I dont really understand what you mean? I would think that wider tyres would have more rubber on the road?
I was looking for the best compromise, in a road wheel/tyre combo. I think that the stock r33 wheels are quite heavy (21kg) and not that wide (6.5inch). So was even thinking of moving to a light weight wider rim. Just dont know what is the best package. Money spent on just the tyres and keep the r33 rims, or moving to a light weight rim, wider, but less quality tyres.
R32 gtr rims good compromise?
