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 tyres can be separated by very different margins.

Positions and gaps always refer to the full test field within each group. Selecting tyres does not recalculate rankings or change the best-in-test benchmark.

39.2 m +4.10 m 42 km/h
39.6 m +4.50 m 44 km/h

The difference between best and worst was 12.8% (4.5 m ≈ 1 Car Lengths). From 130 km/h, the Berlin Tires Summer UHP 1 would still be travelling at 44 km/h 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 101.2% (41.6 m ≈ 9.2 Car Lengths). From 130 km/h, the Landsail LS588 UHP would still be travelling at 92 km/h when the Bridgestone Potenza Sport had stopped.

The difference between best and worst was 29.4% (2.24 kg / t). Over 19,000 km a year at £1.45/L, the Vredestein Ultrac Vorti R uses about 89 L (£130) more fuel than the Landsail LS588 UHP.

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 tyre age. For comparative purposes only. Lifetime savings based on a 40,000km / 25,000 mile tread life.
