Designed for maximum street abuse, with a thick rubber and high thread count casing that allows up to 110 psi. Shadow's most technical tread pattern to date, we used special sipes on the outer edge to hold fast on wallrides and vertical surfaces. The side tread is positioned out of the way for smooth grinds with no hang ups. The smooth center keeps rolling resistance to a minimum. The ultimate street and park tire. Weight: 31.6ozs.
