PRO902001 Pro-Line Knuckles 2.0 M2 compound tire with foam. One of the most difficult classes in the sport of R/C--1:8th gas buggies. Drivers and equipment alike have to endure grueling one hour A-main in order to contend for the national title. The Knuckles 2.0 was bred to ensure longevity while giving your 1:8 car more agility while increasing traction. How is this achieved?
 The lugs are derived from the original Knuckles tire while increased lug spacing create greater traction enabling the tread to dig further into the surface below. The overall diameter has been reduced to allow for quicker responses while reducing the overall center of gravity of your 1:8 car. In turn, lap times are much more consistent while maintaining long-wear characteristics.
 Pack of 2. No breather holes.
