Answer:

=72000 Newtons

Explanation:

Pressure=Force/Area

Thus, Force= Pressure×Area

In this scenario, the weight of the car is the force.

The total absolute pressure in the tires is :2×10⁵Pa×4=8×10⁵ Pa

The total area in contact with the ground is:0.024m²×4=0.096m²

Thus the weight of the car=(8×10⁵Pa)×0.096m²

=72000 Newtons
