Wheel and Tire
Tire
Remark
This vehicle's tire is of the tubeless type. The optimal design condition is met when the inflation pressure is at
the recommended value, and the tire is under full load. Maintaining suitable tire pressure and proper driving
habits greatly influence the tire's use life. For the vehicle, it improves riding comfort, stability, and handling. For
the tire, it reduces tread wear, damage to the tire and extends tire life. Overloading, speeding, and unnecessary
emergency braking will all add to the tire's wear and tear.
Tire pressure measurements should be taken under normal temperature. If the tire pressure rises due to motion
generated heat when driving, cooling it will return to the normal temperature. Therefore, do not deflate the tire
when the air pressure has risen to this point. The tire's air pressure will naturally and slowly decrease when used
under normal conditions. Hence please inspect the air pressure regularly (suggested once a month). The spare
tire should be kept in a useable condition at all times.
Inspect the tire pressure when it is cool monthly or before a long drive. Adjust the tire pressure to the recom-
mended level. The air pressure will normally rise because the tire warms up due to movement. Therefore, after
driving, you absolutely must not deflate or reduce the tire's air pressure, as deflating could reduce the cool tire's
air pressure.
Tire inflation
During a new tire's initial stage of use, warning due to bending motions will cause the tire to swell, and thus
reduce the corresponding air pressure. After 24 hours or 2000-3000 km worth of drive, charge the air pressure.
After inflating, check if the air nozzle core is leaking air with soapy \
water, then lock on the cap.
Possible problems caused by tire pressure
Exceeding the recommended air
pressure
Below the recommended air pressureSame vehicle axle, different
air pressure
Possible problems it
can create
1. Bumpy ride
2. The tear or rupturing of the tire
3. Rapid wear of the tire tread's center
1. Noisy turns
2. Uneasy turns
3. Tread edge wear is accelerated and uneven
4. The tire's rim is damaged or ruptured
5. The tire cord ruptures
6. High tire temperature
7. Steering failure
8. Large oil consumption
1. Uneven braking
2. Over steering
3. Steering failure
4. Deviation while accelerating
Tire and wheel (steel wheel) installation instructions
When installing the tire and wheel, the tire's radial hardware components, also called "high spot", should be at
the same level of the wheel's minimum radius or so called "low spot".
The "high spot" of the tire is initially marked by the paint spot on the side of the tire's surface. This paint will
eventually be washed away.
The "low spot" of the wheel is initially marked by a paint spot on the wheel flange. Whenever the tire is
removed from the wheel, the tire and wheel need re-balancing to make sure the vehicle runs smoothly. If no
paint spot is found on the tire, draw a line on the tire and the wheel before they are removed, in order to make
sure that the tire and the wheel will be re-assembled at the same place.\

Tire replacement
When a tire needs to be replaced, make sure to use a tire with the same specification as the original one. A new
tire used for replacement must be of the same dimension, load area, and structure as the original one. Using tires
that are different in dimension or type will influence the vehicle's riding comfort, handling, speedometer and
odometer calibration, vehicle ground clearance, and the clearance between the tire or the tire's snow chain and
the vehicle body or chassis.
It is suggested to use a new pair of tires on the same axle. If only one tire is needed to be replaced, make sure to
use a tire with a tread most similar to the original, so as to keep brak\
e power and traction balanced.
Warning: Do not mix radial tires, bias tires, bias belted tires, etc., which are of different structure on the
same vehicle unless it is an emergency. Mixing different tires would seriously influence the vehicle's
handling and stability, and even possibly lead to losing control of the vehicle.

Wheel
General tire balancing procedures
Clean out the accumulated dirt and debris from the inside of the rim.
Warning:
The gravel on the tread must be eliminated to avoid flying out and injuring the operator when
undergoing rotational balancing. This is also a good way to acquire better balance. First thoroughly
inspect the tire's damaged condition, then according to the balancing device manufacture's
recommendations, carry out the balancing operation.
Off-vehicle balancing
Most off-vehicle balancers are more accurate and convenient than on-vehicle rotational balancers. They are
also able to perform dynamic (two sided) balancing. Although it does not correct drum brake and brake disc
imbalance like on-vehicle balancing, it achieves the same effect based on its accuracy.
On-vehicle balancing
On-vehicle balancing is different based on equipment and tool manufacturer. Therefore, when performing
balancing operations, be sure to comply to each manufacturer's operating\
instructions.
Warning: Control the wheel rotation speed to make sure the speedometer stays within 55 km/h.
This restriction is necessary because when a driven wheel slides while the other one stays still, the
speedometer will display only half of the actual wheel speed. When a wheel is sliding, be extremely
careful, because sliding wheels can reach very high speeds. This may lead to the tire rubber peeling
or differential damage, which may cause serious personal injury, or damage to the vehicle.
Tire installation and removal
• Install or remove tires with a tire changer. When operating machinery, make sure to comply to the machine
manufacturers operation manual. Please do not change tires merely with manual hand tools or tire installation
crowbars. This will damage the tire chafer or the vehicle wheel's rim.
• Use a wire brush or coarse steel wool to clean off grease and old rubber, as well as light rust or corrosion from
the rim tire bead's tire chafer seat. Before tire installation or removal, first use the indicated tire lubricant to
thoroughly lube the tire chafer portions one time.
• After installing the tire, inflate it to the specified pressure and make\
sure the tire bead is properly seated.
Warning: Do not over-inflate the tire. If the tire bead severally expands and exceeds the safety limit,
it may burst and cause serious personal injury. While inflating, do not exceed the specified pressure.
If the specified pressure does not allow the tire bead to sit properly, deflate the tire, re-lubricate, and
then re-inflate.
Spare tire usage
• Spare tire standard inflation pressure: 420 kPa.
• Spare tire pressure measurements should be taken under normal temperatur\
e conditions.
• After inflating the spare tire, soapy water should be used to check if the air nozzles core is leaking air, then
lock on the air nozzle cap.
• The spare tire should always be kept in a useable state. Check the air p\
ressure at least once a month.
• When the spare tire's working limit, indicated by the remaining pattern's depth, reaches 1.6 mm (and its pat-
tern groove bottom protrudes to the same level), for your safety, please stop using the spare tire.
Caution:
• The "" symbol on the tire bead of the spare tire in-
dicates the set position of the wear index (shown on
the left).
• The spare tire's maximum driven speed is 80 km/h,
and maximum distance 200 km per trip.
• Each vehicle is allowed to use only one spare tire.
• The spare tire is only used as a temporary backup.
Please go to a professional service station immediately
to get the initial tire repaired or replaced.
