Dunlop Grandtrek AT5 Review — Dunlop’s Most Capable AT for Serious NZ Off-Road
Overall Rating: 9.0 / 10
Category: All-Terrain — High Capability
Price in NZ: From $453 per tyre
Best for: Toyota Prado, Land Cruiser, Mitsubishi Pajero — serious off-road capability
Quick Verdict
The Dunlop Grandtrek AT5 is the most off-road-capable tyre in the Grandtrek family — positioned for drivers who genuinely venture beyond what the AT30 handles comfortably. While the AT30 prioritises tarmac refinement with decent off-road capability, the AT5 flips that priority: maximum off-road traction first, with adequate tarmac performance. For Toyota Land Cruiser, Prado, and Mitsubishi Pajero owners who take their vehicles into demanding NZ backcountry — river crossings, steep clay faces, rocky high-country tracks — the AT5 is the Grandtrek to choose.

Performance Profile
Off-road: The AT5’s defining strength. Deep, aggressive tread blocks with wider void ratios than the AT30 provide significantly more bite in mud, soft ground, and rocky terrain. The multi-ply reinforced sidewall resists punctures from sharp NZ schist and volcanic rock. Stone ejectors prevent the embedded-stone damage that plagues less robust AT designs on NZ’s metal roads.
On-road: Acceptable — louder than the AT30 and less comfortable at highway speeds. For Land Cruiser and Prado owners who primarily use their vehicles as daily drivers, the AT30 is a more comfortable choice. For genuine off-road enthusiasts who occasionally drive on tarmac, the AT5’s tarmac manners are acceptable.
Tread life: Good for an aggressive AT tyre — the deeper tread depth gives the AT5 longer life than it would otherwise achieve given its aggressive design.
NZ Road Conditions Assessment
Rural South Island: Outstanding — the AT5 handles the demanding terrain of Canterbury high country, Otago station roads, and Fiordland access tracks with confidence. The reinforced sidewalls protect against the sharp rock hazards common in South Island backcountry.
Rural North Island: Very good — handles Northland’s clay hills, Waikato’s muddy farm access, and Coromandel’s rough tracks. Less refined on tarmac than the AT30 for urban driving.
