Surface Temperature of Running Tires Using Infrared Scanning 700475

An infrared line scanning system has been used to measure surface temperatures of automobile tires under operating conditions. A designed experiment was employed to demonstrate statistically the individual and interaction effects on tire temperature profiles of changes in tire speed, inflation pressure, and wheel load. These effects are different at different radial positions on a given tire and are quite dependent on tire construction, as illustrated by application to bias, belted-bias, and radial tires of comparable sizes.
