Jeep Liberty: Treadwear - Department Of Transportation Uniform Tire Quality Grades - If You Need Consumer Assistance - Jeep Liberty Owner's ManualJeep Liberty: Treadwear

The Treadwear grade is a comparative rating, based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices, and differences in road characteristics and climate.
