Answer:
Larger area produces lesser pressure on the ground.
Step-by-step explanation:
Trucks carrying heavy loads use eight tires to reduce the pressure on its tyres. As the surface area increases the force/load is spread over a larger area reducing the pressure. This reduction in pressure allows the truck to move better and also protects the tyres from excessive wear and tear.
