what are the largest wheels in terms of width and diameter i can put on a stock z4M with no rubbing?

tirerack.com

Depends on the wheel really, but tirerack can set you free.

killjohnnyforan · 08-23-2007, 10:07 PM

its really that accurate, wasn't sure, thanks

Dammmittt · 08-23-2007, 10:12 PM

Every car is different, and so are the wheels. Tirerack does as good or better of a job keeping up with the dimesions than anyone.

going to see what the retailer in CT has to say about some 19 inch BBS RS-Gt's, 19 by 8 and 19 by 10 in the back... unless 8.5 fits upfront

8.5 front will fit with no problems.

i'm wondering... some guy locally is selling a set of 20" 8.5 & 9.5 that were on an E46 M3.

would those fit?

inTgr8r · 08-24-2007, 05:58 AM

JMO, but I think 20" are a little over the top on this car...
But, yeah the normal M3 offsets should work, unless he was extreme with rolled fenders etc.

Monster truck wheels with the right suspension

Waldorf · 08-24-2007, 10:41 AM

I was considering them because they're nice and cheap as hell. the guy was selling the set for $900.

after seeing them, they're in pretty bad shape. so, no 20"ers for me.

Dammmittt · 08-24-2007, 11:21 AM

8.5 is stock width for the front...

Well, it's close.

Dammmittt · 08-24-2007, 11:42 AM

Did you measure? Are they closer to 8.25 or something?

pbdm4k · 08-26-2007, 12:22 AM

I believe stock sizing for 18" rims are 18x8 and 18x8.5 for front and back respectively.
17" rims are 17x7 all around.

I picked up a set of 18x8 and 18x9 for myself.

Rick Hunter · 08-26-2007, 01:50 AM

Stock ///M rims:
18 x 8 ET42 front with 225/45/18 tires
18 x 9 ET30 rear with 255/40/18 tires

These wheels fit a 1 series, they will probably fit your Z
