What is Treadwear?

It is the relative life expectancy of the tire, based on a standard test. 

For example, a 280 specification tire wears 2.8 times slower than a standard tire with a Treadwear Index of 100. 

Tire performance depends on the respective conditions of use and can vary significantly from normal values due to driving behavior, maintenance, the different characteristics of the track and the weather conditions.
