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
1Dry Braking
Dry braking in feet (62 - 6 mph)
Lower is better ↓| Position / Tire | Result | Gap to best | Residual speed |
|---|---|---|---|
| 129 ft | Best | 0 mph | |
| 129 ft | 0 ft | 4 mph | |
| 130 ft | +1 ft | 8 mph | |
| 132 ft | +3 ft | 12 mph | |
| 133 ft | +4 ft | 14 mph | |
| 133 ft | +4 ft | 15 mph |
The difference between best and worst was 3.6% (4 ft ≈ 0.3 Car Lengths). From 80 mph, the Bridgestone Blizzak 6 would still be travelling at 15 mph when the Dynamo Winter Sport had stopped.
Residual speed is calculated from the measured braking distances, assuming constant deceleration; it is not a separate measurement.
Wet
