Thunderer OA421 Tires

Commercial Truck - Drive

Thunderer OA421 is a premium regional and mixed service radial tire made for on and off-road applications. It was specially engineered to run cool and provide abrasion and cut resistance, thanks to its high durability and casing integrity. With the special tread block pattern, Thunderer OA421 tire offers excellent traction and keeps the stones away from getting stuck in between the tread for better control and performance. The closed continuous shoulder rib on inner and outer side of the tire helps to fight irregular wear and distribute an even pressure throughout the whole surface of the tire.
