UK Tyre Law

Tyres are the only part of the vehicle which are in contact with the road. Safety in acceleration, braking, steering and cornering all depend on a relatively small area of road contact. It is therefore of paramount importance that tyres are well maintained and that their tyre tread depth is above the legal limit to maximise performance and safety.

By law, car tyres must have a minimum of 1.6mm of tread in a continuous band throughout the central three-quarters of the tread width and round the entire circumference of the tyre. The driver of the vehicle is responsible for making sure their tyres are legal and in a roadworthy condition.

The penalty for driving with an illegal tyre is a fine of up to £2,500 and three penalty points per tyre. This could cost your licence, or worse still a life.

EU Tyre Labelling

The Label

The label is similar to labels already being used for white goods such as fridges, freezers and washing machines. The EU Tyre label will inform you about 3 key performance criteria of the tyre:

  • Fuel efficiency
  • Wet grip
  • External rolling noise
(or rolling resistance) – Graded A to G.
A = Most efficient and G = Least efficient. (D not used)
(or braking performance on a wet road) – Graded A to G
A = shortest braking distance and G = longest braking distance. (D and G not used)
measured in decibels (dB) – Tyre categorised in 3 classes illustrated by
3 waves. 1 wave = quieter tyre to 3 waves = louder tyre
(when comparing identical section widths).

Fuel Efficiency / Rolling Resistance

A rolling tyre deforms and dissipates energy. The energy that’s lost is known as rolling resistance and directly impacts on fuel consumption and the environment.

With lower rolling resistance, the tyre uses less energy, less fuel and in turn, less CO2.

Wet Grip / Braking Performance

Tyres with excellent wet grip have shorter braking distances on slippery roads, essential for keeping you safe in the rain.

These ratings are measured from the distance travelled by a car after braking at 50mph in the wet.* 30% shorter braking distance between best and worst class for a full set of tyres fitted to an average car.

Did You Know?

The difference between A and G is 18 metres, That’s four car lengths or eight Smart cars.

Noise Emission / Exterior Noise

A tyre’s exterior noise grading is expressed in decibels (dB) and accompanied by one, two or three sound waves on the label.

One wave is the best performance, three is the worst. ln fact, three bars is the current limit, while two meets future laws and one is a further 3dBs below.
