Scott TIME TRIAL MACHINE Owner's Manual page 73

Clincher and folding tyres and rim alone are not able to hold the air. Therefore,
an inner tube has to be placed inside the tyre (f) to retain the air pressure.
Rims of clincher and folding tyres require in general a high-value rim tape over
the complete width of the rim base. This rim tape protects the inner tube from
the braking heat which could make the tyre burst.
In the case of tubular tyres that must be glued on the rim the tube is already
integrated into the tyre and can be neither removed, nor patched in the case of
a puncture. This type of tyre requires special rims without rim flanges.
If necessary, read the respective manuals before working on such kind of tyres.
Tubeless tyres can only be used in combination with specifically de-
signed wheels. Pay attention to the manufacturer's type designations (e.g.
"2way-fit"/"tubeless ready").
With reduced pressure tubeless tyres can be used as clincher tyres. The ap-
propriate pressure for 75-kg / 165-lbs-cyclists is usually 7 bar and for 65-kg /
143-lbs-cyclists 6 bar. Make sure the pressure is not below 4.5 bar. Observe the
marking on the tyre sides regarding the maximum pressure.
WARNING
Replace tyres with a worn tread or with brittle or frayed sides. Dampness
and dirt penetrating the tyre can cause damage to its inner structure. The
tube might burst. Risk of falling!
If you mount a new tyre with another size than the standard tyre mounted,
it might be possible that the clearance between the front of your shoe and
the wheel will be reduced when you ride at reduced speed. Also observe the
space between fork and frame. Risk of accident!
