Mounting
1. Before mounting tire on a used rim, be sure
flange area (particularly the bead seat area) is clean and
smooth. Remove any buildup of rust, corrosion or old
rubber with wire brush.
CAUTION
Never mount a tire on a rim where any parts
show cracks, damage, or have been repaired
by welding or brazing. Thoroughly inspect
inside of casing for damage or foreign mate-
rial. Make sure that the tire is completely dry,
as moisture deteriorates the cord fabric of the
tire and may result in eventual failure of the
tire. Lubricate both beads with an approved
rubber lubricant. Never use silicones, anti-
freeze, or petroleum base solutions.
2. Lubricate Rim: After inspecting rim, thoroughly
lubricate both bead seats with approved tire lubricant.
3. Lubricate Tire Beads: After inspecting tire thor-
oughly, lubricate both beads inside and out with an
approved lubricant.
