Assuming 9.5j & not a ridiculous offset then no problem at all , lots of clearance with increased wheel protection & ride comfort .
I always go 255 35 on 19s , no reason not to
Mr Wilks, what size do you suggest for the fronts?
On style 326 ?
3 ZMRs

Yes. Thinking of going up on the front like the back for a more comfort and match the rolling circumference a little more. However, some have had rubbing issues at the front and so I'm confused as to what tyre size to order.

How about 225/40? Or do you recommend keeping the front the same and just going up on the profile at the rear?

I fitted 225 40 19 to a set of 8.5j wheels on a 23i but only to reduce arch gap without lowering springs , on Msport with 326 8j id say 235 35 was the max you would want on front without looking over tyred

Thanks buddy. Always appreciate your input.

Has anyone else here fitted 235 35 on 19" 326 wheels without any rubbing? If so, is your car lowered and what brand of tyres are you running?

I fitted 255/35 rear and 235/35 fronts on my 35is a couple of months ago, no problems and 100% nicer car to drive, obviously non runflats Goodyear Asymmetric 3s

Ive just changed my rears over to 255/35/19 (from 255/30/19) and the car seems fine, don't seem to feel every bump in the road. I did check with my local BMW dealer when the car was in for the recall and they said it was fine. Went for Goodyear eagle F1's as they had a better rating for performance in the wet compared to the Pirellis I have on at present £580 to change all four tyres 255/35/19 r + 225/35/19 f

I've heard good things about that tyre. Goodyears are known for a slightly softer sidewall too, so should help the ride comfort. Are you on standard springs, msport or is is lowered?

As above, wondering what springs you're on at the moment? Thanks
