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.

| 36.1 m | +3.10 m | 38 km/h | |
| 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.

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.
