Tire maintenance tips and use car tire maintenance common sense

Every 10,000 kilometers to change the tire position, so that tire fatigue uniformity, to avoid bias grinding; extend tire life.

1. Tire replacement "benefit a lot"

Every 10,000 kilometers to change the tire position, so that tire fatigue uniformity, to avoid bias grinding; extend tire life.

2. Driving habits of the "four notes"

Prevent fast start, emergency braking or sharp turns; prevent hitting the road tartar; prevent riding on the road tartar when stopping; prevent fast through the unpaved roads and bad roads.

3. Four-wheel alignment "need to remember"

Advocate every two thousand kilometers to test; due to shorten the four-wheel alignment of the main parameters of the changes in the car tires related to abnormal wear; car overloaded or bad road, please go to a special store to check; to prevent the car tires due to changes in the main parameters of the four-wheel alignment of the abnormal wear.

4. Tire pressure "needs to be carefully checked".

At least once a month to check the air pressure of all tires, including spare tires; long-distance driving before the tire pressure; if the tire compression is too short too fast, please go to the local store to find the cause.

5. Don't forget to dynamically balance the tires.

When the car body shakes or the steering wheel shakes during driving, please go to the authorized store to check; after the car goes through the bad road, please go to the authorized store to check; when replacing the tires or changing the position of the tires, the dynamic balance of the tires must be checked.

6. Tire life is "very important".

If the depth of tire grooves is close to 1.6 mm, it is recommended to replace the tires; if the tires have aging cracks, it is recommended to replace the tires.

Misconceptions about tire maintenance

Misconception 1: Wash the car as soon as you return from your trip.

Some friends are quite "diligent". As soon as the car stops at home, you need to clean up the dust and mud stuck during the trip, which is not good for the tires. Because the tires just stopped or hot, if immediately rinsed with cold water, it is easier to harden and aging.

Myth 2: tires can be used for ten years.

Most of the family car, under comprehensive road conditions, the use of tires and replacement time can refer to two norms: one is the use of time shall not exceed 5 years; or comprehensive road conditions driving distance not more than 60,000 kilometers. If friends often drive on unpaved roads, it is necessary to replace tires earlier according to tire wear.

Myth 3: After changing the tires, you can go on the road.

Some of my friends are pretty frugal and can save on a lot of post tire change items. I think there are some items that must be done after changing tires, such as dynamic balancing and four-wheel alignment.

Dynamic balancing is to adjust the weight balance of the tire. Most of them just need to "move" the tires, which is basically what they do. Because the wheel is composed of tires and hubs, it is impossible to distribute the mass of each part completely evenly after replacing the tires. When the wheel rotates at a high speed, it becomes "dynamically unbalanced" through developmental changes, causing the car to tremble and the steering wheel to shake.

In order to prevent this phenomenon, it is necessary to use a balancing machine to test the balance of the tire rim in a moving state after changing the tire, and to ensure the balance of each edge of the wheel alignment by adding counterweights to the imbalance points.

Four-wheel alignment is to tell the geometric angles of the tires, steering, suspension and other components to ensure that the tires are tightly bonded to the ground. After changing the tires to do four-wheel alignment, to avoid inaccurate positioning to affect the excessive wear of tires, related to the controllability of the car and the coefficient of safety.

Myth 4: Tire pressure energy is low in summer when the temperature rises to avoid a flat tire.

As the driving distance increases, the tire temperature will rise. At this time, the tire pressure is higher than the tire pressure in the cold tire state. Many friends think that this will increase the risk of a flat tire. I think that after driving for a period of time, the tire temperature will stabilize and the tire pressure will not continue to rise. If you deflate and depressurize the tire because you are worried about the risk of a blowout due to increased tire pressure, it will lead to increased tire carcass deformation during driving, but

Some friends feel that the spare tire is not on the road, so they don't need to change it, and they can save some money. I think tires are rubber products, so there will be rubber aging. The shelf life of rubber is mostly 4-5 years. After the shelf life, the rubber will age faster and the performance will decline rapidly. So when you replace all tires at 5 years, it's best to replace the spare tire along with it.

Myth 6: pet urine will corrode tires.

Nowadays, many people have pets, from time to time there will be a small dog in the tire next to the urine, which makes a lot of friends are very troubled, worried that the rubber of the tire will be corroded. I think this worry is completely unnecessary. The urine of cats and dogs and other pets will not react with the rubber, and the aging effect is minimal. Car wheel surface layer basically do anti-corrosion treatment, basically are resistant to strong acids and alkalis, let alone a pet's urine.

Myth 7:To change tires, just replace the damaged ones.

If the size, structure and wear state of the four tires are not consistent, it will affect the handling and stability of the car. So it's best to use basically the same brand for all four tires, with similar specifications, so as to ensure the best performance of the car.

When a tire wears out and needs to be replaced, it is best to replace all four tires at the same time if one tire is in doubt. Even if it is not possible to replace all of them at once due to certain conditions, at least two tires on the same axle must be replaced at the same time. Every 10,000 kilometers, the tires can be adjusted to avoid irregular wear and tear, so the life of the tires will be extended.

Myth 8: The higher the tire pressure, the better, can save fuel.

When the car tire pressure is insufficient, the tire sidewalls will appear over lifting phenomenon, which will easily lead to uneven tire wear and increased fuel consumption. Some friends think they can adjust the tire pressure a little higher to solve the problem and save fuel. However, if the tire is over-inflated, it will be more susceptible to external impacts and uneven wear, and as the tire temperature rises, the tire pressure rises further, and there will be a risk of blowout.

Myth 9: Ordinary cars can also be used with anti-blast tires.

Some friends say, since the consequences of a tire blowout is so serious, directly replace the tires with blowout-proof tires is a big mistake.

The scientific name of the anti-blast tires is "air leakage protection tires", optimized from the sidewalls of ordinary tires. Compared with the same period last year, the installation of explosion-proof tires in the car are basically in the chassis, suspension, rim hump and other places to carry out a special design. After changing the ordinary car explosion-proof tires, it will affect the comfort and handling.

Myth 10: Brush tire oil after car wash can maintain tires.

Many car cleaning store in the car wash after the car tires will be free to brush a layer of tire oil, claiming that the tires dust and shine, but also maintain the tires. Some friends are very confused, tricked. Rubber is soluble in grease solvents, most of the tire oil used for car cleaning is of poor quality, it will corrode the tires and wheels, increasing tire wear and affecting the life of the tires.
