| “Through a thousand miles, starting under the ‘tire’ ”, the importance of tires to vehicles is just as important as the shoes are to us. Car maintenance first is to care the car tires. Car tire experts summarized the three major issues of regular tire maintenance, hoping to help the majority of car owners. |
 |
| Balance cannot be ignored |
| |
| Many attentive friends may find that there are one or more small lead blocks of different sizes on the edge of the hub. These humble small lead blocks play a very important role in the stability of the car at high speeds. When you find that the steering wheel is shaking when the vehicle is driving at high speed or you have some kind of rhythmic noise on the wheels, it may be that the wheels need to be balanced. Especially when changing tires, wheels, or tires, if the wheels are subjected to excessive impact, and the balance weights are lost due to bumps, the wheels should be balanced. |
| |
| The car wheel is made up of tires and hubs. Since the mass distribution of each part cannot be very well-distributed, and the tires and hubs are not absolutely round, when the wheels rotate at a high speed, they will produce a yaw or bounce, the driver will feel the wheel shaking, steering wheel vibration phenomenon. In order to avoid and eliminate this phenomenon, it is necessary to make the wheels balance the balance of each edge portion of the wheel by adding weights under dynamic conditions. This correction process is called dynamic balance. In general, a balance of three months or 5,000 to 8,000 kilometers is required. |
 |
| Tire replacement should be remembered |
|
| Since the working conditions and loads of the tires are not the same, the driving wheel load is greater than the non-drive wheel (currently, the ratio of the front wheel drive of the car is much higher than that of the rear wheel drive), plus the right wheel load is greater than the left wheel . So when the car is driving a certain distance, different parts of the tire will have differences in fatigue and wear. Therefore, tire replacement should be performed in time according to the automobile maintenance regulations. In particular, the new car after the initial transition, a great impact on the service life of the tire. |
| |
| Tire transposition is divided into transposition and cyclic transposition. Cross-positioning is suitable for cars that often travel on large arched roads. Cyclical transposition is suitable for cars that often travel on relatively flat roads. For a typical front-wheel drive or rear-wheel drive vehicle, the cycle of tire repositioning is the same as the cycle of dynamic balancing. It can be done every three months or 5000-8000 kilometers, but the cycle of four-wheel-drive models will be Appropriately shortened. |
 |
| Four-wheel positioning |
| |
| During driving, if you find heavy steering, trembling, deviation, inconsistency, non-returning, or a sense of floating, jolting, swaying, etc. during driving, this is to remind you that the car needs to do four-wheel alignment. Now. In fact, when the tire has unilateral wear, wave wear, block wear, eccentric wear and other abnormal wear, you should go to the 4S shop to do four wheel alignment. |
| |
| The role of four-wheel positioning in addition to the vehicle to maintain a stable straight line and steering light, but also reduce the wear and tear of the tires and steering parts in the car. The contents of the four-wheel alignment summed up in the four-character “three-ply bundle” – the kingpin caster, the kingpin caster, the front camber, and the front toe. For a vehicle traveling 10,000 kilometers, a four-wheel alignment is generally required. |
| |
| Finally, to remind owners, regular maintenance of tires is the key. We also remind car owners here to make a comprehensive inspection of their car tires before traveling by car. This is a powerful guarantee for you to “go with pleasure and drive home happily”. |

| How to deal with emergency situations |
| |
| Even if the vehicle is properly maintained, it is impossible to completely avoid problems and breakdowns in self-driving travel. For tires, the most dangerous situation is to have punctures and sideslips. |
| |
| Puncture |
| |
| There are many cases of front tire puncture during driving. Do not panic in this situation, remember not to step on the brakes! Hold the steering wheel firmly with both hands, control the vehicle as much as possible, and apply the brake pedal lightly as much as possible to avoid too much force on the front part, because the front tire that bursts will roll unevenly and may even get out of the rim. Hold the steering wheel firmly with both hands so that when the car is moving to the left or right, it can be corrected immediately. |
| |
| If there is a puncture in the rear, there will be irregular and violent shaking of the tail of the car. The driver needs to stay calm and he can’t step on the brakes! Hold the steering wheel with both hands and keep the car straight. In addition, it is best to use a point break so that the center of gravity of the car can be moved forward and the tires are not locked up. The intact front tires should be forced as much as possible to reduce the load on the burst rear tires. |
 |
| Car sliding |
|
| In the event of a sideslip, stop the brake immediately and reduce the throttle. At the same time, turn the steering wheel to the side that slides sideways. Do not overdrive or force the direction for too long. Otherwise, the vehicle may slide in the opposite direction. Because the brake is stopped, the wheel is released from the locked state, so that the lateral adhesion is improved. Turning the steering wheel toward the side-slide direction increases the turning radius of the car and reduces the centrifugal force. After the car is turned back, it must steadily turn the steering wheel to its original position. |
| |
| Do not use the brake when sliding sideways. Manually apply the model to keep the clutch engaged. Use the engine brake to decelerate. The automatic transmission model must release the throttle. In order to prevent slippage, the speed of the vehicle must be slowed down, and the speed of the road cannot exceed the prescribed speed. When starting on a slippery road, every start, stop, and turn must be slow, which reduces sideslip. When using the brake, use a point break to prevent the vehicle from being braked. |
