Overview: In some conditions in off-road racing, there is no denying that a slick tire is the fastest way around the track. Indoor and occasionally outdoor clay surfaces become so tacky or free of dust and debris that a total slick tire is an advantage. For years drivers have sanded, ground and hand sculpted tires in search of that elusive slick carcass, now, JConcepts has the Smoothie 2. Available as pre-mounted, the Smoothie 2 is glued to the genuine 3353Y JConcepts wheel. Released as a 2.2” bead mounting diameter, the JConcepts Smoothie 2 mount straight to the latest generation wheels for that all important reactive feel. The carefully profiled slightly thickened tire carcass rolls through the turns with efficiency while the maximum smooth surface area grips the specialty surfaces like no other. The Smoothies include Dirt-Tech inserts which have made an immediate presence on the racing scene since their release. The identifiable gray color with custom sculpted features, are blended into the insert material which provide racers a durable option capable of being used in medium to extremely high-traction conditions. Features: JConcepts design and function Pre-mounted for convenience Thickened, Smoothie 2 concept 2.2” bead mounting size for compatibility Carefully shaped carcass = rolling speed Includes 2.2" Dirt-Tech (gray) inserts Mounted on 3353Y JConcepts wheels
