The Dunlop Grandtrek AT20 gives control and comfort for high performance SUVs.
The Grandtrek AT20 is an all-terrain tyre that provides exceptional performance both on and off road. A unique silica compound and asymmetric tread design ensures low road noise, with a much lower fuel consumption, therefore higher mileage. Performance and comfort for luxury SUV: Aggressive all-season grip, good performance on wet and enhanced comfort.
Ultimate performance on gravel, mud and asphalt terrains
Low noise and superior wet grip
Excellent distribution of contact pressure
Particular tread design to maximise water dispersion
High aquaplaning resistance
Longer tread life
Increased contact with the road ensures more control of steering
High aquaplaning resistance
Enhanced comfort. The technology behind our tread compound means a smoother and more comfortable drive, with reduced noise in the cabin.
Aggressive all season grip. The all season tread design of the Grandtrek AT20 gives good grip and control in all weather conditions. Tyre to road contact is maximized for consistent traction and even tread wear.
Good performance on wet. Special tread grooves pump water away from the footprint, reducing the risk of aquaplaning in adverse conditions.
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.

29.11.2014fromjohn These were the tires that came from the factory. I got 60,000 miles out of first pair before I had to repalce
16.06.2013fromBill All on road driving, if i had keep them at 29psi as in the Toyota hand book they would not have lasted 30000 kms and they need to be rotated including the spare to get the kms
11.10.2011fromBaz Excellent tire. Our average heat in the summer is 50+ degrees centigrade in Dubai, no problems. Mainly highway driving, with quite a few trips to the desert in between. Even wear, slightly louder as they get older, traction in soft sand is very good. An excellent balance between comfort and light off road ability, shocking that they lasted this long.
