What should I do if the direction deviates after the front and rear tires are replaced

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.

Hello, according to your description, if the direction of your car will deviate after the front and rear tires are replaced, then you need to do a four-wheel alignment. Generally, after the front and rear tires are replaced, you need to do four-wheel alignment, and you will not deviate if you do the four-wheel alignment.

If the direction is deviated, you can do a four-wheel alignment, and if it is a tire rotation, you can do a dynamic balance.

Hello, if the front and rear tires are crossed and crossed, they run off. It is very likely that the tire has insufficient tire pressure, so you should check the tire pressure first.

Hello As you said, if there is a problem after changing the tire, it is recommended to check whether the tire pressure is consistent and whether the tire is deformed.

Hello, the front and rear tires you said deviated after reversing, it is recommended to do a four-wheel alignment balance.

The general common sense is that the front tires are steering drive wheels, so they will be better when doing dynamic balancing, while the rear wheels will be relatively poor! After the reversal, the rear wheels need to be dynamically balanced.

Hello, if you change this tire, you have to do a four-wheel alignment, and if you don't do it, it will deviate.

If you do this, after the front and rear tires are replaced, you need to redo the four-wheel alignment.

This has to do a four-wheel alignment, such a replacement tire is easy to deviate without four-wheel alignment.

Hello, this one needs to do a four-wheel alignment, which is caused by the wrong front speed ratio caused by you replacing the tires.

Hello, do you not do dynamic balancing when the tires are rotated before and after? If it is too large, it is recommended to do a four-wheel alignment!

Check the dynamic balance of the spare tire.

Check that the tire pressure on both front wheels is the same.

Check whether the wear degree of the surface of the spare tire is smooth and new, and whether there is a tire gnawing and obvious high and low phenomenon.

For safety reasons, all tires on the car must be dynamically balanced, and spare tires must be used well, because it is possible to change to any wheel position at any time.

Four-wheel alignment is based on the vehicle's four-wheel parameters, which are adjusted to ensure good driving performance and certain reliability. The installation between the steering wheel, the steering knuckle and the front axle of the car has a certain relative position, and the installation with a certain relative position is called steering wheel alignment, also known as front wheel alignment. The front wheel alignment includes four contents: kingpin camber (angle), kingpin camber (angle), front wheel camber (angle) and front wheel toe.

This is the relative position of the two steering front wheels and the rear axle for the two rear wheels, which is called rear wheel alignment. Rear wheel alignment includes wheel camber (angle) and rear-wheel toe-in by rear. In this way, the front wheel alignment and the rear wheel alignment are collectively called four-wheel alignment.

There are many reasons for mistrackingInsufficient air pressure in the tires can cause misalignment, the degree of tread pattern wear is not the same, there is a problem with the design of the suspension system, or the suspension is injured.

Due to the different working conditions and loads of each tire, the rear wheel load of the truck is generally greater than the front wheel, and the front wheel load of the car is generally greater than the rear wheel, if the driving position is on the left side.

Normally, the speed of the car when turning left will be greater than the speed when turning to the right, resulting in the tire on the right side of the car being stressed more than the left tire when turning left, and the right edge of the right tire is most worn after the car has traveled a certain mile. On the contrary, in right-hand driving areas such as Hong Kong, the United Kingdom, and Australia, the outside edge of the left tire is more worn.

Tire rotation should adopt different rotation methods according to the different characteristics of tires:

1) Transposition of tread non-directional bias tires. Since the front wheel is worn heavier than the rear wheel when the tire is in use, the tire on the same axle can be swapped to make the left and right sides of the tire wear evenly. After a period of use, the replaced tires on the front axle can be scrapped, retreaded or used as spare tires, while new tires are installed on the front wheels.

It is more economical to do so.

2) Transposition of radial tires. Radial tires should be kept on the same side of the vehicle, i.e. in the same direction of rotation. The rotation direction of the radial tires is fixed, and if the direction of rotation is reversed, the vehicle will lose its handling stability, make the car unsmooth and vibrate.

What should I do if I keep mistracking when driving after changing new tires? Do you want to do wheel alignment?

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.

1.Tire loss.

The imbalance of tire pressure on both sides of the vehicle will directly lead to the deviation of the vehicle! The principle is very simple, the tire pressure on both sides is unbalanced, on a flat road, the left and right are high and low, and the vehicle will naturally deviate to the side of the gas loss.

Solution: It is recommended to check whether the tire pressure on both sides is normal, if there is a loss of air, then carry out air filling, if there is still deviation, then continue to look down.

2.Wheel alignment.

For vehicles that have been driven for a period of time, changes in wheel alignment data can also lead to mistracking. Especially for vehicles that often walk on potholes and on and off the road, the parameters of four-wheel alignment are more likely to change.

Solution: Find a time to go to the 4S store to do a four-wheel alignment, the probability of deviation caused by this reason is quite large.

3.The wheelbase on the left and right sides is inconsistent.

Wheelbase is the distance between the two perpendiculars that pass through the center of two adjacent wheels on the same side of the vehicle and are perpendicular to the longitudinal plane of symmetry of the vehicle. To put it simply, it is the distance from the center of the front axle to the center of the rear axle of the car. As shown in Fig-2, a is the wheelbase of the car.

If the body is deformed greatly, and it is not corrected in time, or it does not meet the technical requirements after correction, it will lead to the inconsistency of the left and right wheelbases, and the load-bearing body of the car is more prominent. When a car is moving, it is deflected towards the side with a shorter wheelbase.

Solution: First of all, check the wheelbase on both sides with a four-wheel aligner, if the wheelbase difference does not meet the technical requirements, the body corrector can be used to restore the deformation. When making a preliminary judgment, you can also use a meter ruler to measure at the center of the wheel.

4.Chassis problems.

Mistracking can also be caused by changes in the main components of the chassis, which can be due to wear and tear caused by daily driving, or due to frame deformation caused by accidents. If there is a change in components such as the lower swing arm or the gap is too large, adjusting or replacing the parts can be solved; If it is caused by the deformation of the car body and the damage to the frame caused by the accident, it is more serious, and it is necessary to replace parts in a large area or even to correct the frame before it can be fully recovered.

The new car has changed the tires a little to the left deviation, considering that it is a new tire, the main reasons for the deviation are the lack of tire pressure and the balance and positioning of the tires are not done, may sometimes go to the side of the road or quickly pass through the pit when the front wheel data changes lead to eating tires, replace the tires and then do a 4-wheel alignment.

There are mainly the following reasons for the deviation of the car's direction:

Insufficient air pressure in the tires will cause them to deviate;

The degree of wear of the tread pattern is not the same, and it will deviate;

If there is a problem with the design of the suspension system, it will deviate;

Suspension injuries, deformations, displacements, and ......deviation will occur, 5

The quality of the steering system will also affect the straight line of the car.

Caused by brakes, the difference in the size of the gap between the left and right brakes and the shoe pads will also cause brake deviation.

The normal road surface is sloping, high in the middle and low on both sides, so in China, the car will generally deviate to the right on the road.

First, check the tire pressure, if it is normal, and then check whether the front wheel toe is normal.

Go to the 4S shop to do four-wheel alignment, or tire pressure detection, which specifies that there is a skimm, and the tire pressure is unstable.

The dynamic balance of the new tires must have been done, and if it is still off, do a four-wheel alignment!

What should I do if I keep mistracking when driving after changing new tires? Do you want to do wheel alignment?

I've encountered it, and I tried to switch the left and right wheels with a slight deviation.

One. The middle pattern of the tire is smoothed, which means that the tire pressure is too high. This can be the case with particularly wide tires.

If the tire has been hit with nitrogen, it is generally rarely ground in the middle, but if the air has been played, the water removal of the compressor is not good, and there is too much moisture in the air, and it is easy to have intermediate grinding.

Two. One side is smoothed, the other side is fine. Typical eccentric grinding.

In this case, there is a problem with the four-wheel alignment data, mainly because of the toe-in problem, and it should be noted that it is not only the front wheel, but also the toe-in. Both the front and rear wheels have toe-in.

When the tires are eccentric, you can ventilate or redo the wheel alignment according to the situation.

There are many reasons for mistracking: insufficient tire pressure can cause mistracking, varying degrees of tread wear can cause mistracking, suspension design problems or suspension injuries can cause mistracking. Due to the different working conditions and loads of each tire, the load of the rear wheel of the truck is generally greater than that of the front wheel, and the load of the front wheel of the car is generally greater than that of the rear wheel.

In general, the speed of the left turn will be greater than the speed of the right turn, resulting in a greater pressure on the right tire than on the left side. After a certain mileage, the right edge of the right tire wears the most. Conversely, in right-hand drive areas such as Hong Kong, the United Kingdom, and Australia, the outer edge of the left tire is more worn.

Tire transposition should be based on the different characteristics of the tire to adopt different transposition methods: first, the tread pattern non-directional bias tire transposition. When using tires, the wear of the front wheels is heavier than that of the rear wheels, so replacing the tires on the same axle can evenly wear the left and right sides of the tires.

After a period of use, the replaced tires on the front axle can be scrapped, retreaded or used as spare tires, and the new tires can be installed on the front wheels. It's more economical and reasonable. Second, the transposition of radial tires.

Radial tires should be used on the same side of the vehicle, i.e. in the same direction of rotation. The direction of rotation of radial tires is fixed. If the steering is reversed, the vehicle will lose handling stability, allowing the vehicle to ride smoothly and vibrate.
