Can you explain tyre labelling scores?
There are 3 main categories that are scored. Each one is as follows:
• Rolling Resistance
The grades range from A to G, informing you about the relative fuel efficiency performance level. A is the highest performance tyre in its category; G is currently the least performing.
• Wet Grip
The grades range from A to G, informing you about the relative wet grip performance level. A is the highest performance tyre in its category; F is currently used to represent the least performing.
• External Noise
The tyre's exterior noise is expressed in decibels (dB) and will show one, two or three sounds waves. These sounds waves highlight the performance of the test against the current law. Three bars indicate that the tyre meets current limits, two bars indicates that the tyre meets limits that are to come into effect in the future and one bar shows that the tyre is a further 3dB below future limits.
