4、Points of attention for the rim sections and tires
（1）Do not use the under-standard rim sections or tires;
（2）The aluminum alloy rims are easy to be damaged by scraps. Please use soft cloth
when doing the cleaning. Never try to use steel brushes. If steam is used for cleaning the
car, do not allow the boiling water to contact the rim sections;
（3）In the case that some alkali chemical compounds (such as mud water, road surface
mud, etc.) stain on the aluminum alloy rim sections, use the neutralizing agents to clean
them off as soon as possible so as to avoid the rim sections from being damaged.
5、Tire replacements
（1）Before installing the air valve nozzle, first check to see if the air valve opening on the
tire is smooth and free of rags. Then apply some glycerin onto the surface of the air valve
nozzle rubber or dip the air valve nozzle in the glycerin. Use the special tools to exert the
air pressure of 200—400N so as to allow the positioning ring of the air valve nozzle to pass
the hole on the wheel which complete the installation and positioning (soap solution can be
used to substitute glycerin);
（2）Before installing the tires, apply glycerin or soap solution along the tire rings. Make
sure that when there are light indication spot marks on the rims, the test marks for tire
balance should be aligned with these light indication spot marks. When there are not light
indication spot marks on the rim, the dynamic balance test marks of the tire should be
aligned with the air valve nozzle position. If there are neither light indication spot marks
on the rim nor dynamic balance test marks on the tire, but there are static balance test
marks on the tire, make sure that the air valve nozzle is aligned with the static balance test
marks.
6、Tire pressure
Check the air pressures of all the tires (including the
spare tire) with the barometer. Make proper adjustments
if the air pressure does not meet the specifications. Strictly
follow the specified air pressure in filling the tires with air.
During the air filling, the air pressure should not exceed the
nominal air pressure by 10 %. The tire with filled air should
be placed separate from the wheel mounted on the car. Before
doing the positioning of the four wheels, please check the air
tyre
pressures of the four wheels and make proper adjustments
air hole
so as to meet the specified air pressure.
7、Air leakage
Make sure there is no air leakage at the air valve.
