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.
Shorter braking distances.
Good grip and cornering stability.
Very good water draining ability, protecting against risks of aquaplaning.
The solid shoulder blocks with channels to the tread provide steering precision and cornering stability.
The wide, circumferential grooves gulp and expel water.
The increasingly-deep lateral grooves reduce road noise.
The ventilated grooves reduce the "suction" effect and hence noise inside and outside the vehicle.
