- In this video I’ll talk about wheel offset, what it is and why it’s important especially for lifted vehicle and suspension and wheel well clearance.
Be sure to check out PitStopOverland.com and the wide selection of off road tires. - ยานยนต์และพาหนะ
Here is the calculation for tire height in inches:
Example (195/65/15)
A/B/C
A divided by 25.4 = 7.67 (width of tire in inches)
7.67 x .65 (B) = 4.99 (shoulder height of tire)
4.99 + 4.99 (top and bottom shoulder heights)
9.98 + 15 (C rim height) = 24.98” (top + bottom shoulder height + rim = total height of tire)
195/65/15 (Total Height of 24.98” Width of 7.67”)
where did u get the 25.4 from?
@@tjgrafiks 25.4 is the conversion variable to change the (mm) to inches from an aspect ratio. (25.4mm = 1 in)
@@ThePitStopTirePros ah ok. new to this and learning. so how do we know what size rim to get or what width to get. I currently have 225/70/16 on my crossover vehicle. it's called a Honda Crossroad out of japan not sold in the U.S. I want to put wider tires. based on the formula my mounted diameter is around 28" or so which is correct bcuz i measured by tape the other day lol. my wheel well width is just under 31" from the widest section. I"m also lifting my car by 2" inches. I just don't want to screw ordering the wrong size tire and rim. not sure if I need to drop down to 15" for an offroad or aggressive tire.
would be great if u could help. I don't know how much negative offset I need. I'm looking at a 15/16" rims on ebay with a -19 offset. have no clue if it's enough or too much lol all I know is that everything needs to be maybe a tad bit under 30" to be safe. 29.5-.75 but can't find anything in that range. I was thinking maybe 255/65/16?
so would I need a rim at least 10" in depth? but it also seems that off road/MT with the same specs are a little bigger bcuz of the thicker exterior or the design
Finally a video that made me undestand offsets, i find this REALLY confusing, now i understand it. Thanks a lot!
I don't even have a truck,but when he started explaining everything so clearly I had to finish watching the video. Job well done 👍🏾💯
These 'lift kits' should come with their own vehicle specific tire/wheel size recommendations to support their product. This would leave the guess work out for the vehicle owner. Great video!
Most of the manufacturers we’ve worked with do come with a recommendation either stated in their tech specs or front or back of any install guides. If not we contact the manufacturer directly to talk to their tech department for a recommendation. Having a plan for all aspects of the build allow for minor adaptations but with the highest probability of successful aesthetics and performance.
GREAT job explaining this! Thanks for making this video!
That four-wheeler in the back needs some air in that tire 🤣
Don't be that person
Finally a fast, simple explanation. 🙏🏼!!!
Great video. Thanks man.
Great info! Thanks man
Great explanation thanks.
Perfect explanation
CLEAR CUT EXPLANATION/DEMONSTRATION. THANKS
Good info!
Great video explanation! I just bought an 06 4Runner Limited and it has a 1” front spacer kit lift in it. Bought new wheels that are 17x8.5 -12.. I’m thinking of running 265/70/18 falken wildpeaks, based on your opinion should I be fine with this tire size? Thanks!
Awesome 😎 thanks
Can you please tell me if this would work for my 2022 4Runner ORP? I have watched several videos but I feel so stupid because I’m just not getting it!!!
Looking at wheels that are 17x8.5 (stock are 17x7.5) and either 0 offset or +25offset. My Stock wheels are +15 offset. I want to run stock size tires 265/70/17 because I don’t plan on lifting the vehicle and don’t want to do any mods. Will this rub or be an issue? Which offset would be best? Thanks for any help…
Thanks a lot.
Thanks guys!
should also add the further offset you run away from factory the more scrub radius you add and the more impact force you add to your suspension components as they all designed around factory tolerances, I can explain but watch a video about scrub radius and you'll understand
Bought aftermarket wheels for my new edge Mustang that are too positive, will need spacers to bring them out.
Thanks for the vid, is there a way to get the -10 offset without new rims? Have a 2022 trail tacoma with 16” wheels and would like to get that wider look without breaking the bank. Appreciate it!
Offset, backspace, bolt pattern all are fixed specifications on rims. Bolt on spacers are commonly used but we do not recommend them. Additional cantilever torque on hubs can cause premature wear to bearings.
Good info thank you.
Where is ur shop located?
We are in the Western slope of Colorado
I have a stock 2019 Tundra Trd Pro with 18 inch rims. I’d like to give it a more aggressive look. Thinking about keeping the 18’s and upgrading to 37 inch tires and a 6 inch lift. What the best offset for this setup to avoid control arm and rubbing? (I’m prepared to modify plastic bumper trim.)
Test fitment is always recommended when going to aftermarket wheels but the rule to keep in mind is your stock offset +55 / +60 = 2-17” / 2.36” (mm to inches).
6 inch lift (going up) what is the ideal stance for offset to match (height vs width)? It is a preference, but a vehicle on stilts is much more prone to rollover than a vehicle with a wide base especially with the overall large footprint of a 37”. Deal with a professional when lifting to get the best information recommended by manufacturers, but your vehicle shape should look more like a triangle and less like a field goal H.
Great explanation. So my factory offset is +33 (2009 gmc canyon z71 4x4). Im looking at a set of aftermarket wheels that are a +10 offset (a differenceof 23mm). So these rims should move my rim/tire combo out .9 inches from factory if im understanding this correct)
Correct 23/ 25.4= .9055
I need to listen again. I heard that if factory is +33 that -10 would widen the stance and +10 would decrease the stance.
@@thetomasloretta anything greater than +33 will decrease the stance. For example a +45 or a +39 (both greater than +33) would decrease the stance.. So +10 is less than +33 so therefore a +10 will widen the stance.
how does the wheel width affect the offset? for example: jumping from a stock wheel on a 3rd gen taco 17x7 to a 17x8.5/9 with a +14mm offset. Having a wheel/tire that sticks out is illegal where i’m from. will having a wider wheel affect the offset? or how far the wheel sticks out even if it is a positive offset?
Wheel offset and width are two separate measurements. If you have two rims with the same offset but one is wider there will be a slight difference in more rim sticking out as well as more rim in the well. 1.5” split to .75” out of the well and .75” inside the well in your example. If you are going taller in tire size the aspect ratio will almost always dictate wider width as well, in some cases requiring a wider rim too. If your worried about too much out of well distance that has to be covered consider a well flare like some bushwhackers.
Where the link to calculate tire ratio?
My oem wheels Toyota Camry 2020 offset is 50 mm,I want change my rims for lexus rx450 h with 30 mm offset ,Will my wheels go beyond the car's fender or will it be too far inside? Or won't it change anything?
Would be impossible to say anything for certain without a test fit, but your difference is 20mm. One inch is 25.4mm so 1/5 less than one whole inch of rim outward past the current rims position.
I have a 2022 4runner and wanted to put 20x9 wheels and planning to lift 3 inches. What offset do I need to get? Negative or positive? And what size of tires do i need to get. Thanks
That will all depend on recommendations made by the lift manufacturer and their specifications, the wider the rim the more negative offset will be needed.
Good video. I currently have a 2/1 leveling kit running with 265/70R17s on my 2022 Tacoma. I am looking to get a more aggressive wheel. What offset should I consider to go with? Thanks
I have a regular 4x4 2021 Ford F-150 Can I install a 20x10 / -18 With my regular tire size ?
That would take your rim from its factory stance @+44 and push the rim out of the fender 2.44”. Would NOT recommend it. Plus the width is also over excessive
Is it possible to offset stock wheels? Is installing wheel spacers the same thing as an offset?
Is is not the same as wheel offset but can accomplish the same purpose if larger tires are mounted on stock wheels for example after lifting. The debated detriment is how much additional fulcrum torque is applied to the outer hub bearing causing premature wear and tear to wheel bearings and lug studs if a non bolted spacer is used. For example a 1/8 disc spacer reduces the total amount of threads grabbed by the lug nut ergo reducing applicable torque and load to the stud. Bolted spacers have more structural integrity but increase the fulcrum volume to the outer bearing because of the distance increased between the wheel and hub.
So I just bought new set of tires (275/70/17). I still have my stock wheels though. When I make a really sharp turns the tire is kinda rubbing against the control arms. Does changing a negative off set wheels could fix this issue? I really don't want to use spacers.
It would depend on at what point in the turning radius that the rubbing occurs. Typically more negative offset from an aftermarket rim would create more clearance. It’s also a possibility that the larger tires maybe the issue, one that negative offset may or may not fix. Lifting a vehicle, plus sizing tires, with factory or aftermarket rims is usually done with manufacturer or tire guideline for fitments.
@@ThePitStopTirePros i have a 3" lift. it's just rubbing against the control arm really.. there's still a lot of clearance elsewhere.
I have a +20 factory offset..what is the most that should be considered on a 20 inch aftermarket wheel on a 2014 camaro..the wheel is 20x8.5 with a +35 off..so would the .6 inch be too much of a change? I heard + or - 5 was ideal
Not sure your vehicle trim as most of the Camero’s have either a base model with same tires and wheels front to rear in that case the offset is + 38 for matching front and rear setups (LT option). But a ZL1 option has + 23 in front and + 43 in the rear. So according to fitment it sounds like you have some missing information to give you a proper recommendation. Based on your question I would go with a reputable seller that uses a fitment guide to properly advise you of your options for the vehicle. Offset is in mm so a few mm in either direction is typically not a big issue, but you want a company that will stand by their recommendation so any returns or exchanges are on their dime and not yours.
I have an LS..thank you for your time a recommendation.
if i put a 265/75r16 tire on a 16" wheel with a -12offset would that cause any problems on my tacoma WITHOUT a lift?
That is only a 31.64” tall tire so probably fine for second and third generation Tacos but maybe too tall for a first gen. But test fitting would be what we would do with full turn checking before releasing.
@@ThePitStopTirePros awesome thank you! thanks for answering about all gens lol i forgot to mention that. Im going back and forth between a used 1st gen or just get a 2022. Either way once i get it ill be headed out to you guys.
I just got a 17 inch wheels -12 offset, should i be worried about messing up the wheel bearings/joints? .
Any greater distance will eventually change the wear and tear of any vehicle but with proper maintenance many installed items can last just as long or longer depending on the build quality. Rims typically don’t change much unless it’s a drastic change in size and settings from factory.
Hey there. I want to ask you. My factory wheels have the following size. 7,5x17 et 25 6x139,7 bore center 106,1. I want to buy new wheels.The size that is close to my factory size is 8x17 et 20 6x139,7 bore center 106.1.
My question is will it fits or will I have an issue.
Thank you in advance for your help.
It looks like your values are all very close, you still have to factor your tire size and the applicability to the rims in question. What I would advise as just another opinion on the internet, is ask the manufacturer if they have a fitment guide to the rims your looking at installing or if not what we typically do is if there is some gray area, we always test fit with the option to return to our distributors prior to installing tires so we can verify fitment to the hubs, around the brakes and with enough backspace and clearance to safely install. With lifts companies like BDS for example they have recommended numbers that give you the rim and tires that you should fall within to match their installed product. So bottom line, get as much verified information specific to your vehicle model and aftermarket products that will get you to as much information as possible to make the best decision.
What size of tires are in the video on that taco
285/70/17 / 32.7”
Doesn't negative offset put more load on your ball joints?
No those angle typically aren’t affected by negative offset, but a bolted on spacer could do more wear and tear on the hub/bearing overtime because of the increase of fulcrum distance from the bearing center.
did you use a spacer to bring it further out? still a newbie 🙋
No it’s an aftermarket wheel that allowed the offset change.
Sorry to dig it again: whatever the offset is, when upgrading the tire, dosn't matter what size : how would you know what offset to get to accommodate the bigger tire?
Does it mean: example: factory tire: 265mm on 0 offset rim, if I want 305mm tire- 40mm difference in width - do I need to get 20mm negative offset to sit new tire in the right inside distance form the... Egz.: upper arm / coil?
It will all the depend on the current spacing between the tire and suspension arms in the wheel well. Remember that when tires are upgraded the width of the tire almost always widens with an upgrade in height because of aspect ratios. For example if you have a 1/2” gap between the upper control arm and tire currently but are upgrading to a taller tire that is also 1/2” wider then you’ll have 1/4” less room to the UCA with the same offset. But if your gaining 1/2” width, and negatively offsetting 1/2” away from the hub then your gapping will stay the same at 1/2”. Most factory offsets are a positive number typically between 20-50 and are in mm. (MM ➗25.4 = inches)
👍
How much will i stick out from fender if i throw on 20x10 -12 with 33s on a F150?
Offset is in millimeters, easy calculation is to find out the factory offset, positive number and add the additional negative number to it, divided by 25.4 and that would equal the inches you would use to determine the amount that the rim is going to pull out from the wheel well. (for example 44 + (-12 offset) = 56 total millimeters or 2.2 inches
I have a 2016 Tacoma with 4 inch BDS lift with 32.5 inch tires currently I have 18 inch Fuel wheels with -19 off set. I'm thinking of getting 18 inch TRD Po wheels with a +20 off set will these fit
You will lose 39mm or 1.54” of your offset. Meaning the rim will cause the wheel and tire to go in (the wheel well) that much distance. Hard to say if it will fit but with a 4” lift, your stance vs center of gravity will take a hit making the cornering seem much less stable and more top heavy since your are in essence narrowing your tire footprint.
@@ThePitStopTirePros What about adding wheel spacers?
@@PHILLIPS8822 you can, but there’s an additional torque applied to the hub bearing as a cause. But if your not off-road consistently shouldn’t be an issue.
@@ThePitStopTirePros I've never done off road. Any idea what brand spacers are good quality?
@@PHILLIPS8822 honestly we never do spacers at our shop, we are a heavy off-roading area. But I’m sure there’s some reputable companies for them.
I hear a lot of people who think offsets or even bigger tires can cause problems. I’m looking to get a more aggressive look on my truck but also not trying to put crazy amounts of money into it if anything was to go wrong. I just want a custom long lasting truck. Would love for you to make a pros and cons video on such things.
just get a bit bigger tires without lifting they will tell you what size would you able to use
Hope you know lifted truck taking more gas ⛽️ do not blame me guys to I advice someone
@@vumsang9746 perhaps would you know what size mm comes with a factory standard 2016 yukon Denali ???
For instance I’m look to purchase a FACTORY rim for it , but it’s asking me is it a 24mm or 31mm 🤷🏽♂️🤷🏽♂️
My assumption is 24, but I’ll rather ask to be certain!!
I still don't get offsets at all. You can have a positive offset that looks the same as negative?? like looking at +20mm and it gives a better stance than negative options. Am I missing something
@Larrybobangles
Yes, your missing the backspace.
The backspace of the wheel will change everything...
I'm surprised that he didn't bring it up...
@@jeffersonhenn1086 isnt it the other way around? the negative offset using for a wider tire will push the tire outward giving it a wider base and more clearance inside. i think he said that.
Will offset affect alignment? Or cause issues in the future?
A heavy deviation from factory offset could potentially cause premature wear and tear but have experienced customers going as far as possible with negative offset on vehicles. And the two most noticeable cause and effect issues would be an increase in road tracking (wandering in the steering wheel) and increased paint chipping on the sides of the vehicle from tires throwing rocks.
@The Pit Stop Tire Pros is -25 offset ok? 265/75/16 tyres
It would totally depend on the vehicle your adding those specifications to. Every vehicle has specific sizes (tires and rims) that will fit from factory and those that won’t. Using a fitment guide is the safest bet, not randomly choosing options. If a vehicle is modified from factory then a manufacturer recommendation is usually the specs you should use.
I drive a 2019 Chevy Silverado rst. I upgraded the suspension to Bilstein and icon ucas and now I’m sitting completely leveled. My stock rims are +24mm. I plan on install 18” rims with -12 offset wrapped in 33”x11.5. Do you think this set up will rub? Thanks for your expertise
Whenever we do any install we always take into account the recommended tire size the lift manufacturer states as the maximum tire size that will fit the vehicle after installation. Your offset difference is 1.417”. So take into account where the tire sits now and figure that distance it’s going to move outward. Whether or not it will rub depends again on the recommendation from the lift manufacturer, sometimes you have to call them, as well as the intended jump in width which your average rim is going to be 7.5-9” which 11.5” is between 22-45% wider. Even at 9” the 11.5” gives you 2.5” total increase giving you 1.25” in both directions. The offset gave you 1.417” outward and the width took away 1.25” so your left with .16” of additional clearance. Although this is all speculation as typically having our customers in shop and measuring all of this is our usual protocol. Bottom line recommendation would be to get all of your existing measurements and compare them to your desired component measurements and as long as they fall within the limits of what the wheel well will fit, plus a test fit will give you your answer.
So if it's rubbing I need to add spacers?
Spacers or a new rim with additional negative offset, in combination with more lift to accommodate better clearance of the turning radius based on the tire size that is installed.
@@ThePitStopTirePros I heard the offset is written or stamped on rims is this true? The rims I got are for wider and bigger diameter so I'm assuming I definitely need spacers. I'll get under it and see
@@tonydiazist the backside of the rim will typically have serial number (sometimes), diameter and width. Offset most likely not. Best recommendation is taking to a professional that can advise based on facts, not speculation in order to make a proper assessment.
Man I’m so confused. I am buying a +15 offset sema wheel for my Tacoma and running 265/70/17 with stock suspension. Hoping it works out
Most are offsets are a high positive #. So it should bring the tire out about 1/2” or so, and the tire should be fine for a third gen & second gen tacos, might have some issues with first gen. Just have to test fit and verify.
@@ThePitStopTirePros wow, appreciate the quick response. It’s a 2022. Thank you!
@@mistert780 I use an alignment turntable to check wheel well fitment. I would request the same for the installer.
What wheels are those?
Ultra
nice video but thats the factory spare 😂
wish I knew this before I got my wheels 💀 they're -36 offset
Yeah yeah you could have simply said... the higher the offset the closer the wheel is to your chassis and the lower the offset the further the wheel is from your chassis & everything else would have been self-explanatory but all that jargon just complicates things more than necessary 🤦🏻
i want to tell u , i did not understand anything u said..........=(
Want your truck to be the dirtiest around? Offset your snow/mud tires in winter and watch the dirt fly
Now you need to upgrade the vehicle to a real vehicle like a Chevy truck or a Jeep
Unnecessary soundtrack
You guys never measured king line and scrub radius. That’s not safe at all. You need a new knuckle that is very low from the center of the wheel. Those shocks are now greatly reduced in effectiveness as well as controlling the car is fooked
