  • Effective Rolling Radius - an overview

    With increasing speed, the tire belt experiences a larger radial acceleration. As a result, the effective rolling radius will increase with increasing speed and increasing inflation pressure. The variation with speed is strongly dependent on the tire radial stiffness and therefore, on the tire carcass structure.

  • Loaded Radius - an overview

    The following are other definitions related to tyre radius provided in SAE J670e (1976): 1. The loaded radius, R l, is the distance from the centre of the tyre contact patch to the wheel centre measured in the wheel plane. 2. The static loaded radius is the loaded radius of a stationary tyre inflated to the normal recommended pressure. 3.
