Hey everyone,

Car: BMW m340i xDrive, adaptive suspension.

I am considering buying a set of staggered 18" 790M wheels with the following sizes:

Front: 7.5Х18 ЕТ25 5Х112 66.6
Rear: 8.5Х18 ЕТ40 5Х112 66.6

I see that the OEM spec is 225/45/18 x 255/40/18.

Do you think it would be possible and a good idea to fit 235/45/18 (Front) x 265/40/18 (Rear)? Would there be any difficulty in getting these on at a tire shop and are there any risks using it in that setup, at all?

My idea is to improve the width & grip and gain a little more sidewall for comfort and tyre & rim protection.

Thanks!
