What are the main aspects to look for when inspecting car tires?

Check the tire wear, if the tire is worn too much, the braking effect will be reduced (and the road surface Demi friction force is reduced) when the braking distance is lengthened, and it is easy to burst when driving at high speed, this kind of tire should be replaced in time. Insufficient tire pressure or uneven pressure on the left and right sides of the tire can also cause jet lag in braking effect, difficult steering or heavy steering, and also reduce the service life of the tire. The above consequences are more serious when the load capacity is large.

Therefore, when the tire pressure is insufficient, it should be inflated in time. The left and right wheels should be tires of the same specification and model, and the degree of wear should be the same. Otherwise, the steering braking performance of the vehicle will be affected.

<> it is best to look at the air pressure of the four tires before getting on the car every time, if you find that there are different tires from other tires, it is likely to be a flat air, and the tire pressure of the spare tire must be checked before running a long distance! It's a good idea to have a tire pressure gauge on board. The tire pressure of the average car is between bar, summer, winter+.

If you find that there is a leak and replace the spare tire to repair the tire, do not force it to repair the tire, so that the tire or even the wheel hub will be scrapped! First, check the tire date, preferably not more than 4 years. Second, check if the tires are bulging.

Third, check if the tires have reached the alarm line. Fourth, steering wheel shake can also identify tire deformation or need to do tire dynamic balancing.

The second is tire wear, we say that when the tire is abnormally worn, we should analyze the reason, whether it is a friction that is not paid attention to when parking, or a problem with positioning, if this abnormal wear is left alone, it will cause the stability of the vehicle to decrease, poor handling; Tire pressure must be checked at any time, this is the same as bicycle tires, car tire pressure should be controlled between, if the air pressure is too high, the comfort will be reduced, the tire will be worn more severely, just look at the grip will be weakened, oversteering, especially in the summer driving the car for a long time will have the risk of puncture.

1 bulging: when the car drives through the potholes, obstacles and the curb at speed, the tire part will be seriously deformed under the huge impact force, and the internal pressure increases instantaneously, and the direct consequence of this is to cause the tire to bulge. Tires that have already swollen must be replaced immediately, otherwise there is a risk of a puncture.

2 Pattern: Generally speaking, the normal use of the family car can change the tire every 60,000 kilometers or two years, but the tire with serious wear should be replaced early. Nowadays, repair shops have pattern wear scales, and car owners can buy one to check the pattern wear of their tires at any time.

In addition, the increase in tread cracks is also a sign of serious tire aging, usually the owner can properly spray some tire protective wax, and try to press the corrosive liquid when driving.

3 Air pressure: For front-wheel drive vehicles, the front wheels sometimes look a little deflated because the engine, gearbox and other important driving components are pressed on the front. If the visual inspection is accurate, be sure to use a special tire pressure gauge to measure whether the tire pressure is normal.

4 Pebbles: Some car owners often hear that their cars will make a sound when driving, but there is no fault when driving, then you should check that there are pebbles stuck in the tire pattern. In fact, you only need to take the time to dig out these stone particles in the tread pattern with a key.

Spare tire: If you want the spare tire to play a real emergency role, you should also pay attention to its maintenance. First of all, check the spare tire air pressure frequently; Secondly, the spare tire should pay attention to the anti-oil corrosion of the tire.

When inspecting car tires, it is mainly to observe three aspects, first of all, the air pressure of car tires, to observe whether there is air leakage and lack of air. The second point is to observe the degree of wear and tear of the car's tires. The third point is to check whether the balance of the four wheels of the car's tires is balanced.

When checking the tires, the main thing is to check the degree of wear on the surface, as well as their air pressure value, because if the air pressure is too low, you will be afraid that there will be no gas when driving, and you will not be able to continue running, but if the air pressure is too high, there may be a puncture.

Inspections General inspection items include:

Outer edge size, tensile strength, elongation at break, permanent tear deformation, abrasion (Akron), hardness, durability, high-speed performance, appearance quality, lug rubber flexural resistance test, sidewall rubber ozone aging test, tensile strength of the traveler, air tightness, tubeless tire detachment resistance, adhesive strength, sinking amount, sinking rate, grounding coefficient, static load performance, absolute value of tensile strength change rate after aging.

Tire is one of the important parts of the car, which is in direct contact with the road surface, and the car suspension works together to alleviate the impact of the car when driving, and ensure that the car has good ride comfort and driving smoothness; Ensure that the wheels and the road surface have good adhesion, and improve the traction, braking and passability of the car; Bearing the weight of the car, the important role played by tires in the car is becoming more and more important.

Answer: Check the pattern, check the tire pressure, wheel alignment, dynamic balance, etc.: This is still very important to ensure safety.

It is a free public welfare event. Just ask a Bridgestone Wings store near you. Follow-up:

The activity will also be carried out in large supermarkets or around the community, which is really convenient. Follow-up answer: Anyway, it's free, it's convenient to go and see it in the past, the master of Chezhiyi is still very professional!

Expand your knowledge: choose a qualified four-wheel alignment maintenance point, four-wheel alignment precautions:

When doing four-wheel alignment for vehicles, you should choose which regular, large-scale four-wheel alignment equipment repair shops, and pay attention to check whether the positioning instruments of the repair shop are advanced and qualified, and the data is accurate. Otherwise, your vehicle is normal, and the repair shop will "make a problem" with your vehicle in order to make a profit, which is the unspoken rule of the repair shop, so pay special attention to it. When performing tire four-wheel alignment, you should carefully observe whether the maintenance person's operation is standardized, so as not to hurt your vehicle.

Don't choose a repair shop that is too cheap to do wheel alignment, otherwise there will be some undesirable consequences.

Before driving, check tire pressure, wear, and the sidewall for scratches or bulges. The main impacts are:

1.Insufficient tire pressure can lead to increased fuel consumption and poor handling.

2.Severe tire wear can lead to failures such as insufficient grip, deviation from direction, tail flicking, etc.

3.Scratches and bumps on the tire walls can greatly increase the probability of a tire burst while the vehicle is in motion.

There are several reasons for insufficient tire pressure and severe wall wear.

Generally, car tires should be tested for tire pressure, and if you look at the wear of the tires, if the wear is relatively large, then it is recommended to replace them.

One: the grounding coefficient, which can know the condition of the tire more accurately. Second: static load performance, if not checked, it is easy to cause damage to the car. Three: It is also necessary to check the absolute value of the tensile strength change rate of the tire after aging.

What is the right thing to do when it comes to inspecting car tires? Let's take a look at this problem**, I hope these contents can help friends in need.

Because the tire pressure of each car is different, the first thing to know about the applicable tire pressure of your car is to know. For the determination of the range of tire pressure, you can consult the 4S worker, you can consult the manufacturer, you can check the instructions for use, and you can query the logo on the car. The way to estimate the tire pressure, you can squat on the ground to check the number of tire teeth that the tire hits the ground, 4 5 teeth are all normal, and you can estimate the tire pressure according to this specification every day.

Tire pressure can be measured according to the instrument, and the tire pressure test equipment can be purchased, but the transposition that has been plugged into the valve cannot be applied. Many cars are equipped with tire pressure monitoring equipment, pay attention to the inquiry, usually put the time on the usual observation, check the tire, and be sure to dismantle and replace it on time when you get to the police line. Tires in the application of 3 years or more than 30,000 kilometers need to pay attention to whether the tires must be replaced, before running long distances or high speeds, must go to the technical professional maintenance area to inspect it.

Generally speaking, the tire pressure standard of automobiles is in the middle of 230-250kpa. The actual car is normal, and the tire pressure also needs to be based on the recommended value of the car manufacturer. Generally, you can find the recommended value of the automobile manufacturer on the side of the car owner's manual, the car door (around the B-pillar) in the car cab, the drawer cabinet next to the driver's seat, and the oil cap door.

It will be a complete indication of the actual application of the tyre's pressure. The tire pressure specification is related to the type of tire and the car, and the weight, relative height and tire size of the car are different for different car series, and the tire pressure required is also different. The basic tire pressure is 240kpa-250kpa; The tire pressure of the reinforced tires is 280kpa-290kpa.

In addition, the tire pressure of cool tires is not the same as that of hot tires, and the pressure of hot tires is about 20kpa higher than that of cold tires. The recommended value of the automobile manufacturer is the tire pressure value of the cold tire, and the tire pressure in the case of a cold car is up and down 230kpa-250kpa, and the actual tire pressure of each car is used as the standard. 4. The tire pressure is also very disturbed by seasonal reasons.

In summer, the weather is high, and the tires are easy to get hot during the driving process, and if the tire pressure is high, it is very easy to cause tire puncture, and the tire pressure should be lower; The tire pressure in winter is a little higher than in summer, and due to heat shrinkage and thermal expansion, the tire pressure of the car in winter is generally more suitable in the middle of 250kpa-280kpa.

It can be determined by some tire pressure detectors, or through the internal dashboard, so that the pressure problem can be better judged.

When checking the tires, you must check the tightness of the rivets of the noisy car tires, and secondly, you also need to check the tires to a certain extent, because this macro will affect the normal driving, and if there is a problem, it will affect the traffic accident. Envy.

You can remove this tire and put it in the water to see if it bubbles, if it doesn't, it means it's very good.

Generally speaking, tires for family cars can be replaced every 60,000 kilometers or two years during normal use, but tires with severe tread wear should be replaced in advance. At present, all fast repair workshops have a pattern wear gauge. Car owners can buy one at any time to test the tread wear of the tire.

In addition, the increase in tread width is also a sign of severe aging. You can properly spray some tire protection wax under normal circumstances. Also, don't try to squeeze corrosive liquids while driving.

loch.Have you ever had a problem with your car? If yes, how long has it been?

For tires that have been repaired for a long time, even if temporary use is not a problem, in addition, if there are more than three punctures in the same tire, we recommend replacing them as soon as possible.

Some car owners often hear their car "popping" while driving, but this car is flawless. At this time, you have to check if there are any small stones in the tire pattern, in fact, as long as you usually take the time to dig these small stones in the tread pattern with the key, not only can the brake handle of the tire be more stable, but also avoid tire noise.

How to check a tire drum pack. When a car passes through mines, obstacles, and street teeth at high speeds, the tires undergo strong deformation under the force of a huge impact, and the internal pressure increases immediately. As a direct consequence, the sidewall cord breaks, causing deformation.

In addition, under the same impact force as a low-deflation tire, it is more likely to cause lateral deformation than a high-deflation tire. The tires, air pressure, must be replaced immediately. Most family cars now use tubeless radial tires.

For front drive, the front wheels sometimes look a bit flat because the engine, gearbox, and other important components are pressed forward, but visual inspection is wrong. We need to use a special tire pressure indicator to measure it. In general, the air pressure between the front wheels may be lower in the summer.

When choosing tires, we must first ensure that the tires can not be overloaded, for the same specification of tires may have different load capacity, it should be noted when selecting, one is that the same specification of tires has different structural layers, so the load capacity is also different, to choose carefully.

I think the inspection of tires is very necessary, tires are a very important part, if there is a problem with the tires, there are great safety hazards, accidents are likely to occur, so you should develop this good habit in normal times, check the tires regularly.

It should be checked every two months, and the tires must be replaced in time, and the correct tire pressure must be maintained at the right time, and then be sure to go to a professional 4S shop or repair shop to replace the inspection.

I usually check the surface to see how well the tires are sticky, and I always check before every drive.

Clean the foreign matter in the tire tread groove, regularly check the tread wear and finally check whether the tire pressure is normal. It is recommended to check whether the rubber thorns on the tires are worn when picking up the car. If you can't see the thorns, say.

Ming definitely exceeded 100 km. Don't trust the odometer.

<> need to change your tires in the following cases. Serious aging, observe the pattern of the tire and the lines on the sidewall, if cracks are common, it means that the tire has been seriously aged. Although the mileage is not long or the use time is not long,..

However, it still needs to be replaced in time. Otherwise, aging tires are prone to the danger of punctures due to the increase in temperature due to the weakening of the sidewall strength during high-speed driving.

Wear is severe, and each tire tread groove has a wear limit marking, which is about 2mm thick (the exact value is. Professional tire shops recommend that the tire thickness is worn to the distance from the limit sign with two limit signs. height (immediate, should be checked frequently, conditional is recommended to replace.)

Tire bulging is also a very common thing, especially for owners of potholes, obstacles and speed bumps that often drive fast, local tires are prone to serious deformation after a huge impact force, and the internal pressure increases instantly, resulting in bulging.

Tires with bulges need to be replaced immediately, otherwise there will be a risk of a puncture, so this problem must be checked and replaced as soon as there is a need. The importance of tread for tires is self-evident. Generally speaking, the normal use of the family car can be replaced every 60,000 kilometers or two years, depending on the wear and tear of the pattern, if the pattern is seriously worn, it needs to be replaced in advance

In fact, the naked eye can roughly see the pattern wear, if you are not at ease, you can buy a pattern wear scale, at any time to detect the tire pattern wear. In addition, the appearance of cracks in tires is also an important sign of aging, if you find that there are cracks in tires, in order to ensure safety, it is best to replace tires in time.
