WARNING: Tire wear, punctures, or ruptures can cause immediate loss of
control, which may affect operator and precipitate serious bodily injury.
Helmets, goggles, gloves, elbow and knee pads and appropriate shoes with
ankle support must be worn at all times.
WARNING: Completely deflate wheel before disassembly or any work on the
wheel. Failing to do so can result in serious injury.
WARNING: Patching a tube is an emergency repair. Patches can severely
weaken the integrity of a tube, resulting in possible tube failure and cause a
loss of control. Replace a patched tube as soon as possible. Never replace the
tube with anything other then the stock OEM tube. Using an aftermarket tube
or tire not intended for PROGO® specifiation could result in a sudden loss of
pressure that could cause damage to your scooter and sudden loss of control.
Never use a tube or tire that is not recommended by PROGO®.
CAUTION: Replace front or rear tires when tread is worn within 1/16” tread
depth, or if obvious tire damage has occurred.
