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
Excellent performance on dirt and gravel
The Grandtrek AT2 is a 4x4 tyre that meets the challenge of driving on tough terrain. Its all terrain tread design helps to deliver reliable handling on gravel and dirt roads.
The tread blocks are arranged to reduce noise emissions and provide a smoother, quieter drive.
Good wet traction
The tread features wide grooves that provide good traction on wet roads and more efficient drainage in extreme weather.
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.
Maximum Flange Shield (MFS)
A rim flange protection system. MFS employs a profile of rubber that runs around the circumference of the tyre above the wheel flange. This creates a protective buffer zone to protect expensive alloy wheels from kerbing.
Jointless Belt (JLB)
A Hybrid Overlay Technology that reduces circumferential deformations at high speeds for superior high speed stability, smooth and even wear.
