Tyre Maintenance
01 Check the tire regularly
Always check the tire you are using
When checking tires, including the spare tire should be checked, and check the tire pressure. Found that drums, cracks, cuts, nails and abnormal tread wear phenomenon. The use of damaged tires may result in tire damage. Driving a vehicle on a road with potholes and rocks or other objects may damage the tire and make the vehicle poorly positioned. Therefore, when driving on such roads, it is necessary to travel slowly and carefully. After these sections, check whether the tire has Any damage, such as cuts, drums, nails, abnormal tread wear and so on.
Check tread pattern regularly
Check the tread depth regularly and replace the tires when they are worn to a certain extent. This will ensure maximum tire traction and grip while preventing any unpleasant accidents.
The safety of the vehicle depends on the preferred tread depth for the following reasons:
The role of the tread pattern is to discharge the water under the tire to keep the vehicle control
Tread pattern, the more wet road, the occurrence of "drift phenomenon" the less likely
Proper tire pressure and regular maintenance will ensure that your tire has the longest life and the best performance
Tread grip strength, the impact of your vehicle's braking distance
02 Note tire pressure
Proper inflation is critical to tire performance and longevity, as well as to the driving experience and safety of the vehicle. Tires carry the full weight of the vehicle, and when inflated or inflated excessively, they do not work properly. The use of tires in under-inflated conditions can also result in tire damage.
Check the tire pressure once a month
• A passenger car tire inflated to 260 kPa may miss 7.5 kPa of pressure per month.
• Check tire pressure for all tires, including tire pressure, before traveling. Note that tire pressure needs to be checked in a "cold" tire condition.
• Also, do not forget that the spare tire also needs to maintain the correct tire pressure
Recommended tire pressure
If you do not know the correct tire pressure is how much should be how to do?
Very simple. The following information can be found on your vehicle:
• In the vehicle user manual.
• Stickers on the passenger car door.
• Storage drawer next to the driver's cab.
• Cylinder cover door.
The tire manufacturer's recommended tire pressure data do not appear on the tires. The inflation pressure shown on the sidewall of the tire is only the maximum inflation pressure in the case of tire cooling.
How to Check Tire Pressure Correctly
1 Please purchase a high quality tire pressure gauge and check its accuracy at the Michelin tire retailer.
2 Check the tire pressure in the "cold" tire condition - that is, after the vehicle has traveled no more than 2 km, or at least three hours after the stop.
Valves and valve caps
To ensure proper tire pressure, tire valve maintenance is very important. The valve is usually made of rubber, so it will age with the passage of time. When you buy a new tire, the valve also needs to be replaced. At high speeds, the broken rubber valve stem may buckle under centrifugal force, causing a leak.
The valve cap is also a very important part. When the valve core for various reasons, failure, high-quality valve cap helps to maintain tire pressure. Valve cap can also block moisture, moisture into the tire may freeze and compress the valve core, leading to leakage. In addition, the valve cap can also block dust particles, to avoid its impact on the valve core, leading to leakage.
The harm of insufficient air pressure
Insufficient air pressure will cause tire sidewall deformation, heat increase, greatly reduce the tire life, and will bring the following problems and security risks:
(1) excessive wear shoulder position
(2) increase the possibility of the tire hit the drum
(3) the tire adhesion between components decreased lead to delamination
(4) a serious shortage of air pressure caused by sidewall crushing damage
(5) the tire beating is too large, resulting in bead between the rim and the abnormal wear and tear, damage bead
(6) rolling resistance increases, fuel consumption increased
Pressure over the hazards
Over-pressure will lead to tire tread grounding area decreases, increased rigidity of the matrix, reduce the buffer, and will bring the following problems and security risks:
(1) tread center excessive wear
(2) increase the tire by external shocks even when the risk of bursting
(3) reduce the grounding area lead to decreased handling, prone to flick, taxi and other dangerous
(4) ride comfort decreased
(5) long-term pressure over foot driving, easy to cause harm to the vehicle chassis
03 Dynamic balance
After tire installation, the dynamic balance can compensate for the weight of the tire and rim combination. When a part of the weight is greater than or less than other parts, the wheel will lose balance. This can lead to irregular tread wear and body jitter, increase the pressure on the front end components, leading to premature wear.
Why is balance adjustment so important?
When the weight of one part of the wheel is greater or less than the other parts, the wheel is out of balance. this will:
• Uneven wear of the tread
• Causes body jitter
• Increases the pressure on the front part
• Leading to premature wear of the front part
When should the wheel balance be adjusted?
Adjust the wheel balance in the following cases:
• After replacing the tire
• After moving or removing one of the weights
• Buy new tires
• After tires have been repaired, it is necessary to re-balance
One tip: Once you find the body jitter or tread abnormal wear and tear, please check the wheel balance and four-wheel positioning, and find whether there are mechanical parts wear or damage.
04 Wheel alignment
Four-wheel positioning usually refers to adjusting the front and rear suspension components of a vehicle. Proper four-wheel positioning helps ensure proper handling of your vehicle and helps increase tire life and performance.
Why is four-wheel positioning so important?
The correct four-wheel positioning helps to ensure proper handling of your vehicle and helps improve tire performance. Poor wheel alignment can also result in irregular tread wear and shortened tire life.
When should I check the wheel alignment?
In the case of potholes, trains, and other everyday impacts, or even more serious accidents such as traffic accidents, your vehicle's four-wheel positioning may be bad. Check the four-wheel alignment in the following cases:
Driving hit other objects
Abnormal signs of wear are seen on the shoulder
Found that abnormal vehicle control situation
In a small tip: vehicles traveling 8000-10000 km, it is recommended to do a four-wheel positioning
05 Tire transposition
In order to obtain uniform wear and tire maximum mileage, tire transposition is necessary. It is advisable to replace the tires each time the tires are used for about 10,000 km or there is uneven wear or abnormal wear on the tires. Some tire side of the tire with arrows indicate the direction of rotation, when the transfer must be considered when this factor, according to the direction of the arrow to adjust the direction of rotation.
06 Tire repair
Tires must be removed from the wheel rim, checked by a professional tire vendor before deciding whether to repair
Tire can not be recommended to repair the following conditions:
Damage to the sidewall can not be repaired
The diameter of the hole penetrating the crown can not be repaired beyond 6 mm
If the bead is damaged or deformed, the tread is deformed, the rubber is corroded by the chemical, or the tire is run flat.
07 Avoid bumping obstacles
When the vehicle is moving at high speed, such as a tire hitting potholes and other obstructions can cause the tire to cause serious extrusion deformation between the obstacle and the flange of the rim. This can cause the carcass cords to break and the compressed air inside the tires to break. Line from the top of the formation of drum kits. More serious, it will cause the tire impact rupture, tire suddenly discouraged.
If you can not avoid the obstacles, please try to slow down the passage. If you can not avoid the obstacles, please try to slow down. Tires with low sidewall height are especially important!
08 Avoid tire runaway
When the vehicle is stuck in the mire / sand / snow, we usually step on the gas pedal to enable the vehicle to leave. However, please remember: Do not let the tire speed too high, because the speed is too high centrifugal force, will eventually lead to a sudden rupture of the tire and dangerous.
One tip: No one should stay near an idling tire to prevent a sudden break of the tire from injury.
09 Tire replacement
Tires After the following conditions, the proposed replacement of tires:
1, tires pattern to reach the wear instructions. The wear indication marks the minimum allowable tread thickness. (Not less than 6 circumferences in the tread groove and 1.6 mm in the sidewall with "△" pattern), tires with a tread wear can not be well drained, and are prone to slippage or wetting Road slippage and other dangerous situations. Puncture the situation even more frequently.
2, hit the shoulder, into the hole or insert nails serious damage to your tires. Tires can not be repaired properly by a professional tire dealer.
3, if there is a significant tread deformation or cracking of the phenomenon, please stop using these tires immediately. The professional tire dealer to check, determine the tire can not continue to use.
