Read the measurements, not just the rank
Lower is better for braking distances and lap times; higher is better for subjective scores and aquaplaning speed. Bars start at zero. Read the gap alongside the position: adjacent tyres can be separated by very different margins.
Positions and gaps always refer to the full test field within each group. Selecting tyres does not recalculate rankings or change the best-in-test benchmark.

Lower is better ↓| Position / Tyre | Result | Gap to best | Residual speed |
|---|---|---|---|
| 32.7 m | Best | 0 km/h | |
| 33.3 m | +0.60 m | 17 km/h | |
| 33.4 m | +0.70 m | 19 km/h | |
| 34.1 m | +1.40 m | 26 km/h | |
| 34.4 m | +1.70 m | 29 km/h | |
| 35 m | +2.30 m | 33 km/h | |
| 35.5 m | +2.80 m | 37 km/h | |
| 36.1 m | +3.40 m | 40 km/h | |
| 36.6 m | +3.90 m | 42 km/h | |
| 37.1 m | +4.40 m | 45 km/h | |
| 37.4 m | +4.70 m | 46 km/h | |
| 37.9 m | +5.20 m | 48 km/h | |
| 38.7 m | +6.00 m | 51 km/h | |
| 38.8 m | +6.10 m | 52 km/h | |
| 38.9 m | +6.20 m | 52 km/h | |
| 39.1 m | +6.40 m | 53 km/h | |
| 41.2 m | +8.50 m | 59 km/h |
The difference between best and worst was 26% (8.5 m ≈ 1.9 Car Lengths). From 130 km/h, the Firestone RoadHawk would still be travelling at 59 km/h when the Semperit Speed Life 3 had stopped.
Residual speed is calculated from the measured braking distances, assuming constant deceleration; it is not a separate measurement.
