The Dunlop Grandtrek AT22 is a highway terrain all-season tyre designed for large 4x4s and SUVs, most notably specified as original equipment for the Toyota LandCruiser, where meeting the demanding standards of a leading 4WD manufacturer for handling, ride quality, and minimal noise was a core engineering requirement. Built for drivers who split their time between long highway runs and occasional off-road excursions, it delivers refined on-road composure without sacrificing the capability to handle dirt tracks, gravel, and moderate off-road terrain with confidence.
A silica tread compound delivers superior braking, cornering, and handling in all conditions while also reducing rolling resistance to improve fuel economy, and a flat ribbed footprint maintains continuous road contact throughout the drive, improving steering responsiveness and driving stability with shoulder ribs providing additional biting edges for cornering and braking. Robust casing construction offers extra protection against the hazards commonly encountered in severe off-road conditions, significantly reducing the risk of sidewall damage. The Grandtrek AT22 is a proven, manufacturer-endorsed tyre that delivers the refinement of a highway tyre with the structural confidence to go further off the beaten track when required.
Best for:
Not intended for: Serious mud terrain, rock crawling, or dedicated off-road use
Silica tread compound: Enhances braking, cornering, and handling across wet and dry road surfaces while simultaneously reducing rolling resistance. Confident all-condition traction and improved fuel economy across the high annual mileage that large SUV drivers typically cover.
Flat ribbed footprint with continuous road contact: The optimised tread profile maintains a consistent, even contact patch with the road surface throughout the drive. Precise, responsive steering and stable, predictable handling on highways and urban roads at any load.
Shoulder ribs with additional biting edges: Reinforced outer shoulder blocks generate extra grip under cornering and braking forces on both sealed and unsealed surfaces. Shorter braking distances and more confident cornering for a large, heavy 4x4 where stability margins matter most.
Robust reinforced casing construction: Extra structural reinforcement in the tyre casing protects against cuts, impacts, and sidewall damage commonly encountered on rough or unsealed surfaces. Greater confidence when venturing off sealed roads without the risk of a puncture or sidewall failure ending the trip.
Original equipment fitment on Toyota LandCruiser: Engineered and validated to meet the strict performance, noise, and durability standards set by Toyota for one of the world's most demanding 4WD platforms. A tyre that has been independently proven to the standards of a leading 4WD manufacturer, not just general road use.
All-season tread compound and design: Compound and tread geometry are developed to maintain grip and stability across wet, dry, and light winter conditions year-round. Year-round usability from a single fitment without the trade-offs in comfort and noise that come with more aggressively patterned all-terrain tyres.
