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.
