Subaru Outback (BR): 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. 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.

Tire inspection
Check on a daily basis that the tires are free from serious damage, nails, and
stones. At the same time, check the tires for abnormal wear.
Contact your SUBARU dealer immediately if you find any problem.

Determining compatibility of tire and vehicle load capacities
The sum of four tires’ maximum load ratings must exceed the maximum loaded vehicle
weight (“GVWR”). In addition, sum of the maximum load ratings of two front tires
and of two rear tires must exceed each axle’s maximum loaded capacity (“GAWR”).
