The European Tyre label is a new label system for all new tyres sold in the marketplace today. This system was introduced in November 2012 to provide customers more information on a tyres safety, environmental impact and fuel efficiency.
The label is split into three parts
The top left rates the tyres fuel efficiency from G (the least efficient) to A (the most efficient) – this may affect the fuel consumption by up to 7.5%
The top right rates the tyres wet grip This is similar to the above and rates the tyres wet braking distance from G (longest braking distance) to A (shortest braking distance) – this has as much impact as a 30% shorter braking distance.
The bottom rates the tyre rolling noise The bottom part of the label indicates the noise of the tyre with one black wave being the quietest and three loudest.
