Do any of you know just a general range of friction coefficients for tires? I'm working out some braking problems, but can't really find anything searching online.
Tire coefficients of friction (Mu) refer to the measurement of the grip or traction that a tire has on the road surface. It is an important factor in determining a vehicle's handling and braking performance.
Tire coefficient of friction (Mu) is typically measured using a device called a dynamometer, which applies a force to a stationary tire and measures the resulting frictional force. This measurement is then compared to the weight of the vehicle to determine the Mu value.
The coefficient of friction of a tire is affected by various factors such as the type of tire, road surface conditions, air pressure, and temperature. A tire with a softer compound and a larger contact area will generally have a higher Mu value.
The tread pattern of a tire plays a significant role in its coefficient of friction. A tire with a deep and aggressive tread pattern will have a higher Mu value, providing better grip on wet or slippery surfaces. On the other hand, a worn-out tire with a smooth tread will have a lower Mu value and may increase the risk of skidding.
Maintaining the correct tire pressure is crucial for achieving optimal Mu and ensuring safe driving. Under-inflated tires have a smaller contact area, which can decrease the Mu value and reduce traction. Over-inflated tires, on the other hand, have a smaller contact patch, leading to a higher Mu value and reduced handling and braking performance.
