Question

Trucks and buses have double tyres in their rear end Explain

Deepak Kumar · Accepted Answer

Dear
Student,

Buses
and trucks have double wheels at the back because these are heavy
vehicles with most of the loads resting towards the back Also, the
engine that drives the vehicle is attached to the back wheels so
the double back wheels provides better hold on the ground Double
wheels are not used in the front since that would make the steering
uncomfortable
