The original tire sizes you quoted would be the best. 225 vs 235 on the front won't make as much difference as you're hoping for. Offset of the wheel plays a bigger factor.

Depending on how low you are, camber is the solution. It won't have to be dramatic as the other guys have mentioned.

I wish there was a fitment fairy because offsets, tire specs (rounded vs square) and lowering confuse me to no end. I have et40 front and et42 rear 19x8.5 235/35 with lots of room but I'm really low on h&r coilover

thanks for the reply
I had 235/35-19 on 8,5 ET34 in front. Michelin PSS.
Rubbed like crazy. Swapped to PSS 225/35-19 on same wheel. No rubbing. Even when pushed at the track.

No adjustable camber plates, only pulled the pins from the OEM guide supports.
Running OEM shocks and H&R springs.

Hello all I'm a newb on here, and recently purchased my 03 Z4 manual tranny 2.5l Grey as a project sunny weekender car. (completely stock not lowered) I have an opportunity to purchase a used set of CSL style reps matte black but I'm a little concerned as to the offset and fitment on the rears. Strangely enough the guy say's he doesn't have time to allow me to try the fitment as he's selling for his dad and letting go really cheap. Here's the specs your expertise would be most appreciated, the rears are the concern:

19" x 8.5" +35 Offset with 235/35/19 fronts
19" x 10" +33 Offset with 265/30/19 rears ( 10" WIDTH!!! +33MM OFFSET)

Those seem more in line with M specs, the 10 rear with low 30 offset will most likely rub and/or stick out too far past fender.

If you are going for a show car look with LOTS of camber, they may fit but you will most likely rub unless you roll/pull the fenders. Anything can be done, it depends on what you're willing to go through with.

Your rears will stick out of the car 7mm more than my setup, I think with HEAVY rear camber it can be done. I've run a 9.5" rim on a 32 offset.

My rears are 10" ET41 with 265/30. I have tried 3mm spacers. Startet to rub a little. So ET33 will rub without work on the fenders and negative camber.

I honestly think if they decide to run more than 2.5 deg of camber, it may work. Tire won't last long, but it might look sick.

3002tii, 3GFX, and StigJ, thanks for the response, I very much appreciate it, as usual I was swept up by the deal and not the reality of proper fitment, so I will continue my search. Cheers!

Fit? Yes. Work? Depending on your definition.

Front maybe. A little wide tires. 2007 3.0si doesn't use TPMS. So no need for those.
Rears are too low offset in addition to a little too wide tires. I have 10" with 265 ET41. The ones you are considering will stick out 16mm more than mine. I had a tiny rubbing on my Michelin PS4S at the racetrack. On daily basis its all good.

I'm running Apex Arc-8
Front - 245/35/18 on 18x9.5 et35 +10mm spacer so et25
Rear - 245/35/18 on 18x9.5 et35 + 10mm spacer so et25

There is slight rubbing on heavy cornering or on bumps. But only hitting the plastic cover.

Search or google the specs of those rims. You need to know the width and offset. Then simply compare to what data is already here in the thread (do some reading).


Based on the tire width, it will all come down to your offset of the rim to know if you will rub somewhere. Judging by the widths you should have plenty of room on the sides. Having said that the tires on the wheels have an aspect ratio of 5 great than stock. So your diameter and circumference will be larger by that amount.

Will it fit? Most likely. They could fill our your arches better if you're not lowered because the overall diameters are larger. You car will be slightly higher off the ground as well. Will your speedometer read wrong? Most definitely.

Talking about tight fitment! These wheels came off my non running E46 M3.
Enkreuz HS10
F: 19x8.5 235/35
R: 19x10 295/30
Unsure of the offset though since these are 3piece wheels

Looks good, with a 275 / 265 in the rear It would be ideal!

Rub?!

I was thinking maybe even 285 since someone is selling a pair Pirelli locally for a really good price. Yes it rub but I'm on air suspension, no need to worry about rubbing. It could clear the 295 as well, just need a light fender full
