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.
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
High traction on and off the road
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.
EU Tyre Label and Efficiency Classes
The European Union has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012.
Three different areas are tested: rolling resistance, wet grip and the rolling noise the tyre makes on the road.
The following are not affected by the EU Tyre Label: retreaded tyres, professional off-road tyres, racing tyres, tyres with additional devices to improve traction such as spiked tyres, T-type emergency tyres, special tyres for fitting to vehicles first registered before 1 October 1990, tyres with a maximum authorised speed of 80 km/h, tyres for rims with a nominal diameter of 254 mm or less or 635 mm or more.
With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decision-making aid.
Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safety-relevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc.
Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer. These tests usually focus on further safety-relevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer.

04.08.2010fromPhil Good tyre. Excellent in wet. Lasts much longer than previous model Grandtreks.
22.06.2010fromKiwi I do a lot of open road driving and towing a boat or trailer. No problem with grip or cornering.
