Maxxis Shorty DH MTB Tyre 27. x 2.4 - 60 x 2 TPI - Super Tacky - Wire BeadMaxxis Shorty DH MTB Tyre 27. x 2. 4 60 x 2 TPI Super Tacky Wire Bead 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.
