Some M3 Confirmed Official Wheel + Brake info

Guys, whats the max tyre dimension (front and rear) that can fit on OEM 19''?

Do you mean the max tire sizes within reason?

You can technically put tire sizes on the stock 8.5 and 9.5 wide wheels that are totally ridiculous. (tires that look "cartoonish")

If you want larger than the stock tire sizes for your OEM 19's, here are the largest tire sizes that I would recommend:

Front 19x8.5 wheel: 255/35/19

Rear 19x9.5 wheel: 275/35/19

Anything larger than this will overshoot the proper tire dimensions by a significant margin. That will not improve your performance or the handling characteristics of your car. It will also add additional tire weight, and possibly cause undesirable rubbing issues due to the factory wheel offset values.

Thanks. I was thinking 285 rear, is that technically feasible?

We have some shitty / slipery roads here and I have issues in putting down the power properly. I wouldn't worry too much about understeering because as I said road quality is bad and first thing always to happen is rear end brakes loose.

At the track I am quite happy with the stock configuration, so I can switch to that whenever needed.

What are the ZCP wheel specs?

The wheel sizes are

18" style 260
Front 8,5J ET:29
Rear 9,5J ET:23

19" Style 220
Front 8,5J ET:29
Rear 9,5J ET:23

I've been searching and searching and so far have not found any info on what the required offsets are for 18" rims on the E92 M3. Is that what the "ET" part is above?

(Why 18s? Because I'm wanting to get some 18" rims for winter tire use, and can't stand the idea of mounting those crummy looking 7-spoke "sport edition" wheels in the wheel/tire combo on Tire Rack.)

Any ideas? I'm ready to put Wintersports on my 19" ZCP wheels otherwise.
