1. Fuel Efficiency
Use this diagram to see how a tyre performs on fuel consumption. Fuel-efficiency is graded from A (most efficient) to G (least efficient). Save up to £110 or 80 litres of fuel over the life of the tyres. That's for a car fitted with four A-rated tyres driving at 50 mph - it uses 7.5% less fuel than with G-rated tyres. Results can vary with type of car or climatic conditions but the performance gaps are proven.
2. Wet Grip
This chart grades a tyre on how well it brakes in wet conditions. Performance scales from A (the safest, stopping in the shortest distances) down to G (least safe, with longest braking distances). Stop up to 4 car lengths shorter. For a car fitted with four A-rated tyres driving at 50 mph, stopping distance can be up to 18 metres or 30% shorter than with G-rated tyres.
3. Noise Levels
This diagram shows you a tyre's noise level in decibels (dB). The 3-wave pictogram tells you how it rates in relation to future European mandatory limits. Tyre noise heard outside the car doesn't necessarily relate to what you hear inside the car... Three black waves = High noise level, greater than the future limit but conforms to current EU rules. Two black waves = Average noise level, equal to or below future limit by up to 3 dB(A). One black wave = Low noise level, from 3 dB(A) below the future noise limit.
