Width matters not diameter, ideally the smaller wheels requires less energy to spin it and keep it spinning.

M3 GT uses a 300-60/18 tire. Might be a rule for ALMS, but all ALMS GT cars use 18s.

same with the F430 GT

baffles me that the new F458 has 20's. Lots of manufactuers use 19s b/c of looks or b/c they need to fit carbon ceramic brakes on the cars.
