A:

An example tyre label is displayed on the right, and some of the labels may look familiar.

Fuel efficiency

The fuel efficency rating is calculated based on the tyre's rolling resistance to the road.

Wet grip

This rating shows tyres that perform well in the wet, and have a reduced stopping distance.

Noise levels

Rated in decibels, with a corresponding scale of 3 sound levels. A single sound wave is the best rating.
