Subaru Legacy BN/BS (2015-2019) Owners Manual: Treadwear

Subaru Legacy BN/BS (2015-2019) Owners Manual / Consumer information and Reporting safety defects / Uniform tire quality grading standards / 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 (1- 1/2) times as well on the government course as a tire graded 100.
