sudden deflation.
• When using a tube tire, be sure to
install the correct tube.
• Always replace a new tube tire and a
new tube as a set.
• To avoid pinching the tube, make sure
that the wheel rim band and tube are
centered in the wheel groove.

ommended. If it is absolutely neces-
sary to do so, use great care and
replace the tube as soon as possible
with a good quality replacement.
