Weight distribution.
because the wheels are broard
so that pressure will decrease and road will not sink
trucks have broad wheel because so that it reduces pressure and the tyres dont burst.
Weight distribution. It prevents damage to roadways.
Vehicles with four wheels are cars, buses and most carriages. Some smaller trucks also have four wheels. There are bicycles as well as motorcycles with four wheels, but the vast majority of these vehicles are only two-wheeled.
They have double tyres at the rear end so that they have enough strength to carry the heavy load or the public
It is because the place through which the bus or truck is moving has a large surface area , as the tires become wider it will be easy to drive.
The rotation of the steering shaft drives the turning of the wheels, and buses and large trucks have wheels which are significantly more massive than cars' and light trucks', requiring more torque on the steering shaft to turn the wheels. The larger steering wheel gives a mechanical advantage in turning the steering shaft; a longer moment-arm from the application of force by the driver on the steering wheel results in a larger torque on the steering shaft from the same force applied.
wheels are used everyday. Cars, bikes, buses, planes and trains. Many forms of transport rely on the wheel. Shopping trollies, trucks, forklifts. Wheels allow heavy weights to roll easily and move.
