Don't need to as the muchroom plug is highly compressed and the nozzle is pushed in the hole in the tire that has been roughed up with a special tool included. The plug is pushed out of the nozzle and expands. Then the tool is withdrawn leaving the plug in place. Trim the stem of the plug to the suface length of the tire tread and allow a few minutes for the tire cement to set and your done.ZetaTre said:Very interesting tool...But how do you get to the inside of the tire? Do you have to remove it from the rim (that's quite hard on tubeless)?
