station and ask if they could put your vehicle on a rolling road to set the speed limits😊
Yes. That’s what I evaluated in the video 👍🏻
It was the last bit I thought you may have been interested in. Seeing if you could have your speed recalibrated, with influence an HGV garage may do it for you😀 you never know
@@Homesteader40 I’ve had it done mate. Just not made that video yet. By a guy that actually knows vw’s. As opposed to vw themselves ha

Nobody mentions these BFG AT tyres on horrendous on a wet road? Like holes in hedges horrendous.
These ones. The cross terrains? Or the all terrains?
@@urbanarkoverland sorry, the ATs, I see loads of campers with BFG AT on, I have them on my Nissan Navara and they are really dangerous on a wet road especially in the summer when the roads are dry then get some rain, like Bambi on ice!
@@TimZ750 think the cross terrain should be better?
In 20 years of experience there are many cons one pro …the pro .looks cool 🫤 changing tyre size there is a tolerance . But yes with in years it can make a slight or major difference on the miles . Depending on the van here are what people don’t see. It’s a Van and really has to have XL tyres if fitting all terrains there are not many XL , they are stiffer side walls so harder ride on the recommended psi ( tyre pressure) it will affect the MPG . I’ve had as much as 5mpg difference . And run 5 psi lower to make it a bit softer . Also it will also if they are all terrains or similar put extra stress on the wheel bearings and drive shafts . But it’s never that simple that’s a guide from my experience, I fit a fraction bigger to give a little more rubber between the wheel and tarmac but my Speedo is only a fraction out it certainly won’t make 9 thousand miles in 100 thousand . I’ve owned 4 vans now 3 had completely the wrong size two registering 5mph high. So 50mph I was doing 45 , one was a t4 I guess made to look cool , my current van was strangely on even wrong size wheels as well as tyres and way to small in my opinion dangerous. , on another note my mini also had tyres to small on it .
Can’t agree that only has one pro. Even you just said. More tyre on the road. By definition they are better in a different terrain. Harsher conditions. Wet,snow, gravel etc. Also, very rarely get a puncture. I never have.
I had 19 inch Bentley continental wheels with a diamond cut edge in rubber bands. So parking I had to think twice. Have I g such a. Large side wall. That’s no issue. I’m not saying it’s right. But it’s definitely not wrong.
@@urbanarkoverland there probably isn’t one answer as so many variables, even countries and like you say road surface, but I will say I have been shocked over the years what vehicles have got where there shouldn’t and had a 4x4 get from A-B on all terrains and I was spin on Muds different vehicles differently traction control systems different gearing . It’s never simple lol

Well they do say that all vehicles have a discrepancy. That’s why you will never get done doing 54 in a 50 etc. but if it’s out already. And then you change wheels. It will be really out
@@urbanarkoverland is it worth having a separate satnav & checking how far out the new bigger wheels are & just drive to the satnav speed
@@yanmills find part 2 👍🏻
We own a Tachograph station and when HGV change the wheels it can make a big difference yes the Speedo is out and the mileage is out and sorry to say yes the fuel consumption will be out VW are the only company that you can change to onboard computer on some of the models the other thing that people should remember that you need the correct wheels and tyres for the load rating of the vehicle the alloys might look like they fit but are they the correct load rate for your vehicle
Yep. You are right all across that message.
Load rating is massively underestimated. And actual approved ratings too. TUV I think it is.
Just had it sorted this week actually. The calibration that is
I have big BFG KO2 tyres on my T6 and they corrected the mph to be correct. I have tested the speedo against a GPS speedometer and it is spot on. Car speedos can be 10% out from new, but they always over report speed. Legally they can show 110% + 6.25 mph.
Yeah I didn’t wanna dove too deep. Or make vid too long. A mate of mine put big wheels and tyres on. His original speedo must have been out the other way. He thinks his is joe spot on. (Defender) 👍🏻
I will get one of those gps. And test it. And see if I can get it calibrated. Did you go to vw?
@@urbanarkoverland anyone running ODIS (dealer tool) will be able to change the tyre size setting, I also suspect it’s possible to change this via the VCDS tool.
If using VCDS I would advise taking a capture of all control units coding and adaptations before changing anything, that way it’s simple to restore original values if anything gets messed up…we see messed up coding all the time where people change loads of stuff and mess it up and then don’t know how to put it back because they have no reference to work to.
@@picotrain5959 excellent. Thanks mate.
So if you claim back you driving by miles travelled and trip computer reading… that means for a new business, you will always short change yourself, by 10% £/miles… business miles for HMRC 1st year/12months during startup is £0.45. So for 100miles per week you loose £45 - about £2340 per year loss…. I think…
This is interesting … great video
I don’t know the ins and outs of the hmrc. But if you did 100 miles at £0.45. You would lose 10 percent. £4.50. The £45 is the whole amount
@@urbanarkoverland tax claimed back for businesses hmrc/taxman Currently, HMRC mileage rates are set at 45p per mile for the first 10,000 miles for cars and vans. After 10,000 miles, the amount that businesses can claim back drops to 25p per mile. So…. Employee travels 12,000 business miles in their car/van (per yr)- the approved HMRC amount for the year would be £5,000 (10,000 x 45p plus 2,000 x 25p) meaning Big Wheels (-10%) make that 10,800mls. So you loose 20% x 1200 of claimable tax… makes one think of the cost of looking cool 😎
Why do the UK buy litres of fuel but work out Miles per gallon?
Because we are stuck in our ways.
Outy all the way, I can't imagine the hazzle of trying to read the text on the inside..
The text is on both side. Inny outy is referring to the fact that bfgoodrich is highlighted in white on one side. Apart from that they are the same.
I really do not know why people are so surprised about this. In the day of analogue speedos and tachs, large wheels always resulted in lower speedo readings for a given RPM, and consequently the odometer ticked over slower. Now with drive by wire, why would this change as the relevant sensors for rpm, speed and mileage all rely on output rotations either at the crank, transmission or wheels (ABS)?
Yeah. But the point is. It makes the mpg SEEM worse than it is. We all know it affects the Speedo. But it’s the knock on affect.
@@urbanarkoverland Well that's a given! For the sake of argument, let's say fuel economy doesn't change much with increased wheel size, but the distance recorded is significantly less. It goes without saying that fuel economy will look worse.
@@antc5010 perhaps we aren’t all that smart
@@urbanarkoverland Not trying to knock your video, as you've provided awesome info for those who haven't done the thinking. It's just that I've tried different wheel sizes since my days playing around with Minis when I was a kid. There was little tech in those machines to get distracted with, so you had to work it out for yourself.
Mate…u haven’t been driving long distance before u went off for the 100mile run..u prob been driving around the town etc,,then u went off for 100mile and that calculated the previous use as well …that’s why your mpg was less then when u calculate it on line or paper without taking into consideration your previous lpg u been doing around town etc…this is combine mpg the 36..mpg
My tyres makes me go slower..speedo says 50 but I acutely doing 47/46
No. I zeroed the mpg. Before that trip. It’s not about how much mpg I got. It’s about what the computer says. And what I actually achieved. That is explained in the video.
😎👍
👍🏻🤪
It gets worse it will cause excessive wear to the steering brakes suspension clutch and gearbox. All of which where not designed for different sized rolling radius of bigger wheels.
Although no one has ever seemed to report this actually being an issue.
But your has done LESS miles not 10% more; which makes sense because the 17' tyres are turning less often than 16" tyres would. Why not use the Sat Nav to measure the distance? Sat Nav is very accurate and probably far more accurate than Google maps. And of course the MPG will be improved because the tyres are turning less to cover the same mileage.
The van is doing 10% more miles than what is being recorded.
just check your speedo as you go past a road sign that tells you what speed your doing
🙈
Sorry but that isn’t accurate, when the local authority installs the driver information signs, they can program them to read up to 10% higher (or lower) than detected speeds, or give the exact amount, it depends on who, in the highways (or road safety) team is given the task.
Lets not forget braking distance, especially on wet road..
Forget what about it. What’s your thoughts?better or worse?
@@urbanarkoverland On wed road I find braking really bad, almost slides like a sledge. I guess it must be related to the surface contact area between the tyres and the road surfaces ..
@@doublecoolgamer8490 surface area is greater therefore should be better 👍🏻
This is why I will never buy a van someone else has messed about with , you can't trust the mileage.
👍🏻🤪
Bigger tires don’t fall into as many holes….less bumpy ride! Outty….
Ye. Pothole Britain.
and the haldex has to work harder and and can get damaged depending on how you drive
Never heard that
Bud, you don’t order the tyres with the writing on the side you want, the tyres can used either way round 😂
Yes I know ha ha ha ah. But that’s how they come. And didn’t wanna bother go getting them swapped. And pay. So I left it.
Said that in another take. But cut it. 👍🏻
@@urbanarkoverland ohhh you ordered the wheels with the tyres already on, fair enough 👍🏼. You got me intrigued now, I’m out in my van later and I’ve got a GPS speedo on my phone.
@@Jarv263 ye. In fact. I ordered them in. But they came out. Yeah wheels and tyres fitted package.
Do let me know ya results 👍🏻
No matter wat would not fit these wheels wat so ever thieves lov them£😋
Does that still happen?
I’d be more concerned about speeding through speed cameras and police vans without realising it!
Exactly mate
@@urbanarkoverland I spoke to a guy with big tyres on his van and he says he goes through a new clutch every 2yrs. Either he’s buying cheap clutch kits or he’s lying 😂
@@Legend-wu7pj I have NEVER heard that.
Not saying it isn’t true. Well I kind of am ha. His vehicle must be very underpowered
@@urbanarkoverland yeah I thought he was chatting crap, unless he’s ragging it everywhere then “maybe”
Inny 100%
For sure.
Increasing unsprung weight on any vehicle decreases handling
Handling in what sense? For its purpose…. Off roading. It increases handling and agility.
Can’t you use your iPhone to get the correct speed and then compare the difference…
👍🏻
Mileage means absolutely nothing to me and shouldn't mean anything to other people also. Example: Two people....myself (middle-aged) and a young guy both living in a big city. I have a contract working on farms outside of the city for 5 years. The young guy is at university and he and his friends only drive around the city. So most of my driving is done on the highway, driving at a constant speed and remain in 5th gear and hardly using my break pedal, clutch pedal or steering and needless to say not much tire-wear etc. I think you start to see where I am going with this. The young guy drives shorter distances than me but have to constantly use his brakes and gears and steering by turning constantly etc. Then because I am older and love my vehicle, I make sure that I change my oil regularly between 5 and 10 000 kms and I do it myself as I can tell of horror experiences I had with the actual agent's workshops in the past. Not only engine oil but also changing my gearbox oil, and radiater coolant liquid etc. I check my tire pressure regularly and change light bulbs and replace the brake pads as soon as it is needed. Of course I would then also clean and wash my car more regularly.
But because of my contract after 5 years my car has much more mileage than the young guy's car.....so which car would you buy???? Mileage means absolutely nothing!!!!!
I understand your mentality. But it doesn’t mean nothing. A van that has done 10k hasn’t been on the road long enough to have missed any vital services.
If you buy a van that has done 80k and hasn’t had the clutch and flywheel cambelt and pump doing. You know that’s needed. So I understand you saying a well maintained high mileage is better than a in maintained low mileage.
But between buying a van with 10k off of an idiot and 100k off of someone that rigorously maintains. I know what I’m buying.
Also. Regardless of how well it’s kept. Somethings naturally age due to miles on the road.
So what you're saying
If i put tiny wheels on my van I'll get amazing mpg 😂
It will improve.
But the message is….. the reading is altered. Not the actual mpg. It’s a false reading. Bigger does reduce mpg. Road resistance etc. but it isn’t as bad as the computer says.
I get 42mpg with 20s on, Speedo is more accurate, ride is fine, traction no issues and even gets the old women wet when they see them
Is your TH-cam name Floyd related?
@@urbanarkoverland I’d love to join in on the joke
@@comfortablynumb8832 your name is comfortablynumb. A famous pink Floyd sing. I’m a Floyd fan. Obviously not related.

You don't "INSTALL" wheels on a vehicle you "FIT" them!
Install. Verb. Place or fix in position ready for use.
Idiot
@@urbanarkoverland ~ Fit Fool Fit Fitted Fitting Fits Fitters Fit... Fitting & Balancing!!!
Think you got this the wrong way round. Big tyres will show less miles than actual miles travelled…….
Yes. Which is exactly what the whole video says. Your van will have more miles than it says.
@@urbanarkoverland maybe I miss heard you, I had the impression at the start of the video you were saying the odometer would show the van had done more miles than it had actually done in reality.
@@eckythump6429 no mate. If the van has 45k on the clock. Truth is. It’s done closer to 50 🥹
@@urbanarkoverland bigger tyres are also increasing your gearing, better for MPG depending on how big you go, gearing not so good for off-road especially if you don’t have low range transfer case (like my Crafter).
@@urbanarkoverland yes so you van will look lower mileage when you come to sell it so in effect the buyer would get humped.
This is completely wrong sorry the mileage would be lower you literally explained it yourself
Yes. And I explained it that the mileage is lower. Drive 100. Computer says 90. I literally said that.
Check yaself before you reach out and complain.
Hence the expression. Basically clicking ya van.
I don't get how it would devalue the van though
@@MATTCHAR1 because if people see van for sale with bfg’s on and it has 90k on the clock. They could realise it’s actually 100k.
@urbanarkoverland the tyres would have done more mileage but the engine and components like cam belts would still be relevant to the clocks same as servicing
