2021 Motor Summer Tire Test

Compare each discipline in the tested size. See the measured result, position and gap to the best tire, 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 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.

122 ft +9 ft 21 mph
128 ft +15 ft 27 mph

The difference between best and worst was 13.3% (15 ft ≈ 1 Car Lengths). From 80 mph, the Imperial Ecosport 2 would still be travelling at 27 mph when the Continental Premium Contact 6 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 34.1% (2.25 kg / t). Over 12,000 miles a year at $3.60/gal, the Goodyear Eagle F1 Asymmetric 5 uses about 28 gal ($100) more fuel than the Pirelli Cinturato P7 Blue.

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 tire selection above.

12,000 mi
$3.60/gal
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 tire age. For comparative purposes only. Lifetime savings based on a 40,000km / 25,000 mile tread life.
