Will 235/50/18 square fit Z3 1.9?

[kyrix1st]

Thinking of running this size square to share (lol) with my M3.

Wheel offset is 35, 8j. I've run 235/45/17 square on Z3 before so I know they don't rub horizontally, but I am unsure about 235/50/18
as it increases diameter by a mega 2.3 inches.

Any experience?

Do you enjoy that size on your m3?

Have not tried. I didn't feel the need for winter tires until now.

The short answer is no, 235/50R18 won't fit. The long answer is they will fit fine if you never plan on actually driving.

You are right. My E92 has stock suspension i.e. up to 265/35/18 front without rubbing, thus will definitely rub on 235/50/18.

I am thinking of going 245/40/18 or 235/40/18. My Z3 has camber plates&coilovers and has quite a bit of space left on 205/55/16 RS4 on so this may work just fine.
ET goes from 44 to 35 so I only have to make sure ~18(+9)mm to the outer fender works.
