M4 wheels styling M513 fits 1M? 255 40 18 275 40 18

[MDMA 135i]

Hello, i can bought m4 new rims with new pilot super sport on them for very good price.

Front 9jx18 et 29 255 40 18
Rear 10jx18 et40 275 40 18

Are these m4 tyre specs should be ok for 1M?

Rear should be no problem on tire width, may want a spacer.

Fronts are 0.2" larger diameter than stock, and obviously a little wider also, similar to the 255/35/19's many run up front. Offset is pretty close to stock. You may rub (probably not) if you have not upgraded the front fender liners, but they are cheap to buy and easy to swap yourself.

Let us know how it fits, and post pics!

Thank you. Wheels will come for few days. I will post pictures. Actually i have a 135i but with complete front and rear m3 subframe swap, including m3 steering rack and me brakes. I will also make this week front and rear 1M conversion. I supposed that with 255 275 tyres my speed will show wrong. I hope that i will not have problem with dsc.

Btw i already bought revised fender liners.

Didn't notice the car . . . I have no idea if those will fit. There is also the fender difference, so not possible to compare.

I did last year with my M2 wheels (same tires size as the 1M).

Perfect fit in the front.
At the rear, the M2/M4 wheels offset is narrower compared to 1M wheels ! For example, when I install the 1M wheels on my M2, it's too wide (rubbing the fender).
