Owner ratings are submitted through the review form on this site, naming the tyre, the size and the distance covered, and are checked by hand before publication. Test results come from independent published tyre tests indexed by size, and label values from the EU EPREL database.
The Tyre Reviews Score rates each tyre 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.
Every test published as a Tyre Reviews test is run by Jonathan Benson, who has been testing tyres independently since 2007.
