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.

36.9 m +3.90 m 42 km/h

The difference between best and worst was 11.8% (3.9 m ≈ 0.9 Car Lengths). From 130 km/h, the Mastersteel Super Sport 2 would still be travelling at 42 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 60.8% (8.08 Price/1000). Over 40,000 km the cheapest tyre to own (Goodyear Eagle F1 Asymmetric 6) works out €471 cheaper than the most expensive (Bridgestone Potenza Sport).

How this is calculated

Assumes a typical car using 8 l/100km (with rolling resistance causing 20% of fuel use), fuel at €1.65 per litre and €70 fitting per set of four. Purchase prices are from the time of the 2025 test; financing costs are excluded.

10.15 kg/t +2.80 kg/t £168

The difference between best and worst was 38.1% (2.8 kg / t). Over 19,000 km a year at £1.45/L, the Bridgestone Potenza Sport uses about 116 L (£168) more fuel than the Mastersteel Super Sport 2.

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.
