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.

2Dry Braking
Dry braking in feet (62 - 0 mph)
Lower is better ↓| Position / Tire | Result | Gap to best | Residual speed |
|---|---|---|---|
| 108 ft | Best | 0 mph | |
| 108 ft | 0 ft | 4 mph | |
| 109 ft | +1 ft | 9 mph | |
| 110 ft | +2 ft | 12 mph | |

| 112 ft | +4 ft | 16 mph | |
| 113 ft | +5 ft | 16 mph | |
| 114 ft | +6 ft | 19 mph |
The difference between best and worst was 5.8% (6 ft ≈ 0.4 Car Lengths). From 80 mph, the Bridgestone Turanza 6 would still be travelling at 19 mph when the Continental PremiumContact 7 had stopped.
Residual speed is calculated from the measured braking distances, assuming constant deceleration; it is not a separate measurement.
