I was wondering if any of you had recently changed from 18" wheels (235/40/18 tyres) to 19" wheels (235/35/19 tyres) and could describe the difference in ride. I am considering the change but to be honest the ride is already pretty bumpy/stiff (IMO.....) Has anyone ever tried 245/35 tyres? from the measurements this adds about 4mm to the overall diameter (not enough to affect gearing and less than the normal 5/6mm tyre wear over the life of a tyre too).
