Finally, some one _else_ who gets it...

Your car is supported by the air pressure in the tires ..equal and opposite
reactions, and all that, so..

A 2800 lbs car with say, 60% of its weight on the front axle, has 1680 lbs
on that axle, or 840 lbs per tire.
@ 32 lbs per square inch in the tire, how many square inches of patch does
it have?

840/32 = 26.25 square inches.

Wanna change its size? Change vehicle weight, or tire pressure.
Wanna change its shape? Change tire size.
Wanna change its quality? Change tire brands/models.
