WARNING
• Do not use a tubeless tire on a wheel de-
signed only for tube tires to avoid tire fail-
ure and personal injury from 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 the
wheel rim band and tube are centered in the
wheel groove.
• Patching a punctured tube is not recom-
mended. If it is absolutely necessary to do
so, use great care and replace the tube as
soon as possible with a good quality re-
placement.
