The Dunlop Grandtrek AT1 is an all-terrain tyre developed specifically for jeeps, minivans, and light trucks, most notably as the original equipment fitment on the iconic Toyota 70 Series LandCruiser — one of the most demanding applications a tyre manufacturer can earn. Designed for drivers who regularly cross between sealed roads and unsealed terrain, it delivers a smooth, comfortable on-road ride without sacrificing the confidence needed for genuine off-road conditions.
An asymmetric tread pattern with unique tread grooves provides strong grip on dry surfaces while operating at a reduced noise level, and longitudinal grooves drain water swiftly to increase hydroplaning resistance. Tough tectonic construction provides rugged strength that minimises cuts and punctures off-road, while high centre tread blocks excel in wet conditions, providing superior traction and reducing aquaplaning risk. The optimum tread pattern is designed for long mileage and reduced fuel consumption, making it a practical long-term investment for drivers who cover serious mileage across varied surfaces. The Grandtrek AT1 is a proven, OE-endorsed all-terrain tyre that earns its place on both gravel tracks and sealed highway in equal measure.
Best for:
Not intended for: Serious mud terrain, extreme rock crawling, or dedicated off-road use
Original equipment fitment on Toyota 70 Series LandCruiser: Engineered and validated to meet the demanding performance, load, and durability standards of one of the world's most capable and widely used 4WD platforms. Confidence that the tyre has been independently proven to the exact requirements of the vehicle it was designed for.
Asymmetric tread pattern with noise-reducing groove design: Unique tread grooves are shaped to provide strong dry grip and directional stability while disrupting the noise frequencies that cause road drone at highway speeds. A quieter, more refined on-road experience than the tyre's all-terrain classification might suggest.
Longitudinal water drainage grooves: Deep grooves running the full circumference of the tyre drain water rapidly from the contact patch in wet conditions. Strong aquaplaning resistance and reliable wet-road traction on rain-soaked highways and unsealed tracks alike.
Tough tectonic construction: A reinforced casing architecture provides structural resistance to the cuts, punctures, and impacts encountered during off-road driving on gravel, rock, and rough terrain. Confidence driving into remote or rough conditions without the risk of sidewall damage ending the journey.
High centre tread blocks: Elevated tread blocks in the centre of the tread maintain firm road contact in wet and muddy conditions, enhancing grip and braking stability. Reliable traction when roads are wet or tracks become soft, without the tyre losing confidence as surface conditions deteriorate.
Long-wear optimised tread compound with fuel efficiency focus: The tread compound is formulated to resist premature wear while also reducing rolling resistance across the tyre's service life. Lower fuel consumption and fewer tyre replacements over time, reducing the total cost of running an all-terrain fitment across high mileage.
