What are the common problems with car tires?

Tire pressure, most family cars now use tubeless radial tires. In the case of front-drive vehicles, the front wheels sometimes look a bit flat due to the engine, transmission, and other important drive components pressing against the front, but visual inspection is inaccurate. We had to use a special tire pressure gauge to measure it.

In general, the air pressure of the front wheels is between Pa to Pa.

Bulging tires and even lack of glue and air leaks. It may be because the carcass rope is overstretched and breaks. When the vehicle is driving, the tire shoulder or the tire edge close to the tire shoulder is severely squeezed between the rim flange and the colliding object due to the strong impact of external foreign objects such as pits, curbs, large stones, etc.

If the tire is bulging, it is prone to the risk of puncture, please replace the tire as soon as possible.

Tire dentation, which is caused by the tire joint part, is a relatively solid part of the tire carcass and will not affect the safe use of the tire. Usually, the depression caused by the carcass cord corresponds to the position on both sides of the tire, in addition to the normal sidewall straight bar depression, the depression in the rest of the situation should attract enough attention from the owner. These can be tire failures caused by a cut tire sidewall, a tire sidewall impact breakage, or rubber degradation.

Tire cracks, there are many different patterns on the surface of the tire. The function of the tread pattern is to ensure good adhesion, drain water from underneath the tire and maintain vehicle control. The more tread patterns, the less likely it is to "drift" when driving on wet roads.

On the surface, this situation looks like nothing is wrong and is very similar to the previous one, but the difference is that in the former case, it is scratched by a foreign object, and the quality of the tire itself is not a problem. However, it can be difficult to tell if the crack is an external cause or an internal problem with the tire, so it's best to inspect the tire carefully. In most cases, a tire replacement is required.

For example, the grip of the tire is not particularly strong, and sometimes there will be bulging, the tread wear on the tire is particularly serious, and the aging situation is particularly serious, including tire slippage and tire denting.

The tires are broken, the tires are broken, worn out, there is too much gas, the model and the car do not match, and the tires have a lot of problems.

The problem of tire pressure, the problem of tire wear, the problem of tire repair, the tire needs to be replaced in different weather, and the quality of the tire.

Common problems in car tires are air leakage and puncture of tires.

Tires are the main part of the car, and the working conditions are very harsh. In addition to supporting the weight of the vehicle, it also transmits driving torque and braking force to mitigate the impact of the vehicle. If the use and maintenance are not good, it will accelerate wear and tear and even scrap, affecting driving safety.

So in the use of tires, what are the common faults?

1.Bulging. Bulge is a common tire injury caused by the impact of the car on the shoulder or sidewall of the tire. The bulge will affect the performance of the tire, and in serious cases, it may even lead to a puncture, please go to the GAC Toyota sales store in time to replace the new tire.

2.Wear and tear of the tires.

The main reason is that the tire pressure is too high, which will lead to serious tire deformation, and the contact area with the ground will also become the crown part, resulting in excessive wear, not only that, but also affect the comfort of the car (increasing the tire pressure appropriately can reduce rolling resistance, but it is recommended to use standard tire pressure).

3.The left and right front shoulder shoulders are wavy and worn.

The inside of the left rear wheel and the outside of the right rear wheel are heavily worn. The main reason is that the axles corresponding to the front and rear wheels are not parallel, and the right wheelbase is larger than the left wheelbase, which exceeds the standard. This is also why when doing four-wheel alignment, it is common to see a master holding a square ruler to measure the length of the wheels on both sides.

The specific positioning parameters are related to the tilt of the wheels back and vice versa.

4.Sharp objects such as iron nails suddenly pierced.

Almost all cars are fitted with tubeless radial tires that do not burst immediately even if they are suddenly punctured by a sharp object such as a nail. On the contrary, when a tire with an inner tube is suddenly punctured by a sharp object such as a nail, air will flow through the gap between the inner tube and the inside of the tire, and from the gap between the valve and the steel rim, and the air inside the tire will drop sharply immediately. Tubeless tires don't blow out immediately because the air will only slowly expel through the punctured hole.

5.Tires with bald areata wear.

Severe wear and tear of alopecia areata in some parts of the tire may be due to a problem with the dynamic balance of the wheels. When the wheels are unbalanced, the wheels are running at high speeds, and some parts of the tires will be subjected to greater force, which will increase wear and tear, and cause the steering wheel to shake (which occurs at high speeds or at certain speeds).

Bad habits in the process of car driving can easily lead to the wear and tear of car tires, and car tires are an important part of the car, which is related to the performance and driving safety of the car. Special attention should be paid during the use of the car to prevent abnormal damage to the tires and prevent early wear of the tires. The load of the tire is certain, and the overload operation should be avoided as much as possible, and the serious overload will lead to a tire puncture of the car.

For example, there is a flat tire, or there is not enough tire pressure, or there is a bulging tire, and there may be serious wear of the tire, or the tire is deformed.

These faults are, tire cracks, tire punctures, tire cracks, tire leaks, inner tube damage, and wheel hub damage, which are relatively common faults.

Abnormal tire pressure, serious wear of the tread of the tire, problems with the hub of the tire, ** tire, and leakage of the tire, these are relatively common.

For example, there is an environment where the tire is flat, or the tire pressure is not enough, or the tire is bulging, and there may be an environment with significant wear in the middle of the tire, or an environment in which the tire is deformed.

<><What you don't know about tires in cars

Remember what was the first step in taking the Driver's License Test Subject 3?

Maybe you forgot about your friends, right? Go around the car to check for foreign objects and check for abnormal phenomena such as flat tires!

For novices, what is the abnormal situation of the tire, and how should it be dealt with if there is an abnormal situation?

Today I will talk about passenger car tires, which are the problems and solutions that often occur in our common family car tires!

1.Worn on one shoulder

One side of the tire wears out quickly, but the other side is normal?

There are several reasons for this:

The four-wheel alignment of the car is poorly corrected, to put it bluntly, the tires on both sides are not parallel, resulting in more tires landing on one side and less on one side when driving; It is also possible that there is a problem with the suspension system, which requires the driver to drive the vehicle to the garage for correction.

Another is when the tire is installed, there is no dynamic balance test, the tire itself causes unilateral wear, if there is no problem with the four-wheel alignment, the unilateral wear tire will be replaced as soon as possible, so as to avoid safety problems.

2.Intermediate wear

The first of these conditions is that the inflation pressure is too high, resulting in a long time in the middle of the tire touching the ground and severe wear.

The rims and tires do not match, the tires are upgraded but the rims that are not replaced are removed, and the small feet wear big shoes.

3.Worn shoulders

Corresponding to intermediate wear, this situation is generally caused by insufficient air pressure.

In addition, it is often too sharp to turn, resulting in serious wear on both sides of the tire.

It is also possible that the rims and tires do not match, and the big feet wear small shoes.

4.Sidewall bulge

There are many reasons for this situation: before installation, it is necessary to check whether the tire leaves the factory, and do not replace the tire regardless of asking, and the installer is not responsible, resulting in such a quality tire installation, causing potential safety hazards.

If manufacturing causes are ruled out, the tire suffers from a side impact; This problem can be caused by punctured tire tread and tire mouth damage; The sidewall of the tire is a cord that will bulge out on the sidewall if the crown and mouth of the tire are hit or damaged.

The tire is the only part of the car that touches the ground, pay attention to the tire and take responsibility for your own life safety.

The aspect ratio is the ratio of the height from the rim to the tread to the maximum width measured by the section of the tire, expressed as a percentage, i.e. height as a percentage of width. Take the 205 60R15 size tire as an example, its maximum cross-section width is 205 mm, the tire has an inner diameter of 15 inches, and the aspect ratio is 60.

Generally speaking, at present, domestic cars use more tires with small width, small inner diameter and high aspect ratio. Tires with a high aspect ratio are relatively comfortable due to their long sidewall and strong cushioning capacity, but they have a poor feel to the road surface and have weak lateral resistance when cornering. On the other hand, tires with a low aspect ratio and a large inner diameter have a wide tread due to a short sidewall.

Therefore, the ground contact area is large, the pressure that the tire can withstand is also large, the response to the road surface is very sensitive, and the lateral resistance when turning is strong, so that the handling of the vehicle is greatly enhanced.

Generally speaking, the tires that leave the factory are the best specifications selected by the manufacturer after repeated testing. If there is a car owner who wants to change the tire size, it must be carried out under the guidance of professionals, and cannot be done arbitrarily, because this involves many problems, and a slight negligence may cause harm to driving safety. In addition, the low flat tire will appear more "delicate", and should be more careful and cared for during use.

I don't plagiarize or quote.,If it's not clear, you can continue to ask.,I'm not searching for information blindly.。

1.The layman's explanation of the flat ratio is: tire height and tire width.

I drew the picture myself. The height is the part drawn in the picture, and the width is how wide the wheel is, which is easier to understand. If you ask whether the inner diameter or the outer diameter is the outer diameter, both height and width refer to the outer diameter.

2.The flatness rate of sports cars (performance cars) is generally below 40, such as 30, 35. Professional off-road vehicles are generally above 60, such as 60, 65, and 55. MPVs don't have a particularly noticeable range, but they are generally above 50.

3.Question 2 and Question 3 are related.

The flattening rate is small, and the relative tire width and short (thin):

When it is wide, the contact area with the ground is large, and the friction is large, and the handling is good, but it costs fuel.

If it is short, it can withstand lateral stresses more and at the same time has a small buffer margin for vertical stresses. The corresponding effect is better handling when cornering, and more bumpy roads when the road is not usual.

The flattening rate is large, and the relative tire is narrow and high (thick):

The effect is the opposite of the above.

If you want to get a flat tire, just do it.

If the wound on the countertop is not big, go to repair the tire, and if it is too big, replace it, safety first.

But remember, whether it's a tire repair or a tire change, you have to redo the balance after that.

It shouldn't have any effect. Probably will. A little bit safer.

For example, when driving at high speeds, the tires are punctured. The inner tube also acts as a cushion. The gas will slowly drain away.

Instead of being deflated in an instant.

The most mentally retarded method inherits the shortcomings that the inner tube will be bitten by the outer tire, and abandons the advantage that the vacuum tire is not afraid of punctures (the nail is broken and the inner tube is finished, because the vacuum tire is no longer the main body of negative pressure, and the air valve of the inner tube is not sealed) Moyou often make smart and stupid mistakes.

This doesn't work because tubeless rims are different from tubeless ones.

Can you still put it on with an inner tube? He's talking about truck tires, but they're not called vacuum tires.

Add an inner tube to it, and a vacuum tire.

I don't think it makes a difference, I know a lot of Gala tubes, so economical, just do the dynamic balance, how much does it cost to change a tube, how much does it cost to add an inner tube, as long as the tires don't bulge the tires like the Gala inner tubes, run at high speeds.
