Tires rims

I'm thinking of getting NT 555 extreme ZR tires for my 2004 z4 2.5 ,,235 40 18 front 265 35 rear , with 18" niche wheels . Would 18x8 on the front , and 18x9.5 rear look good? I was debating between 18x8 or 18x8.5 on the front. Will either work?

Here are my Breyton GTS-R wheels on the coupe.

225/40R18x7.5 et 45 with a 12mm spacer up front

255/35R18x8.5 et 48 with no spacer in the back

Over a seriously aggressive bump, the front rubbed for a split second on the fender. This makes no sense to me based on all the calcs I have done. Unless the 7.5" wheel making the shoulder of the tire is more square caused it, but I still think there should be plenty of room. Tired are Direzza ZII which are also a little more square than a PS2.

07 z4 3.0si  [0.00]
So after months of contemplating which wheels to definitely buy this spring, I've opted to go with apex ps-7. After searching a few times, I've noticed that according to some posts from apex the correct fitment for a non m is 8.5" ET35 and 9.5" ET43 fitment. Which basically leads to both wheels being the same profile and at the minimum i wanted profile 2 in the rear. When I went on turner motorsports site, they have listed that ET33 9.5" fits. Wondering if anybody could shine some light on if this fitment would work. Also,car is lowered with bilstein struts n h&r springs and have rogue engineerings adjustable RCA if that would help at all. Any insight would be appreciated!

Can I run 550i wheels

This may have been discussed but I can't find it. Can I run my 2014 BMW 550i wheels on the 2006 Z4? They are 19x8.5 ET33 and 19x9 ET44. Tires are 245/40 and 275/35. I guessing too big. I put M5 wheels on the 550 so I've got them sitting around and figure they would look a lot better than the little 17" on it now.

LOL no, but I found the 22's. It was actually another forum, but worth linking to see his 20's on the front and 22's in the rear. Not my style, but shows it can be done.

Idea piqued my interest. Anyone tried Style 5's? I've only been able to see 1 picture on a google search, but it was a roadster. Curious on how they would look on a 3.0 coupe.

I found a good deal on a 18x8 +15 with a 225/40/18, will it fit on a 03 Z4 non sport-roadster?

Here's a little help for those wondering about fitment with the following specs:

Front 18x8.5" ET43 Tire: 235/40/18

Rear: 18x9.5" ET43 Tire: 255/35/18

The tires came with the wheels and are finished, I would go 225 in front and 265 rear.





Opinions on the color of the wheel center piece and on the wheel set in general are welcome.. I'm still not convinced I like them haha

Does anyone know whether 235/35/19 and 265/30/29 will have any rubbing issues on standard 3.0si?(Planning to lower it a bit tho).

Wheels are 19 x 8.5J ET33 front, 9.5J ET40 rear. Any inputs will be appreciated!

9.5" is the perfect size for 265/35/18. No need to worry.

Well I went with kendas...these will be huge compared to the current stock wheel tire combo on my 03 2.5! The tires may not be high quality but they have a killer tread pattern and if I decide not to keep the car for long I won't be out too much tire money since I was able to get the entire setup (wheels and tires) brand new and shipped for under 1k.

Bump for those who may be looking for it.


Shouldn't this be stickied like the M thread?

Here's my contribution! 2006 3.0Si on M-Sport Suspension Stock Height

225/40R 18 x 8.5 et 35
255/35R 18 x 9.5 et 45
VMR 710 in Gunmetal Finish

I think that a 18x9.5 + 35 would fit much nicer than the 45 in the rear if you want to get more aggressive.
