Tire Coefficients of Friction (Mu)

stimulisRK

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.

If this is for a thought/textbook excericse, you may as well just assume something. 0.9 seems sensible.
Pneumatic tyres are funny things. The friction coefficiecnt changes hugely between different types of tyres, and conditions. Load, tyre pressures, temperatures, surface conditions, tread, all make a large difference.

So either you'll have to be more specific with the conditions of braking, or just assume a figure.
