Performance profile
10 measurements from the 7 shared tests, each tyre shown as its share of the better figure in every test.
Where each is furthest ahead
EfficientGrip Performance 2
Dynaxer HP4
Point at or tap any spoke for both tyres' figures.
In each test the better of the two figures counts as 100% and the other as its share of it, so a 36 m stop against 34.2 m is 95%; each spoke averages the shared tests that recorded it. The scale stops at 94%: a point further in sits on the hub's edge, hollow. 4 measurements recorded in only one shared test are left off; every measurement is in the table further down.

Every measurement, side by side
Averages of the figures both tyres 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 tyre 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 tyres shared.
Head to head in 7 tests, 2021 to 2024
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.
