Range Rover: 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 (1½) times as well on the government course as a tire graded 100.

NOTICE

If treadwear is uneven across the tire, or a tire wears excessively, the vehicle should be checked by your Land Rover Retailer/ Authorized Repairer as soon as possible.

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.

When the tread has worn down to approximately 2 mm, wear indicators start to

When the tread has worn down to approximately 2 mm, wear indicators start to appear at the surface of the tread pattern. This produces a continuous band of rubber across the tread as a visual indicator.

WARNING

Wear indicators show the minimum tread depth recommended by the manufacturers. Tires which have worn to this point will have reduced grip and poor water displacement characteristics.

Note: Local legislation may determine a greater tread depth to that shown by the tire wear indicators. It remains the driver’s responsibility to ensure the tread depth meets the local legal requirements. Do not rely on the tread depth indicators alone.

Uniform tire quality grading

Quality grades can be found where applicable on the tire sidewall between the tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A. In addition to the mar ...

Traction

The traction grades, from highest to lowest, are AA, A, B, and C. The grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government ...
