Which size tyres for these wheels?

[bmwaddict]

Looking at changing my style 108s for some 18x8.5s all round, et45 front et30 rears.
Which size tyres would anyone recommend for no rubbing? Would also like as little stretch as possible.
At the moment I'm looking at something like
235/40 fronts
255/35 rears

Car is running standard height.

Thanks in advance.

I'd go 235/40 all round.

Found the same wheels in et45 all round so should be able to use 235 front 255 rear?

Not if you want stretch.

As I said I want as little stretch as possible.
The rears should only poke out 7mm more so I'm hoping to stay with 255s.
The fronts wil poke out 6.5mm more, I'm wondering how big a tyre can I get away with without rubbing issues.

Love your coupe btw

Ah apologies! I mis-read!

235 should give you what you want on the front. I believe some have reported of rubbing issues with 255 on the front

Many thanks.
