The Dunlop Grandtrek AT3 provides superb off-road and on-road performance for 4x4s and SUVs.
The Grandtrek AT3 is an all-terrain 4x4/SUV tyre that achieves the optimum balance of on and off-road performance. A combination of unique silica compound and distinctive tread pattern ensures low road noise, high aquaplaning performance and universal traction in a variety of conditions. Outstanding all-terrain performance: High traction on and off the road and low noise. Ideal for heavy duty 4x4 vehicles.
Technology (Features):
The Specific Bead Seat System enhances control and conveys outstanding road feedback.
A Hybrid Overlay Technology that reduces circumferential deformations at high speeds.
Jointless Belt (JLB). A Hybrid Overlay Technology that reduces circumferential deformations at high speeds. Benefits: Superior high speed stability
Consumer benefits:
High traction on and off the road
Low noise
Ideal for heavy duty 4x4 vehicles
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.
Longer Lasting. The tyre’s flatter tread profile ensures that pressure is evenly spread across the contact patch, which ensures even wear and longer tyre life.
Low noise. 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. Like the grip between your hand and the steering wheel, the Specific Bead Seat System enhances control and conveys outstanding road feedback. Benefits Enhanced road feedback; greater stability and precision.
The Tire Labeling Ordinance specifies the information requirements on fuel efficiency, wet grip and external rolling noise from tires. In addition, reference is made to the winter properties of the product.
The EU 1222/2009 regulation that has been in force since November 1st, 2012 has been revised and will be replaced by regulation EU 2020/740 from May 1st, 2021; From this point on, new requirements apply. The rating classes for fuel efficiency, wet grip and exterior noise have been changed and the layout of the EU label has been adjusted. The manufacturer's product data sheets stored in the EU database can be downloaded via a QR code integrated into the label. Information on snow grip and ice grip is also newly included for tires that meet these criteria.
The following tires are exempt from the regulation: - tires that are designed exclusively for installation on vehicles that were first registered before October 1, 1990 - retreaded tires (until a corresponding extension of EU VO 2020/740 has taken place) - professional off - Road tires - Racing tires - Tires with additional devices to improve traction, eg studded tires - T-type emergency tires - Tires with a permissible speed below 80 km/h - Tires for rims with a nominal diameter ≤ 254 mm or ≥ 635 mm
The criteria and evaluation classes at a glance
fuel efficiency
The fuel consumption depends on the rolling resistance of the tyres, the vehicle itself, the driving conditions and the driving style of the driver. The measured rolling resistance (rolling resistance coefficient) of the tire is divided into classes A (highest efficiency) to E (lowest efficiency).
If a vehicle is completely equipped with class A tires, a consumption reduction of up to 7.5%* is possible compared to class E tyres. In the case of commercial vehicles, it can even be higher. (Source: European Commission Impact Assessment * when measured according to the test methods set out in Regulation (EU) 2020/740)
Please note: Fuel consumption depends to a large extent on your own driving style and can be significantly reduced by driving in an environmentally friendly manner. Tire pressure should be checked regularly to improve fuel efficiency.
wet grip
Wet grip is divided into classes A (shortest braking distance) - E (longest braking distance).
If a car is equipped with class A tires, compared to class E tires, a braking distance of up to 18 m can be reduced when braking from 80 km/h (on a road surface with average grip).* *Source: wdk Economic Association of the German Rubber Industry eV
Please note: Traffic safety depends to a large extent on your own driving style. The stopping distances must always be observed. Tire pressure should be checked regularly to improve wet grip.
External rolling noise
The noise emitted by a tire affects the overall volume of the vehicle and affects not only your own driving comfort, but also the noise pollution of the environment. In the EU tire label, the external rolling noise is divided into 3 classes from A (lowest rolling noise) - C (highest rolling noise), measured in decibels (dB) and compared with the European noise emission limit values for external tire rolling noise.
A The pictogram with the classification "A" indicates that the tire's external rolling noise is more than 3 dB below the EU limit value in force until 2016. B The "B" classification means that the tyre's external rolling noise is up to 3 dB below or equal to the EU limit value in force until 2016. C The classification "C" indicates that the specified limit value is exceeded.
