Tire Repair
CAUTION
When replacing tire, take extra care not to damage
tire bead, rim-flange and bead seat.
Install tire, noting the following items
a. Install valve core and inflate to proper pressure.
Check
the locating rings of the tire to be sure
they show around the rim flanges on both sides
b. Check valves for leakage after inflating tires.
c.
Be sure to tighten valve caps firmly by hand
WARNING:
When, while tire
is being inflated, bead snaps
over safety hump,
it might break. Thus, to avoid
serious personal
injury, never stand over tire when
inflating it Never inflate to a pressure greater than
40 psi (275 kPa). If beads fail to seat at that
pressure, deflate
the tire, lubricate it again, and
then reinflate it. If the tire is overinflated, the
bead might break, possibly resulting
in serious
personal inlury.
