LaVida rear wheel tires eat tires?
LaVida 17 automatic comfort version has a serious rear tire puncture. How to get it out? Did you do a four-wheel alignment? The main reason why tires eat tires is that the center of gravity of the vehicle is unstable. Generally, cars are front engines, with occupants in front and front wheels as driving wheels. In general, the front wheel wear is more serious than the rear wheel; Some models have rear engines, or other factors, such as bulletproof body, which causes the center of gravity to shift and the rear wheel of the tire is seriously worn; However, when designing vehicles, designers will try to avoid center deviation; Even if there is a prejudice against eating tires, the situation will not be too serious; Finally, the four-wheel alignment of the tire is not good, and the tire is eccentric, resulting in abnormal wear. That is, abnormal fetal eating. It is recommended to do the next four-wheel alignment. Four-wheel alignment includes front wheel alignment and rear wheel alignment. Front wheel alignment is to check the installation position between the steering wheel, steering knuckle and front axle of the vehicle, including caster angle, camber angle and toe-in of the front wheel. The rear wheel positioning is relatively simple, mainly the installation position between the rear wheel and the rear axle. Rear wheel alignment includes camber and toe-in one by one. Front wheel alignment and rear wheel alignment are generally called four-wheel alignment. If the car tires are eaten seriously, you can see that they are off-center and badly worn. It is suggested to do dynamic balance and four-wheel alignment, which will generally solve the problem. I suggest you check whether the four-wheel alignment and dynamic balance data are normal. (1) In general, the vehicle should be re-inspected once every 8000 to 10000 kilometers, so it should be inspected at least twice a year. (2) Check the tire wear at least once a month. For example, if the tire wears unevenly, one shoulder of the tire wears faster than the rest of the tread. Or, if you find that the vehicle is shaking excessively or out of control, your vehicle may be poorly positioned or unbalanced. These conditions will not only shorten the life of tires, but also affect the handling of vehicles, which may be dangerous. If you find irregular wear or vehicle shaking or deviation, please check the wheel alignment and balance immediately. (3) In addition, it is recommended to do four-wheel alignment when replacing new tires. (4) Every time the tire is transposed, four-wheel alignment inspection can also be carried out. Generally, the phenomenon of tire eating can be repaired by four-wheel alignment. Roadside tire shop 50 yuan, 4S shop may cost several hundred yuan. Personally, I suggest 4S processing. After all, they have official data and may do better. Tire transposition: 1. Full-size spare tire 5000km tire is transposed once, and the balance should be moved every time. Five-wheel counter-clockwise circulation transposition method can be used. That is, when the spare tire is transposed for the first time, the original right front tire is used as the spare tire, with the right rear in front of the left, left front to left rear, left rear to right rear, and left rear to right rear. The second time is the same. The same is true after running 40 thousand kilometers. It is advisable to use a spare tire, and others need to be rotated. 2. For riders with small spare tires but not full size, cross transposition method can be used. They also need to change this balance. They can be interchanged at a distance of 5000- 10000 km, that is, right front and left rear, left front and right rear, directly next time, that is, right front and right rear, left front and left rear, and then right front and left rear are interchanged next time. In the last period, the tire wear will be different because of the different stress points at each position. So each tire will be subjected to different stress environment. Only in this way can the tire wear be consistent and reach the maximum service life) 1. Simply put, eating tires means that the abnormal accelerated wear on the inner or outer side of one or more tires is particularly fast than that of some parts of other tires, which can be obvious when checking tires. 2. What caused it? Generally speaking, there are several reasons. A. The four tires are not in the horizontal and vertical straight lines required by the standard due to the inaccurate positioning of the four wheels, so the two wheels on the same side will eat the tires when driving, or the front wheel or rear wheel mainly does not go in a straight line, and the vehicle corrects itself, resulting in abnormal friction between a certain part of the tire and the ground, which increases accelerated wear. I'm a little unclear about what I said, but I don't know how to express it. Anyway, imagine that the four wheels of a car should be on four fixed points of a rectangle. If they don't run like that, they will compete and cause tire wear. B. Inappropriate toe-in adjustment can also cause fetal eating. What is toe-in? That is, the front wheel leans slightly inward at an angle, similar to the inner figure of eight. This is the best angle for high-speed and stable driving. All cars have their own toe angle. Improper adjustment of this angle will also cause fetal eating. C. Failure of steering gear will also cause tire gnawing deviation. D. uneven deformation of the girder can also cause tire eating. For example, some accident cars eat tires because the beam is deformed. E. the air pressure difference between the tires is too large. Most people will eat tires of different specifications. The reason is the same, that is, if you don't work in a smooth environment, you will eat tires because you can't eat anything else. Hahahaha, the main reasons are almost these. 3. How to solve the girder deformation, there is no other way except to correct it. It is not difficult to do it yourself. Most tires can be corrected by adjusting toe-in and four-wheel alignment. I suggest you do a four-wheel cross transposition first. When doing four-wheel cross transposition, the four-wheel tires must be dynamically balanced. If there is still the phenomenon of eating fetus after transposition, it is necessary to do four-wheel positioning. Four-wheel alignment refers to the installation of chassis objects such as automobile wheels, shock absorbers and steering rods in a certain relative position, which is called four-wheel alignment. The distance and angle between these relative positions are the parameters of four-wheel positioning, and we do four-wheel positioning around these parameters. By adjusting these parameters, the car can reach the best state. In fact, four-wheel alignment is a maintenance method, not a maintenance project. If there is no obvious problem with the vehicle running, four-wheel alignment is unnecessary. In other words, four-wheel alignment is only needed if there is something wrong with the car, so it doesn't need to be done regularly like maintenance, it depends on the situation. @20 19
