Check your physics book....

A wider tire does NOT give you a larger contact patch, merely a WIDER, shorter one. Contact patch size has to do with vehicle weight and PSI, nothing to do with how wide your tires are.

If you have a 255 and a 195 tire, with the same pressure, they will both have the same SIZE (not shape) contact patch on the ground.

Common misconception. Wider tire does NOT equal larger contact patch (for a given pressure). For cornering however, the wider contact patch will indeed perform better than the longer one...
