2018 Auto Bild 20 inch UHP 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.

Tested size: 245/30 R20
Tyres tested: 8
Disciplines: 7

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.

Set my vehicle consumption

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.
