2025 Autobild Sports Cars UUHP 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.

34.4 m +3.20 m 40 km/h
35.2 m +4.00 m 44 km/h
36.5 m +5.30 m 50 km/h

The difference between best and worst was 17% (5.3 m ≈ 1.2 Car Lengths). From 130 km/h, the Gripmax SuperGrip Pro Sport would still be travelling at 50 km/h when the Continental SportContact 7 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 25.6% (11.2 m ≈ 2.5 Car Lengths). From 130 km/h, the Gripmax SuperGrip Pro Sport would still be travelling at 59 km/h when the Continental SportContact 7 had stopped.

The difference between best and worst was 16.3% (1.3 kg / t). Over 19,000 km a year at £1.45/L, the Goodyear Eagle F1 SuperSport uses about 49 L (£72) more fuel than the Gripmax SuperGrip Pro Sport.

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.
