Tire fitment and size question

Hi , I just got my HREs installed on the car and compared to the OEM 19s wheels, the tires seem much stretched in the rear..
Does this look like the rear wheels should be paired with wider tires??I used to run 295 in the rear on E92, it worked fine, guess i should also go 295 for the M4 too ?
Here's the front , the tire fits fine with a flatter sidewall

However, the rear tire seems much more stretched than it was on stock wheels.

Not very sure but i think it's 10.5""? I used to put it on my e92 and used 295 in the rear with no rubbing. However, i talked to a tirerack guy and they said 295/35/19 will probably have a rubbing issue...

The offsets on the E9x M3 Rears are a bit lower than the F8x. By default your HRE's would have a lower rear offset than a set they'd configure for the new M3/M4

For reference :

E9x ZCP 19" Wheels (Competition)

Front : 19x9 ET31
Rear : 19x10 ET25

F8x 19" Wheels :

Front : 19x9 ET29
Rear : 19x10 ET40

As your TireRack fellow said, you might not be able to go wider without rubbing. The more aggressive (Lower) offset on the E9x rears push those wheels out and if you bottom out your suspension, it might take half your fender with it if your tire is too wide.

See if you can find your build sheet from your HRE order, and let me know the offset. I should be able to offer some more helpful advice then

thanks for the reply! I will ask HRE about it and get back to you
