Dunlop Winter Sport 5 SUV

Fuel efficiency is a measure of the tyre's rolling resistance. A tyre with low rolling resistance is fuel efficient because it requires less energy to roll. Fuel efficiency is rated from A (highest rating) to E (lowest rating).

Wet grip measures the braking ability of the tyre on wet surfaces. Wet grip is rated from A (shortest stopping distance) to E (longest stopping distance).

Measures the tyre's noise level outside the vehicle in decibels. The noise class is rated from A (quiet) to C (loud).

There are two new options for including an additional icon. The snow tyre icon shows, if a tyre is suitable for severe snow conditions. It bears a three-peak mountain snowflake symbol (3PMSF) that is incorporated in the sidewall of such tyres. The pictogram is granted by measuring the braking distance of a car from 25 mph on compacted snow or by measuring the traction force of a tyre. For a truck, the pictogram is granted by measuring the acceleration performance of a tyre. Snow grip performance in general is tested in accordance with Annex 7 to UNECE Regulation No 117. The regulation describes in detail such factors as test surface, air temperature, testing vehicle, load, pressure, speed, and many more.
