# Why Front Wheels Wear Out?

Perhaps you have noticed the wheels of some carts – the front ones are smaller than the rear ones. Why do the front axles wear out faster than the rear?

When a cylinder rolls on a surface the force resisting motion is termed rolling friction. Rolling friction is generally considerably less than sliding friction. If W is the weight of the cylinder converted to force, or the force between the cylinder and the flat surface, and R is radius of the cylinder and F is the force required to overcome the rolling friction then.

center>F = f x W/R

f is the coefficient of rolling friction and has the same unit of length as the radius R -in the example below m (metres)

force require to overcome from rolling friction is inveresly prepotional to radius of any rolling element,so front wheel will wear out more den rear wheel…

maybe becoz the load is mainly on the rear wheel and so is the frictional wear more in rear wheel.
