TUBELESS TIRE MOUNTING

american business — Tue, 07 Jul 2009 22:54:20 +0000

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.

Insert the tube into the tire and partially inflate it to round out the tube. Apply rubber lubricant to the inside and outside surfaces of both beads and to the portion of the tube that appears between the beads. Do not allow lubricant to run down into the tire. Apply the lubricant with a cloth, swab, or brush. For detailed, illustrated instructions on procedures and proper use of tire tools in mounting and demounting Goodyear radial truck tires on various types of rims, see the wall charts available through RMA After mounting and before inflating the tire, inspect all components of
multipiece rims to make sure they are in place.

See that tires are properly mounted and seated on the rims by checking the distance between the tire GG ring and the rim flange. This distance should be the same all the way around the tire; that is, the rim flange must be concentric with the GG ring (refer to the photograph Figure 3.4 below, and Figure 3.3 on page 19, for GG ring location on tire) and the distance must be the same for both sides.
