lol this is a big bug of mine, i HATE...absolutely cannot stand !! seeing any car that is relatively performance oriented on skinny tyres, i have 255's and i still think theyre too narrow haha, but they do look good from behind. aside from the better traction i think wider tyres give you more road presence, make your car look more beasty ...if he wants thin tyres tell him to stick to a bike
p.s. to whoever was talking about in the wet thinner is better, im sure thats only to a certain extent, would have more to do with tread right ?
