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 tires can be separated by very different margins.
Positions and gaps always refer to the full test field within each group. Selecting tires does not recalculate rankings or change the best-in-test benchmark.

| 116 ft | +3 ft | 15 mph | |
| 119 ft | +6 ft | 18 mph |
The difference between best and worst was 5.5% (6 ft ≈ 0.4 Car Lengths). From 80 mph, the Dunlop SportMaxx RT 2 would still be travelling at 18 mph when the Michelin Pilot Sport 4 had stopped.
Residual speed is calculated from the measured braking distances, assuming constant deceleration; it is not a separate measurement.
