I would appreciate your comments on the wheels fitted to my car. It's a two-year-old Signum with the 2.8 turbo engine. Nice car and cheap to buy thanks to the enormous depreciation. I find it very hard over the bumps though and it jars on every pothole. The tyres will need replacing soon and rather than fit 235/35/19, as at present, I wonder about fitting, say, 17" alloy wheels and higher profile tyres. Would this give a softer ride do you think? The money saved on buying smaller, cheaper tyres would just about cover the cost of new wheels.
