LUBRICANTS
The proper amount and type of lubricant is key to
successful mounting of radial off-road tires.
For lubrication, use only water-based or vegeta-
ble-based lubricant. Lubricants should be of a
type that vaporize over time and not leave any
residue on the rim or tire surfaces.
1. Paste lubricants should be diluted with water as
per specific lubricant manufacturers recom-
mendations.
2. Only lubricate all parts on the rim that are in con-
tact with the bead sole area of the tire.
FIGURE 2-8.
NOTE: Be careful not to apply lubricant in the O-ring
gutter.
3. When lubricating the tire bead, lubricant should
be sparingly applied to the tire bead surface
ONLY
. The lubricant should be painted or
sprayed on uniformly without any lumps in the
paste or soap. The total amount of lubricant
applied per tire should not exceed 50 grams
(1.75 oz.).
TIRE INSTALLATION
The preferred method for mounting tires is horizon-
tally and off of the truck, especially for initial tire
mounting on a new truck. For horizontal tire mount-
ing, a workman’s stand is recommended for working
inside the tire. Similar methods and precautions
should be used when mounting tires vertically, on the
truck.
NOTE: With each tire mounting, it is required that a
new O-ring and a new air valve be installed.
1. Before mounting tire to rim, remove all dirt and
rust from rim parts, particularly the O-ring
groove and bead seats. It is advisable to touch
up all metal parts with a good anti-rust paint to
prevent bare metal from being exposed to the
weather.
NOTE: Do not allow paint, rust or other
contamination to cover mating faces of lockring (6)
and rim (3).
Check to be sure that proper rim parts are used
for reassembly. Use of incompatible parts may
not properly secure the assembly resulting in
violently flying parts upon inflation.
