The Roadstone Roadian HT features four straight grooves which evacuate water from tread for wet traction and protection against aquaplaning. The tires are capable of supporting off-roading on rough terrain such as dirt, gravel and grass with their optimized kerfs and twin blocks which balance varying functionality. The concaved shoulder blocks easily handle the stress of cutting sharp corners and promote greater handling control. The interior is reinforced with two steel belts covered with polyester for added strength and resistance to deformation.
