Detailed Solution

The above statement is True.
Pressure is the force acting on the unit area of any surface. When the surface area falls, the pressure rises simultaneously, and when the surface area rises, the pressure drops. Hence, pressure is inversely proportional to the area of the cross-section. The formula of pressure is

Pressure = \frac{T h rust (force)}{area}

If the surface area is decreased, the applied pressure increases. So, to reduce the pressure applied by the trucks, the tyres used are broad in size, whereas the bicycle tyres are narrow as the pressure applied by them is already very less.
