Will an 18 x 8.5 et15 rear fit on the e90?

ac1208 · 11-14-2009, 10:55 PM

I'm found a set of winter rims and tires off an m coupe with FRONT: 18x8.5 ET38 REAR: 18x8.5 ET15

I know generally for 19's, lowest offset is 20, but for 18x8.5, will the et15 offset work?

Thanks in advance.

that should be fine on your car......just make sure you don't put the rear wheels on the front!

What! I highly doubt this will work without fender rolling

With how wide tires 225/40? If so I think it will fit.

Why 225/45 and not 225/40?

What's the difference?
Someone local is selling a set of 18" winters with these specs, and I wanted to upgrade my 17" winters to 18"s so I'm considering this set. Will it not fit?

OEM size is 225/40 for 18" wheels. 225/45 has a taller sidewall. The number in bold is the height of the sidewall in percentage of the width of the tire.

Ohh ok. My current ones are 225/40 I think. So will the 225/45r18 et15 fit my rear without rubbing?

Probably, but I can't say for sure.

lonestar22 · 11-15-2009, 08:59 PM

they should, the minor stretch of a 225 should help alot. post pics

I think ET15 for the rear is to extreme, it doesn't look right IMHO.

Orient330iNYC · 11-16-2009, 12:05 AM

i ran ET15 19X8.5 in the rear, 235/35/19, no rubbing
you should be fine with 225

ah gon · 11-16-2009, 12:13 AM

it will fit! use 225 40 18 tires should fine.

Why, remember we're talking about a 8.5" wheel with 225 tires, not some 19x9.5 wheel with 265 tires.

i had 18x8.5 et13 with a 255/35 tire with rolled fenders.
it will only rub if i have 3 at the back and with big ditches/bumps.

It'll fit.
Wheel diameter has nothing to do with offset though.
