2025 Die Reifentester UHP Summer Tyre Test

Compare each discipline in the tested size. See the measured result, position and gap to the best tyre, then read the verdict for the trade-offs behind the finishing order.

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.

34.97 m +1.35 m 26 km/h
35 m +1.38 m 26 km/h
35.62 m +2.00 m 31 km/h

The difference between best and worst was 5.9% (2 m ≈ 0.4 Car Lengths). From 130 km/h, the Vredestein Ultrac Pro would still be travelling at 31 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 16.3% (3.75 m ≈ 0.8 Car Lengths). From 130 km/h, the Vredestein Ultrac Pro would still be travelling at 49 km/h when the Kumho Ecsta Sport PS72 had stopped.

The difference between best and worst was 21.9% (1.94 kg / t). Over 19,000 km a year at £1.45/L, the Goodyear Eagle F1 SuperSport uses about 67 L (£97) 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 tyre selection above.

19,000 km
£1.45/L
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.
