Toyota Motor Corporation has selected Sumitomo Rubber Industries Ltd’s DUNLOP GRANDTREK H/T31 tyre as original equipment (OE) in Japan for its recently launched LEXUS GX550 SUV.

In addition to the dependability and durability that the GRANDTREK series has established, the GRANDTREK H/T31 aims for on-road performance. The product uses new tread rubber and a H/T (Highway Terrain) pattern to provide a high level of anti-wear performance, good fuel efficiency and quiet operation. In order to increase visibility and create a more opulent overall design appeal, the tyres also employ the Nano Black design method, which colours brand insignia on tyre sidewalls a darker shade of black.

With its powerful but economical engine and sturdy construction, the new GX550 offers exceptional driving performance. With its unique design, cutting-edge suspension and driving support system, and 18-inch tyres, the OVERTRAIL+ delivers both off-road and on-road performance. Toyota SUVs have long been equipped with DUNLOP's GRANDTREK line of tyres as standard equipment.
