EXTENDED TIRE TESTING

A test program was performed at the Calspan Tire Research Facility (TIRF) to derive the tire force and moment characteristics of a representative sample of current passenger car tire designs. Several tire selection categories were defined to include high and low performance, standard original and after-market equipment, spacesavers, runflat, all weather, size and low rolling resistance tires. The initial test phase included a free-rolling cornering/camber test and a separate braking traction test on each of fifty tire types. Testing was performed on the flat, dry road surface. Twenty-five tires were further selected from the original fifty tire sample for additional testing to include inflation pressure variations, wet roadway, rolling resistance and combined cornering and braking traction tests on new and shaved tires. The report describes the test program details, includes summaries of test results and provides some brief observations of current tire performance characteristics.
