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 | All-Terrain T/A KO3 | Gap | Encounter AT2 |
|---|---|---|---|
| Snow All-Terrain T/A KO3 ahead | |||
| Snow Braking ft | 72 | 6.2% | 77 |
| Snow Traction ft | 46 | 9.5% | 42 |
| Subj. Snow Handling pts | 5 | 30.5% | 3.83 |
| Ice Encounter AT2 ahead | |||
| Ice Braking ft | 53 | 11.2% | 47 |
| Ice Traction s | 6.23 | 2.4% | 6.08 |
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.

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 Tyre 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 Tyre Reviews test is run by Jonathan Benson, who has been testing tires independently since 2007.
