Tire Tread Temperatures in Actual Contact Areas

Abstract

Abstract This report treats the temperature in an actual contact area between the pavement and the tread of a cornering tire. A method to compute the temperature by using Jaeger's formula for a moving heat source is proposed. Additionally, a temperature measurement was conducted. The computed value is consistent with the measured value. The computed results for various pavement parameters show that the actual contact area size and pavement thermal diffusivity significantly affect the temperature, and that the distribution of tire tread temperature around the actual contact area varies considerably along the slip direction of the tread.
