Fuel efficiency is important to reduce both CO2 emissions and the cost of driving. Each tyre can be categorised for its fuel efficiency.

Tyres are rated between A – E; A being the most fuel efficient, E bring the least fuel efficient.

The difference between each category means a reduction or increase in fuel consumption of 3-4%.

Wet grip is a critical safety feature, relating to how quickly a tyre can stop on wet roads.

Tyres are rated A – E; A being the shortest braking distances in the wet, E being the longest braking distance in the wet.

The difference in each category can mean an extra one to two car lengths (3-6 metres) on the stopping distance.

This relates to the external noise made by the tyre and is measured in dB (decibels). There are three ratings for noise: 'A', 'B' and 'C'. 'A' produces the least external noise levels, whilst 'C' produces the highest
