Category scores are percentiles among tires of the same season and class: 90 means this tire out-performs 90% of them, measured across every test we hold, not only the ones it appeared in.
Every measurement, side by side
Both tires' figures from the one test that ran them together, on the same car, in the same size, on the same day. The bar grows towards the tire that did better.
| Measurement | Grip Master 4S | Gap | RGAS02 |
|---|---|---|---|
| Dry Grip Master 4S ahead | |||
| Dry Braking ft | 125 | 0.8% | 126 |
| Wet Grip Master 4S ahead | |||
| Wet Braking ft | 156 | 9.7% | 173 |
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 1 test in 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.

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.
