How to identify the Accord s tires to be replaced?

In general, tires have wear limit markings.

When the tire pattern is too shallow, in addition to poor drainage, the heat of the tire crown can not be discharged in time, so that the tire temperature rises, and during emergency braking, it is easy to knock off the tire crown glue and cause a puncture. In addition, the pattern is too shallow, and it is especially easy to be punctured by sharp and hard objects, causing accidents.

So, to what extent should the pattern be changed? In general, each tyre has a small "A" symbol on its sidewall every 60°, for a total of 6 small "A" (Michelin tyres are its little snowman logo). In the part of the crown opposite the small "A", the limit of the residual depth of wear of the pattern is engraved under the pattern.

When the tread wears up to this residual depth limit, the tire should be replaced and should not be used again. Experiments have proved that the residual depth of the tread pattern of the tire can not be lower than generally, otherwise, both the driving force and braking performance of the tire will be greatly reduced, and when encountering the waterway, there will be the phenomenon of "water sliding" mentioned above.

On waterlogged roads, as the speed of the vehicle increases, the tires begin to take water, and the ground contact area of the tires becomes significantly smaller. In addition, the amount of rainfall also has a significant effect on the coefficient of friction. On asphalt pavement, the coefficient of friction of the tires drops sharply after the rain begins.

As the mud or dust is washed away by the rain, the coefficient of friction of the tire increases. After the rain stopped, the friction coefficient of the tires gradually returned to normal values as the road surface continued to dry.

In addition, if you are using a snow tire, there is a limit to the residual depth of wear on the tire. A typical snow tire has its maximum wear limit when the pattern is worn by more than half. That is to say, when the pattern of the snow tire is worn by more than half, the pattern of the tire loses the role of the snow tire and can no longer be used as a snow tire.

Many drivers do not pay attention to the deep groove of the tire, and some of the patterns are still in use when they are ground to the ply. Some people spend money on food and never care, but when it is time to change the tire, they swallow it, you must know that the phrase "spend money to buy lessons" does not apply here, because the lessons on the car are all lessons of blood, and they cannot afford to buy them. In short, don't underestimate the pattern on the tire, it is a very important part of the tire, face it and treat it as required, you can avoid a lot of accidents that should not happen.

Here's how you can tell if a tire needs to be replaced

Point 1: If the tire is aging (for example, there are countless small cracks in the tread groove or sidewall that are about to hurt the carcass), the tire needs to be replaced in time, regardless of how long the tire has been used and how much it has been worn.

The second point: if the depth of the groove left in the tire pattern is at or below millimeters (there is an indicator mark indicating this depth in the groove of the longitudinal straight bar of the tire tread), the tire must be replaced, because the drainage capacity of the tire has been greatly reduced, and the vehicle will be more dangerous to drive in wetlands.

In addition, damaged tires should also be measured whether they need to be replaced, for example, although the tires can still be driven in an inflated state after being crushed by air failure, because the internal structure of the tires may have been damaged, it is recommended to replace them with new tires in time. In particular, it should be reminded that bulging tires should not be used any longer.

Whether it is recommended to replace the tires is recommended to refer to the above, which is not necessarily related to the number of kilometers and time used by the tires.

In addition to normal tire wear, if the tire is found to be bulging or damaged, the tire should also be replaced in time.

There is a safety line in the groove of a qualified car tire, and it is generally necessary to replace it when it is worn to the safety line.

Look at the wear indication sign of the tire pattern.

The 2018 Honda Accord uses two types of tires: 225 50R17 and 235 45R18.

The original tire brands used in 225 50R17 are: Bridgestone, Michelin.

The brand of 235 45R18 original tires for general use is: Yokohama.

Most of the original factories use tire brands Michelin or Dunlop, but also use Yokohama and Bridgestone. The tire size is divided into 225, 50R, 45R18 models according to different configurations. Tire Replacement Tutorial:

Park the vehicle on a level pavement and loosen the screws diagonally. The jack is aligned with the support point at the bottom of the car, and then the vehicle is slowly raised to remove the tires.

There are a lot of Continental brands, Michelin etc.

There are three brands of 10th generation Accord tires, such as Bridgestone, Michelin and Hankook tires, and different models use different tires.

The specifications of the 10th generation Accord tires are 225 50 R17 94V, and the original tire brand is Michelin Primacy 3. The inside of the wheel is covered with shock-absorbing glue, and the opening on the side of the tire is connected through the opening on the spoke, which reduces the wind noise during driving to a certain extent.

The Accord uses tires with a size of 225U002F50R17. Its manufacturer is Michelin. It has high quietness and comfort, and the shape is also very attractive.

In order to realize a comfortable and enjoyable mobile society, Guangqi Honda has made safety the biggest theme of its manufacturing based on the basic philosophy of "respecting people's spirit". Honda's unique "accident prevention safety technology" and "passenger safety technology" have adopted Japan's first anti-lock braking system, the world's first automotive steering operating system, Japan's first SRS airbag system, the world's first FF traction control system, and the world's first "shake driving detection function" for mass production. 2.

Compared with the previous generation of the Accord, the 10th generation Accord looks very young, because the younger is already an unstoppable trend, this generation of Accord also conforms to the public opinion, compared with the past, it is much younger, using Honda's latest turbo engine.

The use time of tires is affected by many external factors, such as climate, road conditions, driving habits, maintenance conditions, etc., under the conditions of good car condition, good driving habits, and good road conditions (the road surface is not very rough, there are not many curves), the general tires can be used for 3 to 5 years.

You can check the wear of the tire tread and stop using it when the tire tread is worn to the limit mark, i.e. the tread depth is less than millimeters.

In addition, tires are rubber products, and there will be aging after a long time, and you can also judge from the surface that there will be many fine cracks on the surface of aging tires and sidewalls.

If you find that the cracks are dense or have a certain depth, it proves that the aging has been more serious and needs to be replaced in time.

1. Check the tire pressure regularly.

Tire pressure is an important factor affecting the life of tires, do not be too high or too low, and inflate according to the tire pressure indicated by the vehicle. Try to keep the tire pressure low in the summer; In the cold winter, try to ensure that the tires of the car are more inflated than in summer, because the tires are easy to expand and contract.

Second, the wear and tear of the tires are often checked by searching.

Sometimes individual vehicles will "eat tires", which is necessary to check the tires frequently, especially the inside, to see if there is abnormal wear, mainly to observe whether the depth of the tread on both sides of the tire is consistent.

3. Remove small stones and other foreign objects in the tires in time.

Foreign objects in the tire pattern are potentially dangerous, and they are prone to splattering out of the car while driving. Therefore, if you find small stones, you should use a key to pick them out and try to ensure that the tires are clean.

4. Rotate tires on time.

The front wheel of the car is a steering wheel, the wear is relatively large, generally in order to reduce the wear of the money wheel, after the first warranty of the vehicle, every 5000 kilometers or so for a four-wheel replacement, preferably diagonal replacement.

5. Regular four-wheel alignment.

When the vehicle deviates or other abnormal steering, it is necessary to give the tires in time.

6. Repair the tire in time.

If the vehicle has nails, even if there is no air leak, replace the spare tire as soon as possible, and then replace the nail tire.

Check the wear and tear of the tires during the fixed delay period, and replenish the air pressure in time.

2.Clean your tires frequently to prevent dirt build-up and keep your tire surfaces clean.

3.Regularly check the balance of the tires to ensure that the vehicle is stable. Paidan Bureau.

4.Check the tread depth of your tires regularly to make sure they are in safe condition.

5.Check the expiration date of tires regularly, and replace tires that exceed the expiration date of dust in time.
