For mounting tubeless tires, the  procedure is about the same as for tube
type tires except that it is not necessary  to inflate twice. Cleaning the rim is
again critical because the tire depends  on the rim for its air seal. Make sure the  inside of the tire is clean and dry. If tires  have been stored outdoors, any water in the tire must be removed and the tire  dried before mounting. Water vapor in  the inflation air tends to cause rim  corrosion. The valve stem must be  inspected to make sure it is tight in the rim and that the rubber grommet
between the rim and stem is in good  condition. To install the tubeless tire on the rim, lubricate both bead seats of the rim and  both tire beads to ensure damage-free  and uniform mounting. Bead lubricant  must also be used during demounting to  avoid damage to the bead area. Due to  their greater sidewall flexibility, it may be necessary to use an inflation aid to help seat radial tubeless tire beads. For detailed mounting and demounting
instructions, refer to the wall charts  available through OSHA Occupational
Safeaty and Health Administration (www.osha.gov). When using tire irons,
exercise caution to prevent damage to  the tire or rim. Check that the distance between  the tire GG ring and the top of the rim or wheel flange is uniform all around the tire, and that the distance  is the same on both sides of the tire. If this distance is not uniform, the bead is not properly seated.
If the GG ring in no concentric with  the rim flange, it is recommended that
the “inflate-twice” procedure also be used in mounting tubeless tires in order
to seat beads properly.
