Where this data comes from
Finishing positions and measurements are transcribed from each published test. A test only counts here when both tires ran in it, so every figure was recorded on the same car, size and day as the one it is compared to.
About the TR Score
The Tire Reviews Score rates each tire out of 10 from every independent test result and vetted owner review we hold, so two tires can be compared even before a test has run them together.
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.
