15x8 with +15 offset

Has anyone tried or knows if this size 15x8 with a +15 offset will fit a 2002 Mini? I found this size wheel on Ebay for $300 for 4. The way I see it the inside will go out 3/8" and the outside will extend 1 3/8" further. Can I exspeck any other problems?

I have 15x8 with +36mm offset. Fits the fronts but rubs the rear trailing arm in the rear on a 2003 MCS lowered with Coilovers.

What suspension mods do you have? How much lowered?
What tires do you plan on using?

What are you going to use these wheels for? Street/track/autocross?

Ideally you want 4x100 bolt pattern, 15x8 with +30 to +33mm offset.

Otherwise the higher the offset number the more likely you will need spacers. I use a 3mm spacer in the rear, but a 5mm spacer would also work.

+15mm offset means your wheel will stick way out of the wheel well about 20 to 30mm more than stock. While this makes your track wider it also creates problems if your tires are stock sized or larger and if you have lowered your MINI. In which case you might need fender flares or a wider fender kit.

If you use tires that are smaller than stock in tire diameter you might be OK but it will look like your tires don't fit in your wheel wells.

Try calling Alex@tirerack.com to see if he has any experience with this setup for a MINI and what tires to choose.

This is for street application. I just like odd school look. Plan on 205/50 15 tire, car is not lowered. With a +15 offeet I should not require a spacer. I just worry about tire rub. May have to run a 195/50 15. Just have to study the sizes.

I just posted in your other thread agreeing with the 195/50 choice....but if you're gonna run such an aggressive offset, i dont think you'll be able to pull it off visually without some coilovers.

When you get down to 205/50's and 195/50's you're increasing the wheel gap a substantial amount ...half an inch and up...... you can't really be running around with that kind of offset and wheelgap without it looking a little goofy.

Let me know if you wanna see more pics of my 15x8 et 15 and 15x8.5 et9

Your tire size selection is not the best for 15x8" rims.

For 15x7 it would be fine.

195/50-15 fits rims 5.5-7" and perfect fit for 6", 22.7" tire diameter
205/50-15 fits rims 5.5-7.5" and perfect fit for 6.5", 22.8" tire diameter

The 205/50-15 can be stretched to fit the 8" wide rim but it will take a bit of effort and will look like the tire doesn't match the rim. I know this is the look some people want (common with VWs).

Stock tire diameter is about 24.3" so 1.5" smaller tires will need some sort of drop. I have coilovers with 1.8" drop front and rear.


15x8 rims +36mm offset, 3mm rear spacer, 225/45-15 tires

Your wheel gap would be huge with stock suspension, and tires would be sticking out 20mm more than mine, almost an inch out.

If you really want to pick a good tire size then look at-

225/50-15 fits rims 6-8" and perfect fit for 7", 23.9" tire diameter
Good example for street use would be
BF Goodrich g-Force Sport $92 each 340 treadwear 23 lbs each
or maybe same tire in
215/50-15 $85 fits rims 6-7.5" and perfect fit for 7", 23.5" tire diameter

Both these are larger than 205/50-15 tire diameter so wheel gap is not as bad but hopefully still wide enough for the 8" rim.

225/50-15 is quite a common size.

I guess it would depend on what you call a "good tire size"

I don't think there is anyway you could run those sizes with that width and offset. I run a 15x8 et15 on the front of my car with 205/50's slightly stretched on. Granted....my car is lowered, but it literally knocked the fenders off at first (prior to me getting all the fitment things in order). Even stock i think you would see a lot of rubbing if you went with those tire sizes.

People can call thinner tires on wider wheels "mismatched"....but i think it's more of a mismatch if tread is showing outside the fender which would definitely be true with 225s on that offset. I think that if you're gonna go that width....you're gonna have to look towards lowering the car as well and begin thinking about 205/50's or 195/50's.

I'm uploading a better pic to show you how much poke it is...

Here's a new pic....i left it a bit big so you could look closer. This is 15x8 et15 205/50 up front (rears are wider...so pay no attention back there ). This is also with zero camber and lowered on coilovers. I do believe that it's probably lower than most springs would take you.....so you could just envision it higher if springs are the route you might take.

In person it really doesnt look like this much....but its a good pic to judge off of.

You bring up some good points not addressed.

225/50-15 will fit the wider 8" rim but the result is the tire tread width is significantly wider once mounted and in the front as mentioned now you have much less clearance for a "turning wheel". Rubbing happens due to the offset and width of the tire. With 205/50-15 you have a much more narrow tread width even mounted so you get a bit more clearance.

The rear wheels don't turn so it's possible a wider tire would work- maybe with a little adjustment.

Wider tires also mean more weight, about 3 pounds more for each tire vs the more narrow 205/50-15.

Both these example pictures show coilover suspensions which are ride height adjustable so clearance and wheel gap is tunable.

Mismatched is anything that isn't well coordinated from tires and rims of sizes that are not optimal to wheels sticking out the sides of our cars.

That's a pretty aggressive look to the tires sticking out. I've seen a MINI with that look from mounting 15x9" Kodiak rims and wheel arch fender flares.

Yah my rears are at the same position as his kodiaks because they are 8.5's with a slightly lower offset than his 9's. I will be doing some custom fender work shortly to slightly extend the fender flares (not enough to call it widebody).

There is a lot that goes into making sure a rim like this can fit, bassles.....so i would definitely continue thinking about tire size and clearance.

Hello Rally Stance Design. I have been reading up and want to purchase some XXR 15x8 inch wheels for my 07 mini s. I want to lower the car about an inch (or 1.5). What do you think would be the best offset and tire size to achieve the poked out wheel look? Do I need coilovers, or can I go with just springs. Thanks!!!
