Homologated tyres are those that have been approved directly via a manufacturer. These tyres are ones that have met the standards and regulatory requirements of the manufacturer.
The energy lost when a tyre is in motion is known as 'rolling resistance'. This has a direct impact on fuel consumption.
A tyre's rolling resistance score ranges from A to G. Over the life of the tyre, fitting an A rated tyre could save you up to 6 litres of fuel when compared to a G rated tyre.
A tyre's wet grip capacity is expressed in Grades from A to G.
The difference in braking distances between each grade is roughly 3m - an average car length. This makes average stopping distance between an A and G rated tyre 18m. That's 4 car lengths.
The exterior noise grade of a tyre is expressed in decibels - accompanied by one, two or three sound waves, with one wave being the best noise level performance.
To achieve the best grade, a tyre’s noise level must be at least 3dB under the legal limit set by the EU.
Your safety & driving pleasure under control
Excellent safety on wet roads.
- In deep water... a directional tread pattern with wide circumferential grooves maximises water dispersal to reduce the risk of aquaplaning.
- On normal wet roads, the g-Grip features a "vortex" tread pattern, designed to disperse water more quickly for better braking and handling.
Unrivalled driving pleasure on dry roads.
- On straights and in bends... substantial shoulder tread blocks and a continuous central rib give a rapid steering response and superb control. With improved braking, its "chamfered edge" sipes improve the stability of each tread block better braking on dry roads.
