Coefficient of friction

The term “friction coefficient” is defined as the maximum frictional force that be incurred between a tire that rolls on a road surface divided by the weight that rests on that tire. The calculation formula is:

μ (coefficient of friction) = Ff (frictional Force) / N (weight or normal loading on the surface)
or
Maximum available Friction Force = Friction coefficient x Normal charging on the wheel level

Therefore, handling of a car on a dry road surface will depend mainly on the nature of the surfaces and the weight of the car. On a wet roads, other factors (such as the state and tire profile) should be considered.

As the car accelerates or brakes quickly or it enters the turn at higher speeds will require higher traction forces generated by the tire-road combination. The combination tire-road will cause these forces in the maximum limit of the friction force (never above).
