Description
The safety
rim
wheel (Fig. 1) has raised sections
between the rim flanges and the rim well. Initial in-
flation of the tire forces the beads over these raised
sections. In case of a blowout, the raised sections tend
to hold the tire in position on the wheel, until it can
be brought to a safe stop.
Tubeless tires have a uniformly smooth bead con-
tact area in order to form an air seal with the wheel
rim. Any foreign matter, lodged between the tire bead
and rim, may cause an immediate air leak or the for-
mation of rust which will eventually cause an air leak.
Wheel covers should only be removed and installed
in the recommended manner to eliminate possible
damage.
Front wheel bearing lubricant should be changed
at the recommended intervals or at the time of a nor-
mal brake reline. Lubricant should not be added to
that already in the bearings.
