New from HPI Racing are these ATTK tires in S compound. The sticky S compound rubber is softer than the stock D compound tires, giving them more grip for faster lap times. The tread is a mid-sized block design for high grip in a wide variety of off-road conditions. These tires are designed to fit on BLITZ truck wheels with step-down (3.0/2.2) asymmetrical construction. Sold in pairs, inner foams included.
