1.Air Pressure
★ Proper inflation is the single most important factor in tire care. If pressure is high, tire tread will be easily worn and may burst; if low, tire is easy to deform and may crush
★ The inflation pressure imprinted on the sidewall of the tire is the maximum operating pressure determined by the tire manufacturer.
★ Recommend checking air pressure once a month and before long trips.
★ Always check the pressure when the tires are "cold"
★ Don't forget to check the spare tire.
★ Replace valves when you buy new tires.
★ When mounting the twin tires, the air pressure of them must be same

2.Rotation
★ Regular rotation extends the life of your tires, saving you time and money in the long run.
★ Each tire and wheel is removed from your vehicle and moved to a different position. This ensures that all of the tires wear evenly and last longer. If no period is specified in your owner's manual, the tires should be rotated every 6,000-8,000 miles.

3.Alignment
★ Alignment generally refers to the adjustment of a vehicle's front and rear suspension parts.
★ Proper alignment ensures that your vehicle handles correctly and will help increase the life and performance of your tires.
★ The alignment of your vehicle can be knocked out of adjustment from daily impacts such as potholes and railroad crossings, or by more severe accidents.
★ You should have the alignment checked if:
You know you have hit something.
You see a wear pattern developing on the shoulders of the tires.

4.Balancing
★ Balancing means compensating for both the weight of the tire and wheel after the tire is mounted. A wheel is out of balance when one area is heavier or lighter than the rest. This can cause irregular tread wear and vibration, and increase the stress on the front-end parts, which may cause them to wear prematurely.
You should have your wheels balanced whenever a tire is replaced, when a balance weight is moved or removed, and whenever you purchase new tires. Of course, at the first sign of vibration or irregular tread wear, your car should be thoroughly checked for wheel balance and alignment, and for worn or broken mechanical parts.

5.Vibration
★ A vibration while driving indicates a problem that needs attention.
★ The tires, steering system and suspension system should be checked immediately to help determine the possible cause of the vibration.
★ If the vibration is not corrected, it could cause excessive tire and suspension wear - it could even be dangerous.

6.Treadwear Indicators
★ All tires have treadwear indicator bars at 2/32" of remaining tread.
★ When the tread is worn down to 2/32" or where you can see the treadwear indicator bars on any section of you tire, the tire is worn out and should be replaced.

7.Driving Habits
Here are some tips to help increase the life of your tires:
★ Don't speed. Excessive heat is generated when driving at high speeds. This heat increases the rate of tire wear and reduces the tire's durability. Avoid fast turns on curves and around corners, and avoid fast starts and panic stops.
★ Don't ride on the edge of the pavement or drive over curbs, potholes, or other obstructions.
★ Don’t overload, overloading will cause early damage of tires even puncture
