Fuel Efficiency/Rolling Resistance
As a tyre rolls, it deforms and dissipates energy. This lost energy is known as rolling resistance and directly impact on fuel consumption. Graded A (best) to G (worst), the difference between the two is a 7.5% loss of fuel economy.
Wet Grip/Braking Performance
Tyres with excellent wet grip have shorter braking distances on slippery roads, essential for keeping you safe in the rain. Graded A (best) to G (worst), the difference in braking between the two is 18 metres or four car lengths.
Exterior Noise Emission
A tyres exterior noise grading is expressed in decibels (dB) and accompanied by one, two or three sound waves. Graded 1 (best) to 3 (worst), the best are designed to exceed future EU noise regulations.
