A Temperature Study of Pneumatic Tires During Highway Operation
Abstract
Automotive pneumatic tire and road surface temperatures are measured using infrared sensory non-contact techniques. A highway test vehicle implemented with on-board dual system temperature averaging and high speed circumferential profiling instrumentation package is described. Infrared techniques used for generating 'tire temperature histories' are discussed in terms of highway performance factors. The influencing effects of road surface and air temperature, air flow and solar load are shown. Circumferential high resolution temperature profiles are also shown for defect induced tires relative to sensing the development and location of the defect under actual highway conditions of operation. Average tread and sidewall temperatures are plotted for new and worn 2-ply and 4-ply bias-belted tires for variations of load, speed, inflation, balance and camber. A comparison is made between the temperatures generated in tires operated under highway conditions and the same tire run on the dynamometer drum tester. The results of the overall program are based on approximately 5000 miles of highway testing performed on 10 test tires of various types.
