Why did the four tires deviate after cross rotation

As for the direction of the tire pattern, there are also some tires that need to consider the direction of the tread, which is generally indicated on the side of the tire. If your problem is not a tire pressure problem, then it is a problem with the car's four-wheel alignment toe-in.

Two tires are 1400 yuan, you want to change Michelin... Buy two tires by yourself, and come back to find a tire shop to do dynamic balance installation, which is generally 15-20 yuan per manual fee. Under normal circumstances, you can buy a relatively good brand model for about 1200, and you can get 1000 if you want to be cheaper. Tires are related to life, in case the front wheel of running at high speed has a puncture... Life is worrying... In addition, deviation may be the cause of the tire, or it may be a problem with the four-wheel alignment, you can check it on the machine when you change the tire... If you feel the need to make a position, you can generally get 100 yuan.

It must have deviated, because the tread wear of the tires was not the same before, and it was good to drive for a while.

Hello! The front wheel pattern is best consistent, so that the driving resistance is the same, the rear tire wear and the front tire is not the same, due to the characteristics of China's highway pavement, both sides are low, the middle is high, the left and right tire wear is not the same, it is recommended that you carefully check the tire, tread, tire pressure, new and old degree, after that, there is the phenomenon of deviation, go to the regular repair shop to check the four-wheel alignment, front wheel toe-in... FYI:

If you've done a four-wheel shift, the first thing you need to do is make sure the tire pressure is the same. In addition, it is necessary to determine whether the tire wears the same amount, if the difference is too large, the friction with the ground will be different, and there will also be mistracking. If all of this is fine, it is recommended that you do a four-wheel alignment.

If the tire is not separated from the wheel, it is not necessary to do dynamic balancing if it is directly replaced as a whole.

There are many reasons why the steering wheel of the car cannot automatically return to the right, including damage to the car steering machine, wrong toe value, damage to the pendulum, etc., which are analyzed below.

1. Damage to the steering gear of the car:

When the steering mechanism of the car is damaged, the car will have symptoms such as difficulty in steering or the direction cannot automatically return to normal. In this case, the gap of the steering machine should be readjusted, and lubricated with lubricating oil, if the car steering wheel still cannot be corrected, it should be checked by a professional in a repair shop or 4S shop.

2. The toe-in value is incorrect

If the car does not do four-wheel alignment after replacing the tires, the toe-in value of the car tires is wrong, the tires on both sides will not reach the parallel state, and the car will not automatically return to the right due to resistance when steering. In this case, the vehicle should be re-aligned and the toe value adjusted.

3. Damage to the pendulum

If the pendulum of the car is damaged, it will aggravate the wear and tear on the inside of the vehicle's tires and affect the automatic centering function of the steering wheel. In this case, replace it with a new pendulum glue.

Things to note about car steering machines:

1. When the car is parked, the steering wheel should be corrected, otherwise it will cause resistance to the steering machine, which will affect the life of the steering machine for a long time.

2. After the car replaces the tires, do the four-wheel alignment in time and check the steering machine.

3. Lubricate the parts of the steering machine on time.

What's going on with the steering wheel not right.

1. The steering wheel is not correct after the vehicle is used for a period of time, which has a certain relationship with the tire pressure, tire wear, wear and tear of various parts of the chassis, and four-wheel alignment. If the tread pattern of the two front tires is not worn consistently, it will also cause the vehicle to deviate.

2. If there is no problem with the tire, it is recommended to go to the 4S shop to check the use of various parts of the chassis, the value of the four-wheel alignment will also lead to the problem of improper steering wheel after using it for a period of time, and it is also possible that the cross tie rod is offset to one side and causes the steering wheel to be wrong.

The steering wheel of the car needs to be adjusted in time, otherwise the potential safety hazards are great when driving, and it is very easy to have some collisions.

The difference between a misaligned steering wheel and a mistracking:

Deviation does not necessarily mean that the steering wheel is not right, and the steering wheel is not necessarily wrong, and the two can also coexist, both deviation and steering wheel error. I have encountered someone who said that the steering wheel is not correct as deviation, because after he hit the steering wheel horizontally, the car will run to the side, and he thinks that it is misaligned, but in fact, it is just that the steering wheel is not right.

Therefore, if you want to know whether your car is off, then find a relatively straight and flat road with few vehicles to try, it must be a flat road, potholes are not allowed, because the wheels will change direction when they press over potholes and bulges, and some roads will also have errors in the middle high and low in order to drain water.

Car tires can be said to be the "shoes" of the car, but at the same time tires are also consumables. Due to driving on different roads, the four wheels have different points of action, and the four tires of the car will have different degrees of wear. The purpose of tire rotation is to bring the four tires close to each other in terms of wear.

However, some car owners finally found the phenomenon of deviation after doing four rotations and dynamic balancing, but the original car was normal and did not deviate. What's going on?

1.Tire wear.

In fact, most of this situation is caused by the wear and tear of the tires themselves. When the tires are in the original position of the car, the left and right wheels experience varying degrees of wear, i.e., the wear on the left and right sides is inconsistent. While they are in the rear wheel before the wheel reverses, the slight difference does not feel abnormal, and after the wheel reverses, when they reach the front wheel, a slight deviation is felt.

Of course, some new cars may run 10,000 to 20,000 kilometers, and there are deviations if they don't reverse the tires. After doing the four-wheel alignment, I found that the data was normal, but in fact, it was a problem with the tires themselves.

2.Drive the road.

It may also be related to the road being driven. At present, the main and secondary roads in most cities are designed to be high in the middle and low on both sides, which is more conducive to drainage, and cars will have a tendency to tilt to the right when driving. If the difference in tire oil between the two sides is added together, the driver will clearly feel the signs of mistracking.

In fact, in this case, you just need to swap the positions of the left and right front wheels.

Of course, it also includes the deviation of the new car, and the four-wheel alignment data is normal. It's all reversed left and right, and most of the cars can return to normal. Unless the tire wear is very inconsistent, it will not be offset to the other side.

If the left and right wheels are reversed, isn't the order of the four turns wrong? That's right, because of bias, this method is also a last resort. After all, it is especially difficult to drive when you deviate.

However, although the order is not right, the impact is not great, because the front wheel still turns to the rear wheel, and the rear wheel turns to the front wheel, but the left and right changes have no effect on the overall wear rate of the tire. If you pay special attention, you can also swap left and right after driving thousands of kilometers. After a certain distance of wear and tear, you will not run away.

3.Tire pressures are different.

Different tire pressures can also cause the car to deviate. Because the tire pressure is not equal, the size of the tire will become different, so it is inevitable that the tire will run off when it rolls. Some cars show signs of mistracking when the tire pressure difference is or or will return to normal when the left and right tire pressures are equal.

However, some cars do not deviate when the tire pressure difference is OR or , which is slightly different for different cars.

Summary. There are two situations in which the tires are replaced, the first is that the wear of the tread on the car tires should be in a very shallow state, and there is no big problem in replacing a tire. Second, if the tread of the car tire is badly worn, and the tire has run tens of thousands of kilometers, there will be a problem with one of the tires.

At this time, only one tire is replaced, which has a great impact on the driving safety of the car, and is likely to cause the vehicle to deviate or even lose control. Because the tires are heavily worn, the new tires have more friction than the old tires, and the grip will also be great. But the old tires have weak grip.

If you only change one tire, the car will deviate due to different grip. At the same time, the vehicle will have the phenomenon of high and low, easy to bump during driving, or when the speed is relatively fast, it is impossible to better control the vehicle. In this case, try replacing a pair of tires.

However, during the tire replacement period, it is necessary to pay attention to ensure that the tire pattern, brand, structure, and specifications on the same axle are the same, so as to ensure the normal driving of the vehicle.

Hello, I bought a new car that is only 10 months old, and there is a tire on the rear wheel that has a deep cut, can I change a tire? Is there an impact? Or do you want to change the pair?

How many kilometers ran.

16000 thousand km.

My suggestion is to replace the back pair, if the wear is too large to replace a car will definitely deviate, and the four-wheel alignment will not have much effect.

It's just that I don't know to ask you, that is, the New Year ran a thousand kilometers of wear and tear before the silver, there was a tire injured, and I just want to change one, Qin regrets the old and afraid that one is not good, and the run is unbalanced, so ask your professional personnel, give a clear answer.

Cart. My suggestion is to change it to two.

In this general situation, I can only say that you can change two, you can also choose to change one, but there will be a lot of problems, I need to give you a choice.

If you change 2, put 2 new ones in front and 2 in the front.

Are you a front-wheel drive vehicle?

Mercedes-Benz C260 should be rear-wheel drive.

Then the new tires are still placed in the back, and the old tires are in the front.

If it is a car that comes to drive, the front wheels will wear out badly, so most people are to change the front wheel tires first, in fact, this is not correct, if you want to change, four at the same time, and then put the rear wheels in the garage temporarily, and then install them when the tires are almost worn this time.

Due to wear and tear, the rear tire can also be used at the same time as the front tire, which will also cause mistracking. Also, if you don't know if your car is an off-road vehicle, if so, there is still a problem with deviation after changing the tires correctly, consider adjusting the height balance. Of course, it is also very important for the new tires to do dynamic balancing.

According to the road surface conditions in our country, under normal circumstances, it is normal for the car to deviate slightly to the right. The reason is that the level of road construction in our country is different, and in order to prevent water on the road, both sides of the road surface are made slightly lower.

Hello! bai

Suggestions can be considered from the following aspects.

1. Tire pressure. zhi2, whether the vehicle four-wheel dao positioning data is.

Accurate. 3. The installation direction of the wheel capacity tire. Tires of the same specification, structure, manufacturer and pattern should be assembled on the same axle. (Load index, speed level is the same).

Find a place to change the tire or 4S four-wheel alignment to correct it. Generally, 4s points do not require money.

How many kilometers has the car run, 1, four-wheel alignment 2, whether the tire pressure of the two new tires is consistent.

First, check the air pressure. And when you change the new tires, do you have the store to do the tire dynamic balance for you. If you don't do it, you can go to the wheel right tire shop to sit on the tire dynamic balance.

It can solve the problem that the steering wheel shakes when walking at high speeds. If you've done the tire balancing, it's the car's problem. You can go to a tire shop with a four-wheel alignment configuration (it is not recommended to go to a 4S shop, the fee is expensive, unless you don't care about the money!).

Do a four-wheel alignment. It's about 100 pieces. It basically solves the problem you are talking about.

It may be that there is a problem with the quality of the tires or that the car needs to be aligned.

After changing the tires, you need to have four wheel alignment and dynamic balance, and you can do it.

Do a four-wheel alignment test, as well as a tire pressure test, it may be a problem with the camber angle of the front wheel or the toe value of the front wheel. In addition, there is no problem with the steering system.

Whether it is a tire change or a tire repair, you must do dynamic balance at the end.

Let's test the tire pressure first, it is estimated that it is the tire pressure problem, and the second is the dynamic balance.

Check the tire pressure, if the tire pressure is okay, do the wheel alignment.

Just do a four-wheel alignment.

It's no problem to do a four-wheel alignment.

I guess your tires aren't balanced yet.

Why not do a four-wheel alignment.

It is likely that the pressure of the new tire is not correct or the dynamic balance is not done well, check it according to the following points.

Measure the tire pressure.

From a practical point of view, the most common factor causing car deviation is the deviation caused by the different tire pressure. This is very simple, go to the maintenance agency to measure the tire pressure, to ensure that the tire pressure is consistent, you can solve the problem. Of course, in addition to tire pressure, different levels of tread wear can also cause mistracking, which is why it is necessary to change the tire position or replace the tire.

Wheel alignment. This measure is also the most common way to correct deviations. Compared with the tire pressure test, the cost of four-wheel alignment is higher, and the owner can first see the effect by balancing the tire pressure.

Check the suspension. If the four-wheel alignment does not work, the suspension of the vehicle should be considered. Generally speaking, if there is a problem with the design of a car's suspension, it is easy to deviate. In addition, in the process of use, suspension injury, deformation, displacement, etc. are prone to deviation.

Check the steering. The steering system may be worn for a long time, so that the clearance of each connecting part is too large, or the bearing and other components are loose, resulting in the car can not follow the normal trajectory, resulting in deviation.

Reminder: Replace both sides of the spring together.

It is particularly necessary to remind here that if the deviation is caused by suspension, the owner must replace the left and right sides together when replacing the spring, rather than only replacing the spring with unilateral problems, so as to ensure that there is no new deviation.
