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.

Dry
2Dry Braking
Dry braking in feet (62 - 0 mph)
Lower is better ↓| Position / Tire | Result | Gap to best | Residual speed |
|---|---|---|---|
| 102 ft | Best | 0 mph | |
| 108 ft | +6 ft | 19 mph | |
| 109 ft | +7 ft | 19 mph | |
| 112 ft | +10 ft | 23 mph | |
| 113 ft | +11 ft | 24 mph | |
| 115 ft | +13 ft | 27 mph | |
| 120 ft | +18 ft | 30 mph |
The difference between best and worst was 17% (18 ft ≈ 1.2 Car Lengths). From 80 mph, the Gripmax SuperGrip Pro Sport would still be travelling at 30 mph when the Continental SportContact 7 had stopped.
Residual speed is calculated from the measured braking distances, assuming constant deceleration; it is not a separate measurement.
