WARNING
_
• Do not use a tubeless tire on a wheel
designed only for tube tires to avoid tire
failure and personal injury from sudden
deflation.
• When using tube tires, 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.
