Review Your Tires

Where this data comes from

Owner ratings are submitted through the review form on this site, naming the tire, the size and the distance covered, and are checked by hand before publication. Test results come from independent published tire tests indexed by size, and label values from the EU EPREL database.

About the TR Score

The Tire Reviews Score rates each tire out of 10 using independent test results and the full body of owner reviews, so you can check a car-specific ranking against the wider evidence.

Who does the testing

Every test published as a Tire Reviews test is run by Jonathan Benson, who has been testing tires independently since 2007.
