Tire and Rim Maintenance
Tire is an important part of the wheel to contact the ground. The tires with incorrect condition and size and the rim with wrong spoke tension will affect

the driving performance and cause losses.
● Abnormal tire pressure will reduce the
service life of tires, too low pressure will make
it difficult to turn, resulting in abnormal tire
wear and overheating, and too high pressure
will reduce the contact area between the tire
and the ground and make it easy to slip or get
out of control.
● Correct tire pressure can provide the best
riding comfort and extend the service life of
tires.
Correct tire pressure
Front tire 225Kpa
Rear tire 225Kpa
If the tire pressure is not as specified:
Correct the tire inflation pressure when the tire
temperature is in line with ambient
temperature.
Check the spoke tightness.
● If the spokes are too tight, they will break
when overloaded.
● If the spokes are too loose, the wheel will
run sideways or radially jump, further
loosening other spokes.
● Check the spoke tension regularly with a
suitable tool at the site of CAOFEN distributor.
Acceptable spoke sound: crisp and consistent
Unacceptable spoke sound: irregular sound
indicates that there is a difference in spoke
tightness.
Check the torque of the spoke:
Inner joint of front wheel
spoke
6Nm
Inner joint of rear wheel
spoke
6Nm
Check the tire
pressure with a
pressure meter
Check the tire pressure
which should be
measured in a cool state
Scratch or tap the spoke
with a tool such as a
screwdriver
