Every measurement, side by side
Averages of the figures both tires posted in the same tests. The gap is the average of each test's own gap, so figures from different cars and years are never mixed. Wins count the tests in which each tire did better.

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 tires shared.
Head to head in 2 tests, 2023 to 2025
Each row is one published test in which both tires ran on the same car, in the same size, on the same day. The line is the whole field, winner on the left.

Your review is the part of this page no test can supply: how the tire wore, how it aged, what it was like in the rain in year three. It takes about five minutes.
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.
