Standard Guide for Preparing Artificially Worn Passenger and Light Truck Tires for Testing

Importancia y uso:

5.1 Tires having reduced groove depth are required in some tire tests to determine changes in performance as a tire wears in service. This guide describes the preparation of artificially worn tires. This guide is not meant to replace the development of worn tires through over-the-road travel when naturally worn tires are required. Further refinements of these techniques may be made with increased field experience.

5.2 The amount of tread rubber to be removed (groove depth reduction) and the final surface texture are selected according to the requirements of a particular testing program.

5.3 The type of test program determines the actual tolerance necessary on the final groove depth. For example, snow traction will require very close control of the final groove depth while vehicle handling tests can accommodate a wider tolerance on the final groove depth.
