THE EFFECT OF OPERATING CONDITIONS ON THE SKID PERFORMANCE OF TIRES

This paper presents the results of a test program on the skid performance of tires. The program was conducted under Contract DOT-HS-205-2-238 from the Department of Transportation, National Highway Traffic Safety Administration. Effects of the following variables were evaluated: tire load; tire inflation pressure, road speed and surface water depth. An ASTM type control tire and a production bias belted tire were used in the tests. Both peak and locked wheel coefficients of friction were measured using two skid trailers. All tests were run on a wet surface with either the skid trailer's onboard watering system spreading 0.51 mm (0.02 in.) of water on the test track or sprinklers flooding the track surface to a depth of 3.05 mm (0.12 in). Load, speed, and inflation were varied over a range of three values. Two surfaces were used, SN 35 plus or minus 5 concrete and SN 60 plus or Minus 5 asphalt. Of the variables tested, load and inflation had the least effect on traction over the range which they were varied. Speed and water depth interacted, causing a significant decrease in skid coefficients with an increase in both parameters. /Author/
