The EU is introducing mandatory tyre labels that provide information on fuel efficiency, wet grip, and noise levels. The fuel efficiency label uses a scale from A to G, and the difference in fuel consumption between the best and worst tyres can be up to 7.5% for cars. Wet grip is also rated A to G based on braking distances, with a 30% difference between the best and worst tyres. The noise label indicates whether a tyre meets the current or future EU noise limits. The labels aim to reduce fuel costs and environmental impact while maintaining safety.

1. Tyre labelling
Fuel consumption, wet grip and noise pollution
Tyres and fuel consumption
Overall, tyres are responsible for around 20% of vehicle fuel consumption and can
affect fuel costs in two ways:
Tyre pressure – reduced tyre pressure increases rolling resistance and hence fuel
consumption so you should check pressures regularly.
Materials and construction – tyre manufacturers can choose materials and
manufacturing techniques to reduce rolling resistance at the recommended pressure.

2. On the label
Fuel efficiency (rolling resistance)
Using the same design as that used for the familiar energy labelling on fridges,
freezers etc. the label will show the tyre's fuel efficiency on a sliding scale from A
(best) to G (worst).
The difference between the best and worst fuel consumption can be as much as
7.5% for cars.

3. As well as introducing labelling requirements, EU regulations will introduce
mandatory reductions in maximum permitted rolling resistance in two stages -
November 2012 and November 2016.
Wet grip
Reducing rolling resistance too far can adversely affect stopping distance on wet
roads. To make sure that safety standards are maintained at the same time as
achieving environmental improvements through reduced fuel consumption, the EU is
also introducing minimum levels of wet grip performance.
The new label will show wet grip performance measured under strictly controlled
conditions and rated from A (best) to G (worst).
The difference in stopping distance between each grade will be one or two car
lengths when braking from 50mph. Overall the difference in braking distance
between best and worst (A to G) will be around 30%.

4. Noise
As well as their contribution to fuel consumption, tyres affect the environment
because of the exterior noise they generate.
To reduce noise pollution from road transport, tyre manufacturers must comply with
regulations setting increasingly stringent maximum limits for the noise that tyres
generate external to the car.
The bottom part of the label shows exterior noise level, measured in decibels (dB).
 A single 'sound wave' shows that the tyre's noise level is 3dB
better than the future European limit.
 Two black 'sound waves' shows that the tyre meets the future
European limit.
 Three black 'sound waves' shows that the tyre only meets the
current European limit for noise.
