Re: Brecoflex Treads
When it comes to CoF, measuring it yourself is really the only way to do it. Do not trust numbers you see online from manufacturers - we have seen actual CoF vary by 50% or more on multiple occasions.
The interaction of a wheel with a carpeted surface is complex, and Coulomb friction is but one of the factors. Play around a bit with a few of the common FRC tread materials in a number of configurations (play with the diameter and width of the wheels), and you will find that a 1.3 CoF for something like Roughtop is, at best, a nominal value.
