Wheel Offset and Backspacing Explained

Do you know the difference between wheel offset and backspacing? If not, here is a quick explanation. To learn more about wheels check out the full video: • Wheel Offset and Backs...

[@fiftyshadesofurban]

I have watched videos that are like way longer and I could not understand offset and backspacing, but the way it's explained here is so simple and exact.

[@TrailRecon]

Thank you!

[@Papo9015Quiles]

😅 I agree! Finally I get it now

A very neat mixing of metric and imperial units there...

[@JarradDRS]

Best explanation of offset I’ve ever seen!

[@mikebythesea45]

Offset in MM. backspace in inches. P metric diameter tire with an inch diameter wheel. It’s a wonder how the wheels go ‘round.

[@rodmarr1844]

....and percentage for tire aspect ratio!🤣🤣

[@juanray2614]

@mikebythesea2972 what does backspace in inches look like when purchasing a wheel on a site? Can you give me an example?

[@dwayneh9061]

Yep. I put zero offset KMC on my 2021 Tacoma. Westcott lift install next week.

[@ronniejohnson317]

Another thing that can be a problem is sidewall deflection. If you have a tire with too much wall or a wheel that isn’t centered in the wheel well, the deflection can cause rub. A low tire can shred a fender.

[@matthewgorman1088]

Literally easiest explanation I’ve seen

[@1malikalik]

Said another way, " if you can't explain a complex topic in a SHORT YT Video then you don't understand it well enough" Thanks Brad

[@ScarabChris]

My first car was a 1978 Monte Carlo. This was in 1991. Back then in the south Florida high school, the G-Body cars were popular, more so as low riders. Ok the back story is there. I had my 1978 MC slammed and I had 15x8 reverse (offset) KMC Spoons on 195/50/15 tires. Back then it was the only way to get the proper stance on a G-Body low rider.

[@2blazedinfl]

i thought backspacing was from the hub surface to the mounting surface of the tire (inside of lip)

[@MussaKZN]

He goes from metric to imperial in a heartbeat. Must be Canadian.

[@alphanerd2305]

I do this a lot in my shop. But then, I only live 3 hours from the Canadian border. So, the only conclusion that can be drawn here is that being Canadian is contagious!?

[@skxj]

Lots of material wood,drywall and glass sheet in particular comes in imperial and metric sizes ie you'd order sheet size in imperial but the thiçkness is metric 48 x 96 3mm

[@MussaKZN]

@@skxj I order a subway 305mm nothing needs to be Imperial and metric in the same sentence. just saying.

[@skxj]

@@MussaKZN I think being Canadian and growing up learning both through school imperial at first then metric from 1977 onward is why it doesn't seem strange to me. I'm glad I know both systems. When I go to subway I order a foot long rather than a 305 Haha but I'll have try that next time.

[@phild9813]

Can’t forget to include the width of the wheel in addition to these measurements to be able to assess how far the wheel will “stick out” compared to factory or any other wheel you might have.

[@Smedleydog1]

You added the thickness of the ruler to your measurement. It's probably only 1.5-2mm but it can make a difference.

[@on1ytheb3st]

Wheel width is just as important in this calculation; it’s actually used to derive backspacing or compare offsets between wheels

[@danielsharon524]

Spot on.

[@bartenz4307]

20+ years ago, it common to add 1/2 inch in wheel track

[@wsfwsf1497]

Some mfg makes an adjustable mockup type wheel, so you can play with different offsets, backspacing, etc.

[@OldAndGettingOlder]

Offset and backspace. They're the same answer to different formulas.

[@RedHatAlex]

Thanks. Finally

[@NativeEffect]

Thanks bro

[@pierrecolombo4654]

Wondering if upsizing the rim width while keeping the same offset will fill the gap between the wheels and the fenders or if the additional width will go on the suspension side? Thanks!

[@Mango_ventures]

been wondering if I could do 37s on my 392 wheels without rubbing on the sway bar or arms

[@TrailRecon]

If you have the right wheels you will clear the sway bar and arms just fine, but without a lift and the correct bump stop you might get into your fenders a bit.

[@Mango_ventures]

@@TrailRecon might go to 35s and a small lift, I really like the factory 392 wheels

[@Testing-123]

Just had a conversation with a buddy a few months ago

[@roberthdavisii]

Why are we using two different distance measurement systems for the same application?

[@frankbreuer8849]

Question: with backspacer mounted what is the measurement between the outer rim and the mounting plane? It should be equivalent to negative offset. Correct?

[@dimvol8605]

Hello, I have a Subaru Outback. The factory rim size is 7JX18ET55. I want to change the rims to 17 inch Subaru comes with the following sizes 7JX17ET 55 or 48. I can't find any rims that size but 8JX17 ET38 or 7.5JX17ET55 and with the 18 inch 8JX18ET30. My question is can you mount the rims that are not exactly the same size or not. Thanks

[@juanray2614]

Okay so if the wheel has a “0”offset & backspace of 4.4 inch’s what size & width is the wheel you have there? My other question is, if I was to purchase me a wheel that’s 18x8.5 for the front & 18x9.5 for the rear, but I want my wheel to stick out of my fender close to half way with a 4.5 backspace what wheel size should I get & I always see a lot of +22 +30 15 or 20 without the + how do I know it’s a negative offset if it doesn’t have a - beside it?

[@jpadamada]

This. This is the video.

[@commasNculture]

So I’m looking at getting a set off wheels for my sl500 20x10 offset 38 but I saw on a wheel chart it’s recommended that with that wheel size I use 23 offset. How can I remedy this ?

[@thomashesse4446]

My measuring tape also has tenths of an inch

[@raypabs5374]

This is why i just keep the OEM wheels on my car so that i dont have to worry about this.

[@cbrucesbiz]

OK, I have a Jeep so which is best to have or does it depend?

[@yolisurich4025]

back spacing always looks better. Originally when mag wheels were developed that was the look everybody wanted. I think wheels with no back spacing are a waste of money. I don't like that look at all. I think that's a factory look. Also, the reason everybody wanted mags was they wanted to increase the width of wheels. Tiger paws were one of the first wide tires and then Goodyear custom wide treads. And with new aftermarket fender flares everybody can go wider.

[@clarkclifford2338]

Great presentation! My only criticism is that, mm and inches are mixed. 12mm, 38mm, 4.4 inches.

[@nigelskinner8799]

That's probably because he has one of the very few tape measures in the USA with both metric and imperial.

actually the last statement is incorrect. Backspacing is the distance from the back of the wheel to the inside of the lip.Where the bead seats.

[@TrailRecon]

Backspacing is the measurement from the mounting surface to the back of the wheel, and I'm pretty sure that's what I said.

[@timothylessing4774]

Is it 4.4" because the rim width is 8.8"? Or maybe rim is 8.5 with 0.3 being taken up by the Bead?¿?
