Michelin's new line of DH tires for 2010 is officially launched. --- Michelin has brought back their Dh line for 2010 with a few new names, some slightly modified tread and different sidewalls. The Gripp'r, Rock'r and new mud tires are all slightly new version of the old Michelin standards (comp 16, Comp 24 and Mud 3). The comp 32 replacement isn't at the show, but will be a large sized 2.6 instead of a 2.8. The sidewalls have been modified slightly with an external reinforcement, especially on the UST tires, that will help prevent pinch flats. The compound has slightly slower rebound than before. The Rockr is a comp 24 with a few more sipes to open it up, and pre removed mid knobs, which was a popular modification. The Rock'r is a comp 16 with much stiffer sideknobs in 2,5", which is what many had asked for.
