My Jeep Grand Cherokee Laredo with 318 all time all wheel drive and did 0-60 in 5 and 6 seconds all the time and the wheels were the stock aluminum with 235/75 tires so it's no surprise your truck hit that time !
That’s a negligible difference in both economy and acceleration, while achieving far superior performance off-road. Great job.
Call me basic, but I love the stock steel wheels on these XL trucks, especially with the bigger tire. Clean, simple and functional.
Exactly. I hope he continues with the stock wheels.
Jay: yeah the stock steel is what I use, except I got rid of the plastic centers aka " hubcaps " about 30 minutes after I got the truck also something happened to the stock muffler after a few cuts it fell off so I installed a "FLOWMASTER " which makes my 5.0 sound great
I've been running this same set up myself since 2014 when I bought my XL new. Never cared about the fuel mileage and I love the look and capability.
Yeah I have done this to more trucks than I can remember, and I always see a 1.5 to 2.5 MPG decrease with slightly larger, heavier tires. BUT, the benefit is that I haven't had a flat tire in decades on aftermarket tires, whereas the factory garbage will get sidewall damage easily.
My favorite TFL presenter in my favorite TFL recurring vehicle. Lift and tires look great and are not "too much". I would absolutely love to own this practical and capable truck.
Andre I think your truck looks and is perfect. The stance and tires is on the money. Can't wait to see the improvement off road.
That came out pretty rad Andre! (Appearance, Utility, and efficiency). Looks beefier with the new tires, can still do everything it could before and didn’t loose too much fuel efficiency. I’d call that a win!
As I've watched TFL over the years . I only find that I enjoy watching Andre. It just seems he comes across more genuine and personable. Although all of TFL content is great.
Keep up the good work Andre!
The bigger tires and leveling kit, really changed the look of the truck. It looks great!
Don’t forget to reset the aim of your headlights since you leveled the truck.
and not to mention if you have a Ford with a few more options the lane keeping feature will no longer be able to work or be recalibrated for a level truck
@@ubeuonly it’s very clear you don’t have a clue what you’re talking about.
@@BiggMo those halogen on his truck are
you don’t have to do that but if you don’t do it you’ll be blinding people
That's only for heavily loaded trucks where it actually changes the angle of the front. A 2-4" lift doesn't change the angle.
Hey Andre, love these videos. I got my PB Crew Cab XL 6.5ft bed, I put a leveling kit from Rough Country too but bought the shock and strut assembly and rear shocks. Then upgraded the stock rims to Ford FX4 18in rims, up from stock 17ins. I was able to fit 295/70 R18 with no rub. Looks great and my avg mpg is about the what you showed on the video. Love this truck!
This is an interesting and informative video. Thanks Andre and TFL. I have a 2014 F 150 4x4 Supercab ( extended) with the naturally aspirated 3.7 V-6 rated at about 300 H.P. and similar torque. It has the 3.73 axle ratio. The truck also has a duel fuel system with CNG provided by Altech-Eco as a Ford option. The 15 gallon CNG tank is cross mounted in the bed and weighs hundreds of pounds. My gasoline tank holds 36 gallons. Stock tires were 235 75 17 and I was running 265 70 17 Goodyear Wranglers all season tires. I switched to Bridgestone 285 70 17 10 ply E rated Dueler Revo 3 A/T tires on stock steel wheels. I added a 1.5" level lift and Air-Lift air bags for the rear suspension. I also added a Roush low restriction air cleaner .Before I added options I was getting close to 22 mpg on a good day, level road, 70 mph , 2,000 rpm. The lift and bigger tires dropped the mpg by about 3 mpg. I noticed it took more work for the truck to turn the bigger tires when accelerating but once at 70 or so it was fine. The lift seemed to create more drag at the front and I felt the wind pushing it around more. I believe that contributed to the loss of mpg. My tires can take up to 80 psi and I keep about 55 psi for normal driving without a load. I like the E rated 10 ply for stiffer handling, especially with a load. When I air up the rear air bags it brings the rear end up a good inch or two and gives more slope downward to the front end, decreasing wind drag and increasing mpg. I love the woosshing sound of the Roush air cleaner and I believe it helps the mpg a tad, Plus the filter can be cleaned by hand. I also have a hard tonneau cover and that likely helps mpg a bit. My conclusion: the low restriction air cleaner helps. The rear air bags allow me to lift the rear and lower the front reducing air drag. The front puck level lift pokes the nose up a bit. I would not get anything taller than 1.5". The E rated Bridgestones are a nice all terrain tire but their bigger size and width slows the truck down a bit. These tires are about 33" and I wouldn't put anything wider with the stock suspension for adequate front end clearance. The bigger tires throws the speedometer off, especially at higher speeds. So, my mpg is actually better than the truck indicates. Still the truck has to work a bit harder and downshifts more when accelerating hard. I'm basically happy with all I've done. Keeping some rake in the front end helps mpg, noticeably , but I wouldn't want to go back to factory rake which is about 2". I don't like that look. Returning to a more stock type highway tire of 265 70 or 75 x 17 would improve mpg but I like the Revos for snow and off road use. Btw, I also love having the CNG option. CNG is cheaper at the pump and it gets the same mpg and performs as well as gasoline. The tank does take up space in the bed though and adds some weight. I love my Ford truck and not having a turbo doesn't bother me much. Andre's hybrid with turbo combination would feel powerful, no doubt, and gets better mpg than I do. Oh well, these are trucks, not Teslas. Happy trails!
I gotta say it looks great. Andre's F-150 now looks proper!
Love the look of this truck. Understated, with steel wheels, nice tires, a leveling kit and no pretend road-warrior stuff. Perfect!
If I were to ever buy a new truck, this would be the truck I'd get. Great video Andrey. It's funny how different it looks with the lift and new tires. It turned out great and I was surprised how little it affected the mpg.
I'd stay away from the new F-150 because they've changed the startup chime and it's very annoying. So, until Ford changes the new startup chime back to the old one, I will stick to the 2009 F-150 (or 2010 F-250).
@@brianlee9233 that’s a very serious point you bring to the discussion
OMH...I have all kinds of reasons to not buy Ford, but this Trumps, dare I say Bidens everything. No Fords!!,
@@dansherwood9851 - Too bad, you are missing out!!
@@dansherwood9851 Not sure how politics enters into the discussion. Seems that some people are obsessed.
I love the look without compromising what makes a truck a truck. It's a stud! Pleased to see the data didn't drop significantly. Really love the set up.
Great video and testing. I just picked up my '22 SuperCrew PowerBoost XLT last week - took almost a year to get here (owned it a total of 11 days as of this afternoon). I had the dealer put on the same leveling kit from RC and 34" tires, so I have no comparison to stock. That said, I'm super happy with the power and mileage so far. I love this truck.
We just bought a F-150 XLT Powerboost super crew and we love it. Unfortunately we cannot buy the XL in the Powerboost here in Canada like I was hoping for. Love the new mods and updates on stats. Please keep posting updates on the hybrid as you make more mods. Another great post thanks TFL truck.
That leveling kit and BFGs change the look of that truck to much it's amazing. I put a 2" quadratec spacer lift on my jeep JL and some 35"x11.5" Nitto Ridge Grapplers on my Jeep JL Sport and it just changed the look of the Jeep so much it's amazing.
I had my F-150 powerboost since Nov. 2021 so far no regrets . Love it . Did purchase extended warranty since it is 1st yr. w/new hybrid technology .
This trucks look REAL good with these new tires good job
Andre you definitely need to figure out how to program the truck for the larger tires. In the old days when I installed larger tires I had to change the plastic gear in the speedo cable. Now with everything computer controlled the vehicle needs to be updated to the larger size tire as it will effect the speedometer, odometer, shift points and other variables. It will also change your effective gearing in the axles.
Forscan might be able to do it on his truck. It depends if the PCM will allow the BCM to report a larger tire size. On my 2014 F150 I had to change the size in the BCM but also had to tweak PCM tune to accept the larger reported size from the BCM, otherwise it would throw a code and the PCM would ignore the BCM and default back to the factory size.
Forscan will do that. I have done this in my 2018, it did throw a code, so he'd have to reset it so the computer can learn the shifting points for the larger tires.
He may just take a trip to 5 Star for a tune and updates. They seem to have a good working relationship with them. Considering he just started modding the truck who knows what he will do next.
It’s still under factory warrantee, so a tune likely won’t happen before that runs out. I don’t think TFL has tuned any vehicles in the fleet which were still under factory warrantee.
@@TopKick818 They can't tune a 2021. Only Livernois can.
I saw similar results going from the 31" stock tires on my 2014 Sierra to 33" Discoverer AT3 4S tires. A little bit loss of efficiency but the year round performance of the all weather tires is easily worth the sacrifice. Plus they are very decent offroad. IMO all weather are a great choice for an all around tire. Especially if you don't have the room or funds for proper snow tires and your off roader is your daily driver.
I also put on 33s on my stock truck, with a 2 inch leveling kit.
I found the speedometer to be 2 mph less than actual and on a regular 107 mile trip my mileage reduced to 101 miles on the Odometer.
I saw a 0.5L/100km loss just in changing to bfg ko2 tires at the same size. And almost 1L/100km loss with a 2.5" level, 1" rear, (which I assume you had to fit 33s) on my '14. Would do it again in a heart beat, but I was astounded at the efficiency and power difference.
Yup. I'm running all weather tires too. But I shelled out the money for a flash tune. Fixes my speedo and tunes my truck for premium. Basically offsets the gearing and weight of the bigger tires.
I put these same tires on my F150 and they have been good tires but the main thing that I noted is that changing from the Michelin‘s that I had on there previously which were just all season tires these really gave me back the off-road capability that I was looking for out of the truck because I quite often take it off pavement for the work that I do and have to cruise around fields and down trails. These tires made it where win before I would’ve had to put it in four-wheel-drive to get out of a situation now with the new tires three out of four times I don’t need four-wheel-drive anymore.
Its amzing what a level and tires can do to the look of a truck! good looking truck andre!
I like the look a lot. It has a nice work truck look with REAL added utility and capability from the upgrades without taking a huge hit on economy
Between this and the comparison to the Tundra you've pretty much got me sold on the F-150 hybrid. Beautiful truck!!!
does the cars trip computer need to be reprogrammed to accommodate the larger diameter tires? .. e..g they cover more distance per rotation
Speedo will be off too.
I would say yes
Maybe. You can't assume it was perfectly accurate from the factory. You need to use a GPS app or Garmin and verify your mph at highway speed. Every vehicle I have owned has read 1-2 mph fast at 75. My current truck went from reading 2 mph fast at 80, to reading .5 mph slow with 34" tires.
Yes. It all needs to be recalibrated. I’m just starting this video and came here looking for this comment. If he didn’t recalibrate then this test is pointless.
@@nismomike3182 but if the speedometer is off then the miles will be off too.
Great video! Love the look of the bigger tires! Would have maybe liked to see upgraded wheels too, but definitely understand the cost savings and also steelies are pretty cool!
Truck looks great! still runs pretty nicely with the larger tires and being stock is impressive.
Im going to get a lot of crap for this comment, but this truck looks much better than any of the fancy higher trim trucks… and this new lift and the tires make it look like the best bang for buck everrrrrrrrr. Awesome upgrades Andre
No argument from me. I've got no hate for the Tonka trucks, but they aren't for me.
This content is huge for real world testing because these are common upgrades and it’s great to know the impact.
Andre! Looking good! Thanks for keeping the steelies!
Agreed. Early on, there were so many calls for him to change the rims, even a couple or more here. But I'm glad he stayed stock.
Awesome Andre! By the way, that 0-60 spot is where we do our top speed RC car runs!!
Truck looks good I think you did it right andre XL with a leveling kit & off road tires plus you have the hybrid with the big fuel tank that is like the dream setup you can drive that truck far without stopping for gas compared to normal tank in a xl or xlt
Man I was really hoping you’d grab a set of aluminum take offs ,when you swapped tires. Love your truck especially the color ,all it needs are a decent set of aluminum wheels! You would have got back some of those lost ponies and mpg from reduced unsprung weight .
Completely transformed the look of that truck. Looks great Andre.
Thank you.
Looks great Andre! I think you picked the perfect size tire. Did not lose much performance with better ground clearance
Great video as always!
Wow that's awesome dude! The truck looks MUCH better in my opinion, and with the increased capabilities I would say very much worth the price. Tried to listen for it but maybe I missed it....... how did the bigger tires effect ride quality?
Awesome vid dude!
TFL, Doug DeMuro, Car Wizard seem honest reviewers because they are not sponsored by the manufacturer. I have many others blocked because it is obvious they are sponsored. Does anyone know of other reviewers that are not sponsored by manufacturer? I will look for them.
Great vid, Andre!
Hi Andrey I loved your video. Just a helpful tip, For every 1 inch in diameter you go up on tire size you gain a half inch in height “lift”. If you went up in tire size by 2 inches then that correlates to 1 inch gained in height “lift”. Measure your 31s straight down the middle from top to bottom and then measure the 34s and you will see it will be 1inch taller and not 2 inches taller
The diameter should still be 2” bigger but it’s the radius that’s only 1” bigger. So that would be middle of the rim to the ground which is the gained height not the top to bottom of the whole tire
@@donekadamore5907 - Exactly!!! Even then,,, it’s not an exact thing. He went from a 4 ply P Metric sized tire to a 8 ply LT Metric sized tire. The sidewalls flex less so there could be another 1/8th to 1/4 inch in height due to less flex in the sidewall. Now I’m just beating the differences to death, but sold a lot of tires in my life and these discussions happened often,,,,,, hahaha.
I'm pretty impressed just how little of an impact the leveling kit and bigger tires had on the truck. I was predicting 20 mpg, and I thought maybe it'd be about .75 sec to 1 sec slower to 60.
The only thing this truck is missing is a plug in version. Being able to drive 20-25 miles a day without using gas would be great then having the generator and hybrid efficiency benefits would be awesome.
50 miles minimum
With technology there's no reason we can't get 100 miles in electric only modes...
@@truckercowboyed2638 - Technology, yes, but the batteries are HEAVY. Every pound you add to the batteries, you take away from payload. I only speak of an average commuter, but 25 miles is more than enough with room to spare for grocery shopping and the odd daily side trips. Now, in my case, when I was working, I had a drive of 1.25 hours,,,, one way,,, and the same back. I would need a full on EV to run emissions free. The plug in hybrid CUV/SUVs get around the 75 mpgE. That’s can add up significantly,,, not sure if the 25 miles of EV driving only for part of the trip is best or using hybrid mode with the fully charged battery instead,,,,.
It really is different for everyone, so there is no ONE answer. There’s just the fact that if you lose 250 lbs of payload to extra batteries,,,,, that’s significant, and would definitely be a factor for me.
Now find out how to add more power
@@chasetopsecret2018 - there’s no need for more power.
About time Andre. Looks so much better!
Run a similar set up. It's minimal loss until you start pushing 75-80 then it's 3-4 mpg
Looks great, Andre!
Great video fellas yet again!
Much better looking Andre, definitely looks like it can tame some of those rough off road segments in Colorado.
What I think is your truck looks fantastic!!! I would have done same mods. And I love the work truck rims!
Speedo, mpg calculator, and odometer are going to be slightly off, but not much. My '22 came with 275/60/20's. With a 2" RC level and 35/11.5/20's my speed is within 1mph until 55mph, then 2mph from 60-75mph. Fuel mileage isn't much different with the 5.0, lower of course, but not much. Avg 15-16mpg in town and 19-21hwy depending on speed.
The truck look so good now! Congratulations Andre
Your truck looks like a real truck now with that level kit. Looks great. Should come stock like this
I got steelies on my 21’ F150 crew cab. You convinced me to get the KO2s for it. Looks sick!
I have that same tire size, I really like them and didn't want to risk 35s. Went with a Bilstein 6112 kit up front to level out then replaced the rear blocks to get some rake back.
I w we not with raptor wheels for the slight offset change without getting too crazy. I've noticed very little affect with those tires on my 2.7eb. if the hybrid version was available when I got mine, that would have been the one. Great video 👍
Looks fantastic with those tires I'm sure glad you got that pick up it's nice
It looks really good Andre!
Andre's truck is my favorite TFL truck. His and the RAM Cummins, in that order
Nice video, Good to see real world results on a hybrid. You could have probably bought a nice cheap set of factory take-off aluminum wheels on marketplace to increase its appearance before mounting the new tires.
He has always said he likes the steel wheels and has always intended to keep them?
Not everyone like alloy wheels. I am surprised by how the steel wheels look, but I would have done exactly what you mentioned!! I’m not a steel wheel fan.
Stock setup: 22.5 MPG / 5.61s 0-60
Leveling kit and offroad tires: 22.1 MPG / 6.19s 0-60
I have a 2013 f-150.fx4 5.0 coyote v8. I have a 2 inch coil over rough country lift with 3 inch blocks in the rear with the Rough country v2 shocks. I running a 33x11x18 Falken wildpeak atw3 tires and 18 inch fuel wheels. I love it. I recommend the v2 shocks
Andre There is absolutely nothing wrong with those numbers. Super Awesome man. And Really nice truck you have there by the way.
Andre! Really dig the new set up. Looks so much better. I’d like to see an update! How are you liking it? What’s the ride quality like? I’d like to see it hooked up to a couple of trailers to see what the squat looks like with the level installed. And maybe a future video with something like the Roush/Fox 2.0s installed and a comparison. I’ll be leveling my 2021 XLT sometime before next summer and I’m trying to decide between the spacer and the fox set up. Thanks!
Your truck looks so good with those tires and leveling kit
There ya go that’s the first thing I did when I got my f150 was get a lift and some 33 KO2s. Thinking about 35s next but I’m doing little mods here and there
Hybrids are 3.73, so running 34's vs 32's helps out on the highway giving a taller ratio. Should see if you can give it a software update to correct for tire size.
$100 for the spacer kit and $300 for install and alignment is a really good price. I reached out to a suspension shop here in Michigan about having the same thing done and they wanted $800 for the whole thing
The truck looks good with your changes Andre......I bet that change in sidewall height/Aspect ratio to 75 will be a nice smooth ride.....I personally would have left it at the stock ride height if possible then leveled it and if I was too raise it I would have gone with 1" as to not get any bigger of a gap in between the tire and fender well without anything rubbing of course.
I got my 2022 Powerboost Lariat on July 7 (ordered Feb 25). It came with 275/75/18 Goodyear tires. I’ve put over 6000 miles on it since then, 4000 or so towing a 29’ travel trailer to Washington State and back. I’ve averaged about 11 mpg towing and 23-25 mpg otherwise. Towing mileage is about the same as my 5.0 ‘18 Lariat and 6.0 f250 06’ powerstroke pulling the same trailer. I got 36 mpg once on a 60 mi trip but then that was from Monument, CO to Pueblo, CO (all down hill). Keeping one’s foot out of those turbos has a bigger effect on gas mileage than anything else as well as terrain, wind and speed or some combination thereof.
Absolutely crazy how just a level kit and bigger tires really waken the thing up. Makes me feel not so bad about owning a vinyl floored ‘22 XL 2.7
Great truck. Impressive 0-60. I’m surprised and happy for you that the MPG didn’t really drop. Are those tires E or D rated? I was curious if the ride quality changed if it heavier duty tire. Thanks for the videos. I always enjoy them.
I got a 22 f 150 2 wheel drive 5.0 3.31 dif reg cab 8 ft box, getting 21mpg all the time. Today drove 469 miles 65 mph burnt 18.167 gallon 25.8 mpg.
My 2018 STX supercrew 4x4 still has the factory 20's and 275/55R20 tires. (32 inches). I eventually will do a basic leveling kit and 275/60/R20 tires (33 inches) This gives me hope that I may not really loose any fuel mileage if I pick my tire carefully. Lucky for me the brand A/T tire that was on it when I bought it comes in a 33 inch tire.
I"m keeping my factory wheels 1)because I like them and 2) when it comes to offroading, I don't really take my truck anyplace that a 20 inch wheel will be a problem.
Thank you this is the info i wanted! Got the powerboost on order and i want a 2 inch lift and 34 inch tires always wonder about the effect it’ll have
I had a 2000 f150 v6 manual with the adjustable torsion bars on the front where you could loosen or tight two bolts and the front would go up and down. With the nose down I got 18 mpg combined driving and with it leveled with bed, it got 16.
I think bfg recommends at least an 8” wide rim for their 285 75 R17. That stock rim in either 7 or 7.5”. Don’t be surprised if it wears uneven in the middle of the tire.
Looks like he may be ok if the rim is 7.5”, after a quick little search on the website the rim width range for a 285/75r17 is 7.50-9.50 but good point! I thought the same exact thing so when I saw your comment I was very curious
Edit: Those tires are also insanely heavy haha
That truck is a sub-five second (0-60 mph) truck down here at Sea Level. That is nuts!
Truck looks awesome👍🏾
Your truck looks great with that setup 👌
I have a 2018 RAM 1500 express with the factory 31" tires. I went to a aftermarket wheel, and 34" LT tires. I lost nearly 6mpg. I put my stock units back on after that.
Great Choice on that Ford they build the best trucks on the market.
As always - really enjoy all your videos - spectacular content and relevance! I'm within a week of having the Roush Fox 2.0 Suspension Kit installed (I'd be curious as to your thoughts on this particular kit), and debating as to whether I want to include new tires. My 2021 F150 Lariat FX4 5.0 has a bit over 12k in mileage so the stock OEM tires (Hankook AT 275/60/R20, 33's) are still viable. To save some money after making such an investment in this leveling kit, I might be better off wearing down the stock tires. I have considered Falkan Wildpeak AT3W 275/65/R20 or same OEM size as noted... Thank you!
Nice to see that it didn't make that big of a change. I drive a 2022 F150 Lariat with the PowerBoost. I did a 3" lift and slightly larger Goodyear Duratracs before I even picked it up, so couldn't compare to stock. Averaging about 11L/100km, which is better than my '21 EcoBoost was. I know you said it was old, but what app is that you're using?
Nice looking truck.
Thank you for keeping stock wheels! Looks great!
Yes!
Awesome Andre, can you please do an interior cabin sound test with the new tires? I am trying to avoid highway road noise. Thank you
Truck looks perfect now Andrey!
I put that size tire on my Ram 1500. Fuel economy stayed the same. Stocks were 33” tall, new tires are 33.8” tall. Went from 20” rim to 17”.
Smaller rims is the way to go on a truck
My 5.3 silverado went from 18 to 13. Same drive I'd been doing for a year. Level and 285s.
Hey Andre, the truck looks great. I'm just wondering how much the new height affects loading and unloading cargo in the bed? Thanks for another fun video. 😁
I would have liked to know what the trucks odometer said. How far off was your speedometer after the tire install?
for testing on different tyres, etc., using GPS to determine speed is critical - also use a 3rd party app for distance travelled not the vehicle odometer.. all's good, besides.
That’s exactly what I did. Used Altimeter app for speed and distance.
I own a 2017 Ram Rebel that I've had the air suspension removed from. When I switched it out to steel springs I put a 2" level in the front and 1" lift spring in the back, and went from the stock sized tire (285/70R17) to a 35×12R17. I lost about .4 to .6 mpg, and while I'm sure it is slower to 60, by the seat of the pants it didn't lose much there either
Cool that your Ford recalibrates for premium. Even better that the premium offsets the bigger tires vs stock on reg. Thanks for showing what the average guy can expect from his own personal truck that we would actually buy and the stuff we would actually do to them
Great overview sir! Wish Ford would offer HDPP with Powerboost!
We’re the Russo’s did a comparison on their camper van and it was less than 1 MPG between off-road and stock tires. So this result with a lift and tires seems accurate
Andre when you had the lift and tires installed did you also get the headlights re-aimed? That’s a pet peeve of mine. People get their trucks lifted or whatever with no thought to headlights and then everyone else gets blinded.
My 1994 GMC Yukon gets 20HWY and 12CITY, with a 2” lift and 295/75r16 all terrains on it. It also has 260,000 on it. Before I lifted it and put bigger tires on it, it got 22HWY and 14CITY. It has a 350TBI in it with headers, true dual exhaust with no CATs into a Flowmaster 10 series and a mild RV cam. And I paid $4500 for it.
Can you pull the air dam and test again? I’ve heard removing it on a leveled truck doesn’t effect mpg. I’ve never seen a real world test of it.
