The J1 Tool is a slightly altered and condensed version of the original Bead Saver System. The J1 is a 2-piece system that mounts and dismounts all standard 19.5 inch, 22.5 inch and 24.5 inch tubeless tires up to a 315/80R22.5, including those mounted on aluminum wheels. It differs from the original system in that each process is done completely while the tire is flat on the ground. It is no longer necessary to stand the tire up in order to dismount the second bead! J1 Tool Includes: The J-1 bar, and 1 Wide Clevis #12902-W. HOW THE J1 Tool WORKS: - The first bead is dismounted with the clevis & crook/spoon end. - The second bead is dismounted with the J-1 end without picking the tire up. - The first bead can be mounted with the J end. - Two Beadkeepers can be used to assist with mounting.
