MEASUREMENT METHOD FOR COMPARING VARIOUS ROAD SURFACES' WEAR ON AUTOMOBILE TIRES (MAETMETODIK FOER ATT JAEMFOERA OLIKA VAEGYTORS SLITVERKAN PA BILDAECK)
Investigations show that the type of surface used on roadways has a considerable impact on the amount of wear and tear experienced by automobile tires. So far, however, it is impossible to determine whether the macrotexture of the microtexture of the road's surface is primarily responsible for tire wear. For this reason, investigations should continue. Most previous studies have been conducted using automobiles traveling over predetermined stretches of road. Tire wear is then measured after 6,000 km of driving. This is a time-consuming and expensive method, which is unacceptable for extensive studies. The National Road and Traffic Safety Institute proposes a new method of studying tire wear employing a specially made single-axle test vehicle to be towed by a passenger car. The two wheels on the test vehicle can be placed in a series of fixed, but adjustable toe-in or toe-out positions at a maximum angle of 15 degrees. It is hoped that 12,000 km of driving can be simulated over a stretch of less than 50 km. Test results will be compared to long-distance driving tests to confirm the validity of the new method.
