which has bigger contact area?

RustyRatRod said

Which tire has the best contact area "WHEN"? Tire contact patches CHANGE as the car applies torque to them, ESPECIALLY drag tires that are DESIGNED to do so. So, the only real way to test them against each other is at the strip. Since the one with the smaller static contact patch may well be the one with the biggest contact patch when power is applied.

I was ASSuming we were talking about contact patch with the same sized wheel and such and that we are talking about at the launch when the chassis and suspension are loading the tire as hard as it will be in the run.

Ideally, you only want the contact patch to be as big as possible at the hit. In 20-30 feet or so you want the tire getting off the wrinkles. Take a lot of power to drive the tires when they are wrinkled.
