I'm doing a lab for school and the recommended tire pressure for my car is 32 psi. I had a 1"x1" grid and rolled the tire over it getting an area of 42 inches. The weight of th car is 3532 lbs. I received my answer by dividing the weight by the area...is this the correct formula to get the answer? Would I then divide that answer by 4 for all 4 tires?
