I have recently replaced my 16'' stock rim to 18X8 rims and I am experiencing some drift. My steering wheel wanders and drifts towards left by itself and it's hard to control. It is quite rapid and espeicially when I put on my brakes. I have already taken my car to Bob Jane twice for wheel allignment but they said the rims may be too wide for my car.

Does anyone have the same rim size as mine or bigger and experience the same? BY the way my tyre is Kumho 225/40. Any tips?
