Q. Can I change the 18in tyres on my Ford S-Max Titanium X Sport to get a softer ride?
A. Reducing the wheel size and fitting a higher-profile tyre will help, though the overall diameter of the wheel-and-tyre assembly must stay the same.
You could go down to a 16in wheel with 215/60 tyres. The 215 figure refers to the width of the tyre in millimetres, and 60 is the tyre’s aspect ratio: the height (from the wheel rim to the top of the tyre) expressed as a percentage of the width. Anything under 50% is considered low profile, and the lower the profile, the firmer the ride.
These tyres will be about 10% cheaper than your current ones.
