WEST CONSHOHOCKEN, Pa. (Feb. 12, 2009)—ASTM International has adopted as a standard a rim slip performance test for tires that has been done at the Nevada Automotive Test Center for more than 20 years.
ASTM F2803—Test Method for Evaluating Rim Slip Performance of Tires and Wheels—was developed by Subcommittee F09.20 on Vehicular Testing, part of Committee F09 on Tires.
Rim slip occurs when tire and wheel combinations are subjected to high torque inputs, with excessive rim slip happening when tire and wheel interface is less than optimal. The condition can cause improper bead seating, bead damage or additional polishing of the inside rim flange, according to Jason Whiteley, an automotive/tire test engineer at the Nevada test center and also an F09 member.
He said the new standard will help tire and wheel makers determine what effect different tire designs, wheel designs or inflation pressures have on the amount of rim slip experienced.
