Dunlop Grandtrek ST 30 Review — Highway-Priority SUV for Urban NZ Drivers
Overall Rating: 8.6 / 10
Category: Highway Terrain SUV
Price in NZ: From $326 per tyre
Best for: Toyota Prado, Land Cruiser, Mitsubishi Pajero — highway-focused large SUVs
Quick Verdict
The Dunlop Grandtrek ST 30 is the highway terrain option in the Grandtrek family — prioritising tarmac refinement, fuel efficiency, and tread life over the off-road capability of the AT20/AT30/AT5 range. For Toyota Prado and Land Cruiser owners who use their large 4×4 primarily as a premium highway vehicle and only occasionally venture off sealed roads — the ST 30 delivers better highway comfort, lower road noise, and longer tyre life than an all-terrain alternative, at a competitive $326.

Performance Profile
Highway refinement: The ST 30’s strength. Quieter than the AT30 and significantly quieter than the AT5 — providing the motorway refinement that Prado and Land Cruiser owners expect from their premium vehicle.
Wet safety: Solid for a highway terrain tyre. The highway-focused compound maintains adequate wet traction for normal NZ road driving.
Tread life: Excellent — highway terrain tyres wear significantly slower than all-terrain alternatives. For high-mileage Prado owners, the ST 30’s tread life advantage over the AT range is substantial.
Light off-road: The ST 30 handles firm gravel driveways and farm entrances adequately — but for genuine off-road use, the AT30 or AT5 is the appropriate Grandtrek.
NZ Road Conditions Assessment
Auckland — Large SUV Owners: Very good. Prado and Landcruiser owners in Auckland who primarily drive on Auckland motorways and suburban roads benefit from the ST 30’s refinement and tread life. The AT30 is more appropriate if they regularly venture onto South Island gravel or Northland clay tracks.
Rural NZ: Not recommended for regular unsealed road use — the highway-terrain construction is not designed for significant off-road stress.
