Weight of car = 8000 N 
Weight on each tyre of car = 8000/4 = 2000 N 
 
Area of one tyre = 150 cm2 
 
Pressure exerted by one tyre on ground = Force/ Area = 2000/150 N/cm2 = 13.33 N/cm2

We say that pressure is defined as the amount of force exerted on an unit area and if the area is decreased, pressure increases For example an iron nail would be applying more pressure than any other thing let's say 100 N per m square but the question is an iron nail doesn't cover an area of m square so why do we say 100 N per m square
