These are very important considerations for comfortableness and maximum mileage from
your tires. Check how your tires are wearing at least once a month. If your tires are wearing
unevenly, such as the inside shoulder of the tire wearing faster than the rest of the tread,
your vehicle may be out of alignment.
This condition not only shortens the life of your tires but also adversely affects the handling
characteristics of your vehicle which could be dangerous. If irregular wear is indicated, have
your alignment checked immediately. Tires which have been run underinflated will show more
wear on the shoulders than in the center of the tread.
Such underinflation may cause damage to the tire structure.
Have the tires inspected by your dealer.  

The maximum load capacity and air pressure of your tires is marked on the sidewall.
Do not exceed these limits. Following the loading instructions of the manufacturer of your
vehicle should insure that your tires are not overloaded. Tires which are loaded beyond their
maximum allowable loads for the particular application will build up excessive heat that
may result in sudden tire destruction.  

It's the indication of the maximum speed when driving on the smoothly-paved road after the installment of the tire.

Tire Pressure
Measure the tire pressure when the tire is cold and inflate to originally specified pressure.

Tire Wear
Minimum tread depth is limited to 1.6mm.
There are 6 ?on the circumference of the tire marked ”remaining tread”

Caution
Check the tire surface for cracks, pins, metal scraps, glass or anything that may puncture the tire. Also, check for pebbles stuck between the treads. If any of the above situations occur, please go to a professional tire shop for repair.
Mounting a tire to rim should be following the instruction of direction.
The tires should be rotated according to specifications.
If the tire crown is abnormally worn (damage), please go to a professional tire shop for replacement.
Avoid direct sunlight, rain, oil, and electric sparks in tire storage locations.

Check point
The tire is made of rubber and will deteriorate after a long period of use, and should be periodically inspected. Nankang doesn't guaranty tire whichever five years off from manufactured date the tires should be inspected regularly by the shop; tire over 10 years old must be replaced.

Noted
Avoid grinding the sidewall against the curb and running over bumpy surfaces, to limit damage to the tires.
Avoid sharp cornering, quick stops, and rapid acceleration, to prevent accidents from happening.
Keep a safe driving distance and obey the speed limit.
When you feel vibration from the vehicle or steering wheel, inspect the tires or return them to the factory for a checkup.

 

Tire pressures, including the spare, should be checked at least once per month before
driving, when the tires are cold (after thevehicle has been stopped for three hours or
driven less than one mile).
Do not reduce air pressure when tires are hot.
Use a tire gauge to check pressure and maintain it at the level recommended by
the vehicle manufacturer. If a tire loses more than one pound of air pressure per month,
have it checked for leakage by your dealer.
Proper inflation pressure is very important to tire durability tire life, comfortableness,
and vehicle handling, therefore you should always maintain the correct inflation pressure in your tires according to
your vehicle manufacturer?s recommendation.
In addition, your vehicle has a Tire Information Placard, which indicates the proper tire size
and inflation pressure for your particular model car.
