I do believe you are. You are not taking into account the weight of the vehicle. If you have tyre that is 185 wide, the car is putting so much pressure per square cm. if you increase this to 215, you have have the same weight pressing down over a greater width. So if you assume the same pressure and compound, you will have no more grip than with the 215, than you will with the 185. Think about it like this; does the tyre sit perfectly round? No, the part in contact with the round is actually flat. Edit: Also assuming weight of vehicle doesn't change either. [Updated on: Fri, 03 December 2004 05:09] [Report message to a moderator]
