peCial 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 damaged ac-
cidentally, with the risk of the tyre exploding
during the inflation stage.
European style high-performance wheels
(asymmetric curvature) - fig. 11-C: some Eu-
ropean wheels have rims with very pronounced
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.
