Dunlop Grandtrek AT25 Review — Premium All-Terrain for NZ Luxury SUVs

Overall Rating: 8.7 / 10

Category: All-Terrain — Premium Highway Focus

Price in NZ: From $448 per tyre

Best for: Toyota Land Cruiser Prado, Lexus GX, Mitsubishi Pajero — premium lifestyle SUVs requiring occasional off-road capability

Quick Verdict

The Dunlop Grandtrek AT25 fills the gap between the budget AT20 and the capable AT30 in Dunlop’s all-terrain lineup, but with a specific focus on premium highway SUVs rather than working utes. It is quieter and more refined than the AT30, with a compound specifically tuned for the higher loads and broader temperature range demanded by large, heavier premium SUVs. For Prado and Lexus GX owners who venture off-road occasionally but spend most of their time on sealed NZ roads, the AT25 delivers a more comfortable daily drive than the AT30 without sacrificing the all-terrain credentials these vehicles are purchased for.

Key Specifications

Performance Profile

On-Road Performance — The AT25’s Strength

The AT25’s compound is softer and more highway-oriented than the AT30, delivering:

• Lower road noise — significantly quieter on motorways than the AT30 or AT5
• Improved ride comfort — less transmission of rough road surfaces into the cabin
• Competitive wet traction for an AT tyre in its class

This highway refinement makes the AT25 particularly suited to the Prado and Lexus GX market — large, expensive SUVs where interior refinement matters as much as capability.

Off-Road Performance

Solid but conservative — the AT25 handles light to moderate off-road conditions confidently. Gravel roads, farm access tracks, and compacted dirt surfaces are handled well. For more demanding conditions (river crossings, deep mud, steep clay faces), the AT30 or AT5 is more capable.

NZ Context

Prado and Lexus GX owners in Auckland’s North Shore, Waikato lifestyle blocks, and coastal South Island find the AT25’s balance ideal — it handles the gravel driveways and unsealed access roads that come with property ownership without the noise and fuel economy penalty of a more aggressive AT tyre.

NZ Road Conditions Assessment

Auckland and lifestyle property areas: Excellent — the AT25’s combination of highway refinement and moderate off-road capability matches the usage pattern of most luxury SUV owners in greater Auckland, Waikato, and Bay of Plenty. These drivers spend 70-80% of their time on sealed roads but need genuine off-road confidence for property access and occasional backcountry trips.

South Island: Good — handles the mixed sealed/unsealed roads of lifestyle South Island areas well. For serious South Island backcountry use, the AT30 or AT5 provides more capability.

AT25 vs AT30 — Which Grandtrek?

The AT30 is actually cheaper ($388) and more off-road capable. Choose the AT25 specifically if highway quietness and premium ride comfort are top priorities for your Prado or Lexus GX.
