When added to the inside of the tire the beads will automatically distribute themselves to counter act the heavy spots when the motorcycle is in motion.  This results in a very smooth ride as well as prolonged tire life.There are many ways to install the beads.  The easiest method is to just pour them in during mounting.  Alternatively, follow the photos above to cut the two bags.  Apply the 2 oz bag to the front tire using the applicator tube, similarly apply the 2 oz tube to the back tire.  Screw out the valve core using the tool provided before pouring in the beads.  To help the beads go down smoothly you can gently tap the stem during the process.  Some folks even use an air compressor to blow the beads in.Please note, you can't use these with a liquid sealer, as they will not be able travel freely inside the tire.Tire Chart: Front Tire:   80 - 120 mm tire width   ---   1 oz   130 mm tire width          ---   2 oz Rear Tire:     130 mm - 240 mm width   ---  2 oz      250 mm - 360mm tire width   --- 3 oz   195 - 205 car tires on the rear   ---  3 oz Dual Purpose / Off Road with Rim Locks:   Front - 80 - 120 mm tire width   --- 2 oz   Rear - 130 -230 mm width   --- 3 oz   For Rim Locks - add one ounce to suggested amount for that tire size.
