On driving the scooter for a long time, the air pressure in the tyres slightly increases. Why ?

Air pressure in a car tyre increase during. Explain.

When air is pumped into a cycle tyre, the volume and pressure of the air in the tyre, both are increased. What about Boyle's law in this case?

When air is pumped into a cycle tyre the volume and pressure of the air in the tyre both are increased. What about Bouyle's law in this case?

Consider a cycle tyre being filled with air by a pump. Let V be the volume of the tyre (fixed) and at each stroke of the pump DeltaV(lt lt V) of air is transferred to the tube adiabatically . What is the work done when the pressure in the tube is increased from P_(1) to P_(2) ?

The weight of a rider, driving scooter is assumed to be evenly distributed on both the tyres.The area of contact of each type with the ground is 10cm^(2) . If the pressure inside the tyres is 3 bar, find the mass of the rider (g=10ms^(-2))
