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.
Features and Benefits
Asymmetrical Tread Design: The outboard tread design provides enhanced stability in turns, while the inboard design provides increased performance for all seasons.
Offset Center Rib: The rib enhances high speed stability and improves steering response catering to the needs of today's drivers.
Ventless Technology: The molds used to manufacture the Zeon XSTA incorporate special venting technology in the tread area to provide a crisp, clean, premium appearance.
Circumferential and Transverse Grooves: Expels water in all four directions to increase water evacuation, resist hydroplaning and enhance wet traction.
