Demounting / Mounting; Fundamentals
6. Fundamentals of demounting and
mounting a tire
1
Use the special plastic parts for clamping, the
plastic mounting head and special tire levers
(coated or the like) so as not to damage the
rims, in particular alloy rims, when mounting or
demounting the tires.
2
Prior to demounting or mounting a commercial
tire lu-bricant should be applied onto the bead
outer and inner sides, the rim flanges and
shoulders, and the Denloc groove with TD tires.
Never use other agents only supposed to
lubricate!
3
Prior to demounting or mounting of a tire check
the rim for damage (deformation and/or
damaged surface of rim flanges, lateral and
radial run-out of rim, corrosion, wear in general).
4
With some tire types, pay attention to the outer
sidewall rib, or to direction of rotation as
indicated on the tire.
5
When inflating the tire increase pressure
gradually and possibly by constantly observing
the bead. A seating pressure of 3.3 bar should
not be exceeded. Make sure the mounting
guide rib of the tire is correctly seated with
respect to the rim flange. A final pressure of
3.5 bar should not be exceeded (also refer to §
10. Inflating tires).
6
Always fit tires on rims of proper size (identical
nominal diameter); this means for example no
tires of nominal size in mm on rims of nominal
size in inches and vice versa.
7
No tubes may be fitted in TD tires.
8
At any rate pay attention to special mounting
and de-mounting instructions by tire makers.
