Tyre buying guide
The tyre labelling provides clear, concise, accurate information on tyre performances over 3 specifications;
- Wet Grip
- External Rolling Noise
The Fuel-Efficiency label provides you with information on how well tyres perform with rolling resistance. Rolling resistance, also known as ‘rolling friction’ and ‘rolling drag’, is the resistance between the tyre and the road surface, and can be affected by the material the tyre is made from. Fuel-efficiency is graded from A (most efficient) to G (least efficient). For example, switching from grade G tyres to grade A tyres can reduce fuel consumption by up to 20%.
The Wet Grip label provides you with information on how well the tyre will grip on wet roads. Tyres with excellent grip in the wet have shorter breaking distances on wet roads.Tyres are graded from A (most grip) to G (least grip).
A car fitted with an A-rated tyre will stop up to 4 car lengths shorter from a G-rated tyre. This is an important factor if you drive in a wet climate.
The External rolling noise label provides you with information on how much noise a tyre will produce outside of the car.
Tyre's exterior noise grading is expressed in decibels. Below 70dB considered quiet, future EU regulation will require noise level to be below 73dB.
The Noise label is displayed as wave pictogram
- black waves = 68dB or below. Noise level below future limits
- black waves = 69dB to 72dB. Noise level equal to or below future limits
- black waves = 73dB and above. Level greater than the future limit but complies with today’s noise regulation
