Which tyre size?

Hi all,

getting some new wheels for the 640D coupe which are slightly wider than the OEM 20s...

Stock
8.5 x 20 ET33
9 x 20 ET44

New:
9J x 20 ET 32
10J x 20 ET 34


What tyre size would be best to go for that isn't stretched or anything silly, maybe 255/35 front and 285/30 rears?

Cheers

Edit; did some research and...

Maybe I shouldn't get new wheels and stick with the 373ms!....LOL

The 343M Forged wheel is 11.2 Kg for the front wheel and 11.7Kg for the rear.

The 601M Light Alloy wheel is 13.78Kg for the front and 13.9Kg for the rear

343m and 601m are both 20x9 32mm and 20x10 34mm in M5 fitment

The 8.5" 33mm and 9" 44mm spec you list is for the standard non-M 6 series wheels.

So if you've bought genuine M5 343m or 601m wheels they are the same fitment and will fit the arches much better than stock wheels

ah 5hit, sorry mate I meant to say 373M which I think are around 15kg each

I think I can run the stock tyres 245 front and 275 rear but not sure what sort of stretch they will give, want some rim protection which i think PS4s have anyway.

If I get 255/35 front and 285/30 rears will they rub with the car lowered on H&R springs?
