just to extend on what Norbie was saying..

The size of the contact patch doesn't change when choosing a wider tyre.. *at the same pressures*. It just gets shorter, ie:

|||
|||
|||
|||

||||
||||
||||


This provides better cornering because the size of the lateral contact patch is greater, giving more sideways grip

It also explains why wide tyres tramline (follow imperfections in the road), because their longitudinal grip is less than a narrow tyre which tracks nicely.

The only way to increase your contact patch is to lower the tyre pressure, as seen in all dragracing and 4WD beach driving.
