How to check general tires? How to check car tires?

The tire pressure should be checked at room temperature every month, and if it is lower than the normal standard, the tire pressure should be replenished in time. The air pressure should not be too high or too low, otherwise it will affect the safety of driving. Check the cracks of the tires, and replace the tires in time when there are potential safety hazards.

When choosing tires, they should be of the same type.

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.

1. Wear limit, this is the most basic inspection item, in the groove of the tire pattern, there are some small protrusions in the design, called the "wear limit mark", commonly known as the "safety line", when the tread is worn to the limit mark, the tire should be replaced.

2. Check whether the tire pattern is mixed with a lot of stones or other foreign objects.

3. Pay attention to whether there is a bulge on the side of the tire, if there is, it means that the cord layer or steel wire inside the tire has been broken, which will be the weak point of the whole tire, and it is also the hidden danger of puncture in the future. If you find a bulge, be sure to replace the tires as soon as possible, and be sure not to run at high speeds.

4. Check the tire pressure.

The methods of vehicle tire inspection are: 1. The tire pressure should be within the calibrated air pressure range of the vehicle; 2. The degree of wear of the tire pattern should not exceed the preset wear mark at the bottom of the tire pattern; 3. There should be no stones and metal foreign bodies in the groove of the tire tread; 4. The tire sidewall should not have any bulge, which represents the fracture of the nylon cord on the side, and there will be a potential danger of puncture if you continue to drive. The maintenance method of tires is:

1. Clean the stones in the tire gaps regularly; 2. Reduce tire exposure; 3. Detect the tire pressure in time; 4. Pay attention to the maintenance of suspension; 5. Regularly check the front wheel alignment; 6. Pay attention to the driving mode, choose the road surface to drive in the car, avoid objects that can puncture and scratch the tires, and avoid the corrosion of tires by chemical residues.

Before driving, you must check the tire pressure, wear, and whether the tire wall is scratched or bulging. The main impacts are:

1. Insufficient tire pressure will lead to an increase in fuel consumption and poor handling performance when the vehicle is driving.

2. Serious tire wear will lead to insufficient grip, direction deviation, tail flicking and other failures when the vehicle is driving.

3. Scratches and bulges on the tire wall will greatly increase the probability of a puncture when the vehicle is driving.

There are several causes of insufficient tire pressure, serious wear, and tire wall scratches.

The tire pressure should be within the calibrated air pressure range of the vehicle; 2. The degree of wear of the tire pattern should not exceed the preset wear mark at the bottom of the tire pattern; 3. There should be no stones and metal foreign bodies in the groove of the tire tread;

The simplest and roughest way to step on it with your feet to see if there is any air leakage or puncture; The main screen of the car has a tire pressure monitoring function, which will automatically alarm if a nail is pierced; Go to the 4S shop, and people will use professional equipment to monitor your whole tire, and it is best to maintain it at the right time.

1) Check the tire inflation pressure.

Ensuring that the tire pressure is normal is the first condition for the operation of the tire. Therefore, the tire pressure should be checked frequently with a Pirmin tire pressure gauge. If the tire pressure is too high, the rigidity of the tire will also increase, which will reduce the contact area of the tire, which is easy to cause early wear of the crown, thereby reducing the service life.

The low air pressure of the tire reduces the rigidity of the tire, the radial deformation of the tire increases, the uneven distribution of the ground contact area leads to the overheating of the tire, the adhesion of the rubber decreases at high temperature, and the cord is loose, which is easy to cause early wear of the tire tread, thereby reducing the service life. The difference between the normal inflation pressure of the tire and the standard value should be within 5%. (2) Check the side of the tire.

Inspect the crown surface on the side of the tire for scratches, cracks, and bulges. When the car passes through potholes, obstacles, and curbs at high speed, the local tires will be seriously deformed under the huge impact force, and the internal pressure will increase instantaneously, which is the direct result of tire bulging or abrasion. Tires with bulges or severe scratches must be replaced immediately, otherwise there is a risk of being punctured.

If there is an abnormality, it should be repaired or replaced.

3) Check for tire wear marks.

When tire wear marks appear, the tire should be replaced. The tread of small car tires is generally embedded with 8 wear marks and a width of millimeters; The sidewall of the tire in the corresponding position is marked with "S", "A" or "TW1". When the tire tread depth is less than millimeters, the wear indicator strap will be exposed.

If the wear indicator strip is visible from more than two adjacent grooves, the tire should be replaced in a timely manner. Automotive Repair Technology Network.

For vehicles that are frequently driven on highways, tires should be replaced when the tread depth of the tires is less than millimeters. When the tread depth is less than 4mm, there will be no effect of driving in the snow, and it should be replaced when driving in winter.

4) Check the tire tread.

The tire tread is partially worn and the tire cord layer may not be exposed. There must be no more than 2 cracks and scars on the tread and sidewall of the tire. 5 cm long, deep enough to expose the tire cord layer.

If the exposed cords and bumps on the tire have hard cuts or cracks, it means that the tire is a safety hazard and has low safety and should be replaced. (5) Whether there are stones or nails on the tread.

The car makes a sound when it is moving, but there is no hassle while driving. At this time, you should check the tire tread for pebbles getting stuck. Car owners can usually solve the problem by using the key to pump out these small stones in the empty tread pattern, or the repair master at the workshop will be happy to help.

6) Check for abnormal wear of tire tread.

The wear and tear of the tire tread can reflect the technical condition of the vehicle's use and steering system. Not described in detail here, the steps to move: Tire tread abnormal wear check. For details, please refer to spare tire inspection analysis.

Everyone knows the role of the spare tire, if the spare tire plays a real emergency role, then it is necessary to pay attention to the maintenance of the spare tire.

The first shed in the world, to check the spare tire pressure frequently; h tt ps://2019

The method of vehicle tire inspection is as follows:1. The tire pressure should be within the nominal pressure range of the vehicle; 2.

The degree of wear of the tire pattern should not exceed the preset wear mark at the bottom of the tire pattern; 3.There should be no stones and metal foreign objects in the groove of the tire tread pattern; 4.There should be no bulge on the sidewall of the tire, which means that the nylon rope on the side is broken, and there will be a hidden danger of puncture if you continue to drive.

The maintenance method of tires is as follows:1. Clean the crevices of the tires regularly; 2.

reduce tire exposure; 3.Timely detection of wheel or tire pressure; 4.Pay attention to the maintenance of the suspension; 5.

Check the front wheel alignment regularly; 6.Note that the driving mode is not available. When driving, choose the road surface and avoid objects that can puncture and scratch the tires, so as to avoid chemicals splashing on the tires and corroding.

Routine inspection items for tires include: check whether the tires have cracks, cuts, punctures or abnormal wear, once the above phenomena occur, they must be stopped and repaired or replaced by professionals. Tires with abnormal wear will.

It leads to a decrease in performance, so it is necessary to regularly check the groove depth of the tire tread pattern to ensure that its depth is greater than millimeters, otherwise new tires should be replaced in time. In addition, pay attention to whether there is irregular wear on the surface of the tire, in order to prevent.

Uneven tire wear, abnormal vibration and noise generation, proper tire rotation should be carried out.

Hopefully so, thank you.

Tire routine testing includes tire embossing pattern and underwire tire age.

Hope mine can help you.
