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.

| 39.4 m | +4.60 m | 44 km/h | |
| 39.5 m | +4.70 m | 45 km/h |
The difference between best and worst was 13.5% (4.7 m ≈ 1 Car Lengths). From 130 km/h, the Double Coin DC 100 would still be travelling at 45 km/h when the Kumho Ecsta PS71 had stopped.
Residual speed is calculated from the measured braking distances, assuming constant deceleration; it is not a separate measurement.
