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 tires can be separated by very different margins.
Positions and gaps always refer to the full test field within each group. Selecting tires does not recalculate rankings or change the best-in-test benchmark.

|---|---|---|---|
| 108 ft | Best | 0 mph | |
| 108 ft | 0 ft | 6 mph | |
| 109 ft | +1 ft | 9 mph | |

| 116 ft | +8 ft | 21 mph | |
| 116 ft | +8 ft | 21 mph | |
| 117 ft | +9 ft | 23 mph |
The difference between best and worst was 8.8% (9 ft ≈ 0.6 Car Lengths). From 80 mph, the Westlake ZuperAce Z 007 would still be travelling at 23 mph when the Continental PremiumContact 7 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 doing 29 mpg (rolling resistance causing 20% of fuel use), fuel at €6.25 per gallon and €70 fitting per set of four. Purchase prices are from the time of the 2026 test; financing costs are excluded.

| 8.1 kg/t | +1.30 kg/t | $56 | |
| 8.2 kg/t | +1.40 kg/t | $61 |
The difference between best and worst was 20.6% (1.4 kg / t). Over 12,000 miles a year at $3.60/gal, the Tercelo Sport D1 uses about 17 gal ($61) more fuel than the Michelin Primacy 5.
