Our pros needed a mid-spike tire that could handle dry, loose, blown-out corners as well as a bit of mud. The Shorty is that tire. A high-volume, dual-ply downhill casing makes the Shorty a more versatile option than a dedicated mud spike like our Wet Scream. Large, tall and slightly staggered side knobs penetrate loose soil to provide predictable, stable cornering at warp speeds. Large Aggressive Lugs 3C Maxx Grip Dual -Ply Casing With Butyl Insert An extra piece of butyl rubber that extends from the bead of a downhill tire up into the sidewall. The butyl insert helps prevent pinch flats, protects the rim from hard hits and adds sidewall stability The most important part of a tire is arguably the rubber compound within the tread. By changing the amounts of various components of the rubber formula, engineers can make two identical looking tires perform completely differently. This tyre uses 3C MAXX GRIP. 3C Maxx Grip uses the softest rubber compounds to offer the ultimate in grip and slow rebound properties for unparalleled traction in downhill applications. The function of the bead is to keep the tire in contact with the rim while the tire is inflated. A wire bead is a rigid metal wire is utilized as bead material in applications where ultimate strength is needed and transportability is not a factor.
