In fact, the contact area between the tire and the road is only the size of a person's palm, but your safety, comfort and fuel economy all depend on this very small tread, so how to maintain the tire has become a top priority. In daily life, we can refer to the following points:

① Four wheel alignment

Correct four-wheel alignment helps to ensure the normal operation of your vehicle and improve the performance of tires. Poor wheel alignment will also lead to irregular tread wear and shorten the service life of tires.

② Tire alignment

In order to obtain uniform tire wear and prolong the service life of the tire, tire alignment is necessary. The standard of tire alignment is generally subject to the guidance on tire alignment in the vehicle manufacturer's user manual. For vehicles equipped with new symmetrical pattern or asymmetric pattern tires of the same specification (whether front drive, rear drive or 4WD vehicles), each tire alignment is generally carried out every 8000-10000 km, but if uneven wear is found on the tread (common on the driven wheel), It is necessary to carry out the cross transposition of the front and rear wheels as soon as possible and in time. If the specifications of the front and rear axles of the original tires of the vehicle are different, it is not allowed to adjust the position between the front and rear axles.

③ Tire repair

The tire must be removed from the rim and checked by a professional tire dealer before deciding whether it can be repaired. It is clearly stipulated that the sidewall cannot be repaired, the hole diameter penetrated by the crown cannot be repaired when it exceeds 6mm, and it cannot be repaired when there are abnormal conditions such as damage or deformation of bead, deformation of tread, corrosion of rubber by chemicals or rolling damage of tire due to lack of air.

④ When the tire pressure does not meet the standard, the driving risk is high

When the vehicle is running, the correct air pressure meeting the requirements shall be maintained. This air pressure shall refer to the information provided by the vehicle manufacturer. The owner should check the air pressure of all tires under cooling conditions at least once a month, even including the spare tire. If the air pressure decreases too fast, find out the cause immediately. Be sure to check the air pressure before a long journey.

⑤ When the vehicle shakes, be aware of whether it is a tire problem

When the owner feels that the vehicle vibrates excessively, he should be alert to whether there is a problem with the tire, or the tire positioning is poor, or the tire wear consumption is uneven, such as the tire shoulder wear is faster than the rest of the tread, etc.

When these conditions occur in the tire, continued driving will not only damage the tire life, but also affect the vehicle handling and cause danger.

Car tires, including spare tires, must be checked regularly every month. During inspection, observe whether there are cracks or scratches on the tire surface at the same time. It's best to put on gloves and stretch out to the inside of the tire to check whether there are suspicious traces. If any suspicious point is found, please ask the car dealer for detailed inspection immediately. Don't be reluctant to throw away the defective tire. If you find that the tire surface wear is abnormal, you should think that there may be a problem with the toe adjustment of the wheel and have to repair it. In daily life, it is necessary to test the tires in the following aspects:  

① Outer edge wear

Cause: if you observe along the driving direction, there is large wear on the outer edge of the tire, which indicates that the tire is often under inflated, that is, the pressure is not enough.

Solution: check the tire pressure several times. If possible, inflate according to the "expressway" standard, that is, add 30000 PA more than the normal standard. Moreover, it is generally believed that since the tire is under inflated, it is conducive to driving in snow and sand, and it can also be so on wet ground. It should be noted that under inflated tires are very unfavorable to driving in rainy days, and the grip will be significantly weakened.

② Convex and corrugated wear

Cause: if it is found that both sides of the landing part of the tire are convex worn, and the periphery of the tire is also corrugated worn, it indicates that the shock absorber, bearing, spherical coupling and other parts of the car are seriously worn.

Solution: due to the high cost of replacing a new tire, it is recommended that you check the wear of the suspension system before replacing the tire. If it is not serious, you can choose to replace the worn parts. Otherwise, even replacing the tire will not help.

③ Uniform surface wear

Reason: it is normal for the tire to wear evenly, and each part will have corresponding performance. Once the pattern has been worn dry, it indicates that the service life of the tire is exhausted. At this time, it should be replaced. In addition, the pattern also has the effect of draining water in the road area.

Solution: never make your own tire patterns. If the wear has reached the standard depth of the tire pattern (usually 1.6 mm, 2 mm for tires with a width greater than 175 mm). Of course, the degree of wear will vary, but it should be noted that the wear difference of different tires on the same axle shall not exceed 5mm.

④ "Hidden injury" in tire

Cause: after the vehicle collides with hard objects (such as hitting the edge of the sidewalk), or after driving under the condition of flat tire, the rubber layer of the tire will have serious scratches, affecting the sealing degree.

Solution: if the wound is small, of course, it can be repaired in case of need. However, if you want to drive long distances, you must replace it immediately.

⑤ The center part is worn

Cause: if serious wear is found in the central area of the landing part of the tire, it indicates that the tire is often over inflated, which is not conducive to tire maintenance, but accelerates tire wear.

Solution: first, be sure to check whether the pressure gauge is accurate and adjust the pressure. Only when driving at high speed or under heavy load, it is necessary to inflate the tire excessively, which is not necessary under normal conditions.

⑥ Tire side crack

Cause: due to poor maintenance or driving on stony roads and construction sites, hard objects contact the tire, causing damage to the inner layer of the tire under heavy pressure.

Solution: take immediate action. If the repair fee is not too expensive, it is better to repair it, otherwise it is necessary to replace the tire. Although new technology has been applied to today's tires, they are more delicate and should be properly maintained.

(1) Tire wear

The shoulder of each Hongyu tire has a pattern of triangular mark, which is used to guide the position of tire tread wear indicator. This triangle mark can help you find a protrusion at the bottom of the groove of the tread pattern, that is, the wear mark, with a height of 1.6mm (the legal minimum groove depth). When the tire is worn to the same height as the wear mark, it means that the handling and safety of the tire can not be guaranteed and must be replaced in time.

Hongyu suggested that tire replacement should be considered before such a degree of wear is reached. When excessively worn tires are used on slippery roads, the tread pattern cannot drain the water under the tires, which is prone to sideslip and increases the risk of driving out of control.

(2) Tire damage

Hitting the shoulder, sinking into a pit or inserting nails while driving may seriously damage your tires.

The damaged tire is likely to be repaired, but only professional tire dealers are qualified to accurately judge whether the tire can be repaired or can only replace it with a new tire.

(3) Tire aging

When the tire enters the aging period after a certain service life, you should always check whether there are small fine lines (front and side), tread deformation and obvious cracks. Once found, please stop using these tires immediately and ask professionals to check and judge whether the tire can continue to be used. If not, it must be replaced immediately.

Shandong Hongyu Rubber Co., Ltd. was founded in 1995. Since its establishment, it has been committed to tire high-tech R & D and brand construction and development. It has developed more than 1000 kinds of tire specifications and become a leading enterprise of high-performance tires. The company has advanced tire production, R & D and testing equipment, professional technology and management team, and has established a perfect quality assurance system. From the beginning of the company's construction, Hongyu has always adhered to a research and development concept. We will not sacrifice the performance of tires in terms of mileage and safety in order to emphasize the fuel-saving performance of tires. Therefore, Hongyu tires are committed to highlighting its safety, durability and energy saving.

Security

At present, the vast majority of vehicles, regardless of purpose, grade and power, fall on the tire. Therefore, safety is closely related to the tire. As the only contact point between the vehicle and the ground, the tire plays a key role in driving safety. In order to improve the safety of the tire during driving, Shandong Hongyu Rubber Co., Ltd. has further improved and optimized the tire sidewall, ply, tire belt and tire tread to improve the safety performance of the tire.

durability

We all hope that the tire can have a longer service life, but the tire wear is inevitable during driving. In order to minimize the wear of tires during driving and improve the durability of tires, Shandong Hongyu Rubber Co., Ltd. has made great improvements in its tire structure and rubber performance. After many tests, it has accurately determined the best proportion of carbon black in the rubber formula, and produced tires of corresponding specifications according to different working conditions and working environment.

Energy saving

You know what? The tire consumes 6% - 10% of each tank of oil you add. Isn't that incredible? This is precisely because of the existence of rolling resistance. Reducing rolling resistance is the main way to save fuel. Shandong Hongyu Rubber Co., Ltd. integrates silicon raw material into the tire tread as a partial substitute for carbon black. Silicon helps to reduce rolling resistance without reducing tire grip (especially on wet roads) and wear resistance, so as to improve energy saving.
