What is the rolling resistance of my tires?

    The coefficient of rolling resistance b, which has the dimension of length, is approximately (due to the small-angle approximation of {cos θ=1} equal to the value of the rolling resistance force times the radius of the wheel divided by the wheel load.

    =>Calculating rolling resistance:

    This equation is used to calculate the force of rolling resistance from each tyre:

    FRR = CRR x weight

    FRR is the rolling resistance force.

    CRR is the coefficient of rolling resistance (a number used to rate each tyre at a given pressure),

    weight is the force due to gravity being exerted on each tyre {= mass (kilograms) x 9.8}.
