FAQ
Is the Dunlop Grandtrek AT5 good?
Yes, for drivers who use their vehicle on both paved roads and rough terrain. According to Dunlop Thailand, the AT5 lasts 50% longer, handles 25% better, grips 10% better in the wet and is 10% more comfortable than the previous model.
Is the Grandtrek AT5 durable and long lasting?
Yes. Dunlop uses the Super Abrasion Carbon compound to slow wear, and Sumitomo Rubber strengthened the shoulders and reshaped the tread profile for even pressure so it lasts longer than the AT3, plus cut-resistant side blocks and a Stone Ejector that pushes out stones.
How capable is the Grandtrek AT5 off-road?
It handles dirt, rocks, gravel and unpaved roads. Dunlop designed the AT5 for both everyday driving and rough trails. If you regularly drive deep mud or heavy rock, a Rugged Terrain (R/T) or Mud Terrain (M/T) tire is a better fit.
What vehicles is the Grandtrek AT5 for?
Pickups, raised 2WD and 4WD pickups, PPVs and SUVs on 15–20 inch rims. See the sizes Subphaisal has ready to ship in the size table above, and choose the size that matches your vehicle's original tires.
Where is Dunlop from and where is it made?
Dunlop is a tire brand from England. Today, Dunlop car tires in Thailand belong to Japan's Sumitomo Rubber Group. DUNLOP was the name of the early pneumatic tire in 1888, and Dunlop of England set up Japan's first modern rubber factory in 1909, which later became Sumitomo Rubber. Dunlop Thailand says its main production base is the Sumitomo Rubber (Thailand) plant in Rayong, but does not state the plant for the Grandtrek AT5 specifically.
What warranty does the Grandtrek AT5 have?
Every tire bought from Subphaisal is covered by the manufacturer against manufacturing defects for 2 years or 50,000 km, for both store pickup and delivery, plus road hazard cover for cuts, bulges and punctures for 120 days or 7,000 km when you buy 4 tires, install them at a branch and register per the brand's terms. See the warranty page for details.
