Optimizing indoor tire abrasion tests on sandpaper

Indoor tire wear tests wear out the tire and the drum surface. Tire wear machines often use sandpaper on their drums, which makes the tests less realistic. Sandpaper must be replaced regularly to accurately reproduce abrasion tests. The Euro7 regulation allows for these tests to be carried out on indoor test benches. This study develops a method based on the ETRTO method that significantly reduces the number of reference tires and measurement time.
