So I’ve bought some 788M alloys with pilot super sports from an M2 comp
And I want to fit them on my 335D xdrive



Front 245/35/19
Rears 265/35/19

Are they ok for the xdrive system? I’ve heard about this 1% rule
I don’t fancy breaking anything.

The car came with 400M alloys

Front 225/40/18
Rear 255/40/18


The difference between the two sets of similar being just the widths are different

Can someone help me out?

245/35/19 front + 265/35/19 rear is not ok for x-drive

i recommend one of the 3 size combos below for x-drive with M wheels:

235/40/19 + 265/35/19, front is a bit stretched, best tire size combo imo
255/35/19 + 265/35/19, at limit for x-drive, front shoulder is poke side of flush
245/35/19 + 285/30/19, lowering required due to increased wheel gaps
