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 Braking

Dry braking in feet (62 - 0 mph)

Lower is better ↓

114 ft +4 ft 14 mph
115 ft +5 ft 16 mph
115 ft +5 ft 16 mph
117 ft +7 ft 19 mph

The difference between best and worst was 5.9% (7 ft ≈ 0.4 Car Lengths). From 80 mph, the Vredestein Ultrac Pro would still be travelling at 19 mph when the Bridgestone Potenza Sport had stopped.

Residual speed is calculated from the measured braking distances, assuming constant deceleration; it is not a separate measurement.

The difference between best and worst was 21.9% (1.94 kg / t). Over 12,000 miles a year at $3.60/gal, the Goodyear Eagle F1 SuperSport uses about 18 gal ($64) more fuel than the Michelin Pilot Sport 5.

Adjust the assumptions

Calculated estimates, not additional measurements. Use the controls to explore the assumptions. These calculators use the full test field, independently of your tire selection above.

12,000 mi
$3.60/gal
Estimates based on typical driving conditions. Rolling resistance accounts for approximately 20% of IC vehicle fuel consumption and 25% of EV energy consumption. Actual savings vary based on driving style, vehicle weight, road conditions, and tire age. For comparative purposes only. Lifetime savings based on a 40,000km / 25,000 mile tread life.
