I'm having these issues since changing from Morr (19x8,19.5)235/35,265/30 to e90 m3 (19x8.5,19x9.5) 235/35&265/35
this is going crazy and undriveable. The only difference is the rear tyres are 35 series instead of 30 series.
While driving my trac control keep coming on which is impossible on dry land, turning it off doesn't help ...
Any ideas or solutions ?
