What am I missing?

ohh wow your special, get two balls of the same size, set one ball on a table, that would be the tire off the car standing upright unloaded, now take your hand and press on the second ball, the ball will absorb the pressure and compress, this is replicating a tire when its on a car and the car's weight is on the tire thus giving a larger contact patch
now on test two get a volley ball(smaller ball) and a basket ball(larger ball)
inflate both balls to the same PSI and dip the bottoms in paint
press both balls onto a large piece of paper, now press down on both balls with equal force
measure the diameter of each paint print
the result should show that the volley ball has a smaller contact patch than the basket ball, its 3rd grade science project i hope you can complete it...
you can even further the test by putting more pressure on the basket ball to resemble a higher load for larger diameter tires that are usually used on heavier cars the measure the difference in diameter vs the volleyball with less load
