The off roaders use a wide tire to have a lower PSI* so that the tire does not dig into the mud or sand as much. In some other situations wider tires are a hinderance. Big wide tires are somewhat of an affectation in some cases.
A sipe does not remove any material.
*pounds per square inch of contact patch not tire pressure, though lower tire pressure allows the tire to form to the rocks and what not)

Lmao!!! Sports cars and drag racers and anyone wanting maximum traction (in the dry, on a paved road at least) are needing the most contact surface. This includes braking, acceleration and cornering. Tires have an operating temp as well, usually the hotter the better to an extent. Watch how dragsters do a burn out before a run, nascar and circle track racers weave. It's to HEAT up the tires, not cool it.
