Special instructions
Some types of wheels on the market require
special procedures and precautions which
differ from the standard procedure.
This applies in particular to the following
types of wheels:
Alloy rim wheels: some wheels have alloy
rims where the drop centre A is very small
or non-existent - fig. 11-B. These rims are
not approved by the DOT (Department of
Transportation) standards - these initials
certify that tyres comply with the safety
standards adopted by the United States
and Canada (these wheels cannot be sold
in these markets).
DANGER
Take utmost caution when mounting the
tyre. The rim and/or the tyre may be da-
maged accidentally, with the risk of the
tyre exploding during the inflation stage.
European style high-performance wheels
(asymmetric curvature) - fig. 11-C: some
European wheels have rims with very pro-
nounced curvature C, except in the area of
the valve hole A where the curvature is less
pronounced B. On these wheels the bead
must first be broken in correspondence with
the valve hole, on both the top and bottom
sides of the wheel.
Wheels with low pressure indicator system -
fig. 11-D: see the chapter on "Procedures for
wheels fitted with valve or strap-on sensors"
NB:
When working on "weak" rims (i.e. a central
hole with thin, projecting edges - see next
figure), or rims with gaps, we recommend
using the universal turntable for blind rims
accessory.
