Principles
lToavoid damage when mounting and demounting
tyre, especially the alloy ones, use the tyre lever
offered by manufacturer.
lFor easier demounting and better protection of the
tyre and rim, lubricate the area between the rim and
tyre bead, where thebead breakershoe goes in,
with industrial lubricant or thick soap solution.
lCheck for damages (distortions, surface damages,
excessive runout, erosion or overall wear) before
demounting.
lPay special attention to rotary direction marked on
some flanges or tyres.
lFit the tyre on the rim of matched size.
lNever ignorethe mounting anddemounting
requirements of the special wheel.
lWhen inflating thetyre, make surethe pressure
increases in an even way.Pay attention to status of
the tyre bead.
Demounting Tyre
Preparing
lDeflate the tyre thoroughly.
lRemove all the foreignsubstance andweights from
the rim (Fig. 03).
