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, derived from the original Knuckles tire with increased lug spacing, create greater traction, thus 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.
