Braking distances and lap times are better when lower; speeds, wear and grip figures when higher. A test's figures are its own: sizes, cars, surfaces and temperatures differ from one to the next, which is why the averages here are only ever of tests the two tyres shared.
Head to head in 3 tests in 2021
Each row is one published test in which both tyres ran on the same car, in the same size, on the same day. The line is the whole field, winner on the left.

Where this data comes from
Finishing positions and measurements are transcribed from each published test. A test only counts here when both tyres 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 Tyre Reviews Score rates each tyre out of 10 from every independent test result and vetted owner review we hold, so two tyres can be compared even before a test has run them together.
Who does the testing
Every test published as a Tyre Reviews test is run by Jonathan Benson, who has been testing tyres independently since 2007.
