Determine the weight of the automobile?

Question

The four tires of an automobile are inflated to a gauge pressure of 153000 Pa. Each tire has an area of 0.0221 m^2 in contact with the ground.

Determine the weight of the automobile. Answer in units of N.

Answer 1

Would it make any difference if the tires were made of solid rubber?

Ironically the number fall nicely

F=PA (153 000 x 4 x 0.0221)= 13525 N

Actually the weight of the automobile =
W=4 (P2-P1)(A)
W - weight of the automobile
P2 -pressure in tires with automobile load
P1 -pressure no load
A- internal area of the tire
