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
High traction on and off the road
The Grandtrek AT3 is an all terrain 4x4 tyre that comfortably handles on and off-road conditions. A straight centre rib helps to deliver good high speed handling and stability.
The tyre's flatter tread profile ensures that pressure is evenly spread across the contact patch, which ensures even wear and longer tyre life.
The tyre's 2 in 1 shoulder block pattern reduces tyre noise levels and helps to maintain on and off-road traction.
Specific Bead Seat System
Strengthens the link between tyre and rim for a more precise driving experience. The Specific Bead Seat System enhances control and conveys outstanding road feedback, greater stability and precision.
Jointless Belt (JLB)
A Hybrid Overlay Technology that reduces circumferential deformations at high speeds for superior high speed stability, smooth and even wear.
