The displacement of large automobile tires has nothing to do with the axle tube

This is normal now, the grip of the new tires is relatively large, the resistance will naturally be greater, and the relative vehicle will be more stable.

General precautions for replacing tires: only one tire is replaced, generally placed on the rear wheel, the front wheel is the brake wheel, and the height of the left and right tires should be kept as consistent as possible, including wear and tear.

Principle of Tire Replacement].

1.Same specifications Different specifications of tires have different outer diameters and cross-sectional widths after inflation, and the load distribution is different when installed on the same axle.

2.The same structure The carcass structure of the radial tire and the bias tire is different, and its cushioning performance and circumferential deformation are different. If the two tires are mixed on the same axle, the load will be different and the wear will be inconsistent.

3.The material is the same The material mainly refers to the material of the carcass cord. For example, there are great differences in carcass thickness, cord strength, and heat dissipation performance between all-steel radial tires and fiber radial tires, and they are mixed together to affect the use effect.

4.The same level is the load level of the tire, and the corresponding air pressure standard is determined, the tires with different load capacities are mixed together, the inflation pressure is inconsistent, and the deformation of the tire is also different.

5.The same pattern of the tires is different, not only the wear is different, but also the adhesion to the ground is not the same, the left and right tire patterns of the car are inconsistent, which will affect the smoothness of the car, and there will be unilateral and tail flicking phenomena during emergency braking.

6.The same brand is different from the manufacturer, and the tire hub size, tread width, pattern shape, and cord material have certain differences. Tires of different brands mixed together will affect the use effect.

7.Same air pressure The air pressure is determined by the layer, tires with the same layer should keep the air pressure consistent, inconsistent air pressure will cause different tire deformation.

8.Equipping tires with the same load capacity with the same load capacity can extend the service life of the tire.

The tires have nothing to do with the brake pads, are the tires replaced the original car tires? If so, the new tires have better grip than the previous ones, and it's normal to have a little more resistance.

Do your tires have direction? If there is, it is installed in the wrong direction, and the resistance of the tire in the wrong direction will be greater.

Changing tires should be made with radial tires, which have less resistance than bias tires. Fuel consumption will also be lower. Secondly, if you are not professional in the process of changing tires, screwing the tire nut may cause the brake hub to shift or the brake clearance to deform, so there will be a feeling of great resistance.

You should go to the 4S store to recalibrate.

There are many factors that lead to vehicle deviation, such as poor four-wheel alignment such as vehicle beam angle and camber angle, road arch, wind direction, etc., and tires-related factors such as eccentric wear, uneven air pressure, taper effect, etc.

It will have to do with tires.

Solution: 1. Check whether the tire tread is eccentric, if so, please go to a professional tire shop to check and adjust the wheel alignment, and at the same time transpose the tire;

2. Check whether the tire pressure on both sides is consistent, and adjust to the same standard if not;

3. Confirm the four-wheel alignment status;

4. Transposition the tires of the whole car and reconfirm;

The uneven sidewall of the tire belongs to two different conditions. One is dented, which is made up of the tire carcass

The joint of the cord is caused by the fact that the joint is two layers of cord, and the other positions are one layer of cord, so the strength of the joint position is actually higher than that of other positions. In the early stage of tire use, the tire will expand slightly under the action of air pressure, and the expansion of the joint position is relatively small, and it looks like it is concave. The second case is the bulge, which is caused by the joint of the inner liner or the sidewall rubber, due to the relatively thick position of the joint, the appearance is somewhat convex in the inflated state.

Judging from the above causes of unevenness, whether it is a depression or a bulge, it has no impact on the performance and safety performance of the tire, and because the process of tire production process determines that this unevenness is fundamentally unavoidable, it is something that every tire has, but the degree of external uplift is slightly different. So please feel free to continue using it and do not need to replace it.

There are many reasons for vehicle mistracking, such as poor dynamic balance, abnormal tire wear, tire installation, air pressure, vehicle positioning or damage to parts and components.

It is recommended that you visit a professional retail store and have the staff check it out to determine the specific cause.

Doing a four-wheel alignment may have something to do with the tires, but the key is the four-wheel alignment.

Vehicle mistracking.

One is that the four-wheel alignment of the car is not done well, or the run-in period needs to be adjusted, and the second is that the wheel is worn differently caused by different capacity, especially the front wheel has a nail, and the spare tire is changed, and the wear is different, resulting in deviation.

Third, sometimes the inconsistent air pressure of the front tire also has an effect.

Fourth, the road surface conditions lead to running all over, and the road surface is inclined or rough and smooth on the other side, and there is also a certain degree of deviation.

It's related, you go and do a four-wheel alignment.

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.

Tire pressure problems.

Inaccurate wheel alignment.

Problems with the braking system.

Chassis failure.

Connected by the wheel core, the half shaft is the outer spline, the wheel core is the inner spline, and the suspension system is the support for the wheels, not the half shaft.

The axle and the wheel are connected by splines, and there is a universal joint at both ends of the half shaft, which is connected to the spline, one end is connected to the wheel axle, and the other end is connected to the gearbox output end, and the two half shafts drive the two wheels. Because of the universal joints and splines, the wheels can be turned at an angle without affecting the transmission of half-shaft power.

Automobile axles (also known as axles) are connected to the frame (or load-bearing body) by a suspension, and wheels are mounted at both ends. Purpose: It is the suspension, not the axle, that transmits the force and moment between the frame and the axle (wheels).

The role of the axle is to bear the load of the car and maintain the normal driving of the car on the road.

Front-drive cars have gearboxes connected by an inner cage to the axle to the outer cage and the outer cage to the wheels.

I'll give you a ** and I'll understand!

The transmission output power is driven by a driveshaft that drives the half-shaft, which is connected to the wheels.

It is best to use the same tires for all 4 wheels, and if the conditions are limited, it is also necessary to ensure that the tires of the same axle are exactly the same.

Tires are responsible for long-term, over-frequency contact between the vehicle and the road. It is responsible for important responsibilities such as load-bearing, braking, driving safety, and driving comfort. However, when the vehicle is driving normally, the area where the tires are really in contact with the ground is actually not large.

This small contact area, which requires so much important work to be completed, has a lot to do with the tire pattern.

The tire pattern plays a role in increasing the friction between the tire and the ground, reducing tire noise, enhancing comfort, dissipating heat and draining the tire, and improving the vehicle's handling performance.

Tires with different patterns show different properties, generally speaking, tire patterns are various longitudinal, transverse, and oblique grooves on the tire tread. Don't look at these horizontal and vertical patterns are very messy, in fact, they have a very clear division of labor.

The different patterns make the car wear and tear different in driving, which first affects the tire itself, and will also cause the inconsistent braking resistance of the car, resulting in the anti-slip and other systems always maintaining a working state, which has great damage to the car itself. When the car needs to brake sharply at high speed, the different tires may cause uneven force, which may cause traffic accidents.

If conditions permit, it is best to use tires of the same size, structure, manufacturer, and pattern (load index, speed level) for all four tires, plus proper alignment, to help maintain the wear rate of the tires, so that the performance of all tires is consistent. If for some reason, only the brand of the front and rear tires is different, it is okay to have different patterns, but the same axle should be equipped with tires of the same specification, structure, manufacturer, and pattern (load index, speed level).

It is okay for the front and rear patterns of car tires to be different.

Tires of the same specification, structure, manufacturer and pattern should be assembled on the same axle. (Load index, speed level is the same) as long as ensure that the coaxial tires are the same, the difference between the front and rear tires will not affect the normal driving (of course, the difference brand, the grip of the tread, drainage and other characteristics will be different, if conditions permit, it is recommended that the front and rear 4 tires are the same).

However, strictly speaking, it is better to use tires with the same front and rear treads.

It's okay, as long as the two front wheels and the two rear wheels have the same patternThat is, tires of the same specification (including speed level and load index), brand and pattern should be equipped on the same axle.

Reasons why tires with the same axle are consistent:

The consistency of the front and rear wheels can ensure that the friction of the front and rear wheels is the same, and if the friction is the same, there will be no brake deviation.

Inconsistent direction and inconsistent patterns will affect braking performance, tire rolling resistance and tire grip, such as vehicle deviation during sudden braking, or tire grip at the critical point of loss of control.

Knowledge Expansion:

The role of tire pattern: the tire pattern is not only for decoration and good look-looking, the tire pattern is also related to whether the performance of the tire can be fully played, such as: traction, braking, cornering, drainage, silence and so on.

It doesn't matter, the front two are the same, the back two are the same, it's no problem, as long as the front two are not the same, the front tires are easy to deviate if the two patterns are not the same, you have no problem changing like this.

No problem, Michelin tires are much better than Kumho, 91W is not as good as 91V when you are driving too high, but now there are not many V, but it doesn't matter. It's the same.

Yes, in fact, the general use of the tire pattern is not high, only requires enough friction. In fact, Michelin tires are still very good.

Yes, the pattern may vary depending on the brand, but the model is the same.

No problem, as long as you keep the two front wheels and the two rear wheels consistent, safety can be guaranteed.

Because the consistency of your front and rear wheels can ensure that the friction of the front and rear wheels is the same, and if the friction is the same, there will be no brake deviation, so no problem.

The front wheels you use are Michelin, which is already better in terms of braking effect, and if you change them later, you will change the Michelin ones, and the new ones will be installed in the front, and the old ones will be switched to the back, because the braking in the front is much larger than in the rear (7; 3) So the previous ones are best to keep the new reliable security.

When purchasing tyres, it is necessary to ensure that the tyres must be the same as the other tyre with the same axle, that is, the same axle should be equipped with tyres of the same specification (including speed class and load index), brand and tread.

In the case of replacing only two tyres, it is recommended that the new tyres be fitted on the rear axle of the vehicle.

Reason: If you put a tire with more wear on the rear axle of the vehicle, because the weak drainage capacity of the tire will greatly increase the risk of oversteer in rainy days, and the risk of vehicle flicking may occur.

If two tires with different speed classes are installed on the same vehicle, regardless of the drive axle, install the tires with the higher speed class on the rear axle to prevent potential vehicle oversteer.

The speed level of your new tyres is higher than that of your old tyres (V: 240 km h, w: 270 km h), so from this point of view you should also install your two new tyres on the rear axle.
