Mounting of
tubed tires
6-3
When mounting Alcoa flat base wheels for tube-type tires you must use the proper side
ring or side and lock ring required for each wheel. The table below lists the Alcoa tube-type
wheels currently in production and the proper side ring or side and lock ring identification
recommended for each wheel. See the Multipiece Rim Matching Chart on page 39 for
information on older wheels with part numbers not shown here.
Lubricate tube, flap and wheel. Insert tube and flap
into tire. Place them on the wheel so that the valve
is aligned with the valve slot.
Place side ring on wheel and tire and stand on the ring
to position it below the lock ring groove. If a split side
ring is required, start the leading edge and walk the side
ring onto the wheel
Seat the second end of the split side ring or lock ring
with a rubber, plastic or leather-facet mallet as shown.
Check carefully to see that the split side ring or side ring
and lock ring assembly is in the proper position. If not,
completely remove the components and start over. Inflate to 10 psi. Check to see that all components
are properly in place. If not, deflate the tire by removing
the valve core and reposition components properly.
Place in a safety cage or other suitable restraining
device (refer to OSHA rule 1910.177, paragraph B,
see Section 7, page 44). Use clip-on chuck and stand
behind barrier during inflation. Do not lean on cage.
Inflate to recommended pressure. Deflate completely
to avoid localized over-stretching of the tube. Reinflate
to the tire manufacturer’s recommended pressure.
If the wheel requires a lock ring, start the leading edge
of the lock ring being sure that it is seating in the
machined groove. Then walk the lock ring onto the
wheel, as illustrated

which does not affect the compatibility of parts as shown in the table.
