What to pay attention to when Sega changes four tires

1. Choose the right tire specifications (should be consistent with the specifications on the original car, if you need to change the tire specifications, you must go to a professional tuning shop for tire upgrades or consult the vehicle manufacturer). 2. Ensure that the tires must be the same as another tire on the same axle, that is, the same axle should be equipped with tires of the same specification (including speed level and load index), brand, pattern (including special markings). 3. The new tire must be dynamically balanced.

Theoretically, you have to balance the tire when you remove it from the rim and put it back on, because you can't restore the position of the removed tire and the rim. 4. It is not recommended to replace only one tire. The principle of replacing a tyre is:

Coaxial tires must be of the same brand, the same pattern, the same size, the same load index, the same speed level, and the same pattern depth, which is for safe driving considerations. 5. When replacing new tires, you must replace the valve with a new one. This is because the valve is a rubber product and has the problem of aging cycle.

When a new tire is replaced, although the valve does not see the problem at the time, the valve may deteriorate prematurely during the life cycle of the new tire, causing a safety hazard.

Hello! When buying tires, you must first determine the specifications of the vehicle's original tires. Usually, the identification of car tire specifications is**r**, and the part is a number. (e.g. 205 55R16).

The specifications of the tires you buy must be consistent with the specifications of the tires assembled in the original car, and if you need to change the tire specifications, you must go to a professional tuning shop for tire upgrades, or consult the car manufacturer.

When choosing tyres, you need to consider the vehicle's performance (e.g. supercars, small and medium-sized cars), driving habits (e.g. gentle or intense driving style) and hobbies (e.g

Comfort, high tire noise requirements), driving road conditions (e.g., high-speed, gravel roads, winding roads, etc.) and climatic conditions (e.g., winter ice and snow weather), etc., and then choose the right tire for you according to the positioning of the tire product.

For example, for tires of the same Michelin brand, different patterns represent different product positioning. The patterns available for different specifications are also different.

If you are worried, it is advisable to replace the original tyres of Sega (there may be two or three brands).

Before setting up the jack to lift the vehicle, use a wrench to loosen the bolts that fix the hub one by one. And it should be noted that when the bolt is screwed, it should be operated diagonally. Slowly lift the jack and remove all the set screws when the tires are completely about 2 cm off the ground.

After removing the wheels, place the replaced tires on the bottom of the vehicle to prevent damage caused by sudden droppings of the vehicle. After installing the spare tire, make sure that the bolt holes are in the correct position.

Sega Tire Replacement StepsIn the process of daily driving of a vehicle, tires carry the full weight of the vehicle and are the most prone to wear and tear, and the condition of the tires is also directly related to the driving and safety of the vehicle. Therefore, it is inevitable to encounter problems such as tire failure, but can you replace the tire correctly? Before lifting the vehicle, it is necessary to first find the right position for the jack support, and usually the car manufacturer will make a mark on the corresponding body position to make it easy to find.

Take the Dongfeng Citroen Sega, the long-term test car of the Aika team, as an example, the corresponding positions on both sides of the body are clearly marked, which is very easy to find.

Before setting up the jack to lift the vehicle, use a wrench to loosen the bolts that fix the wheel hub one by one. Moreover, it should be noted that when the bolt is screwed, it should be operated diagonally.

Four kanji, four kanji?

Slowly lift the jack and remove the fixing bolts completely when the tire is completely about 2 cm off the ground. Remember to put the removed bolts in the chase as soon as you put them away, otherwise it will be troublesome to find one less when installing the tires. After removing the wheels, place the replaced tires on the bottom of the vehicle to prevent damage caused by sudden droppings of the vehicle.

After installing the spare tire, make sure that the bolt holes are in the correct position.

Four Chinese characters for those cars that use nuts to fix the wheels, this step is not too difficult, but for some models that use bolts to fix them, it is more difficult to find the right position, especially for female users. Therefore, after changing the spare tire, you can first use a small metal rod that plays a fixed role to find the position of the wheel installation, and then screw the bolts one by one.

Be sure to remember that the bolts should not be screwed in turn, and the order of installing the bolts should also follow the diagonal form, otherwise the bolts are prone to tension. Speaking of which, some netizens may ask: It is easy to operate diagonally for a four- or six-bolt hub, but what to do with a five-bolt hub?

Once the bolts are installed, do not rush to tighten the bolts completely, slowly lower the jack. When the tires are fully in contact with the ground, use a wrench to tighten the bolts diagonally one by one.

The final step is to pack up the faulty tires and tools that have been replaced, and complete the entire tire change process. At the same time, remember to send the faulty tire for repair in time.

Hello! Here's how you can tell if a tire needs to be replaced

Point 1: If the tire is aging (for example, there are countless small cracks in the tread groove or sidewall that are about to hurt the carcass), the tire needs to be replaced in time, regardless of how long the tire has been used and how much it has been worn.

The second point: if the depth of the groove left in the tire pattern is at or below millimeters (there is an indicator mark indicating this depth in the groove of the longitudinal straight bar of the tire tread), the tire must be replaced, because the drainage capacity of the tire has been greatly reduced, and the vehicle will be more dangerous to drive in wetlands.

For example, although the tire can still be inflated after being crushed by the lack of air, it is recommended to replace the tire with a new tire in time because the internal structure of the tire may have been damaged. In particular, it should be reminded that bulging tires should not be used any longer.

Whether it is recommended to replace the tires is recommended to refer to the above, which is not necessarily related to the number of kilometers and time used by the tires.

Tires generally need to be replaced after 4-5 years, mainly depending on the wear state.

Hello! Based on the information we have, the tire size you are using for this car is probably 205 55 R16. If you need to buy tires, according to your needs, Michelin recommends you:

Primacy 3 St Haoyue is a high-end comfort pattern. It is characterized by comfortable driving and low tire noise when driving. It is suitable for owners who pay special attention to the dry and wet braking performance of tires, and want to maintain the excellent comfort of tires while taking into account some handling.

For more information, please refer to the page.

You can also log in to search by vehicle to find out the right tires for your car.

Since the vehicle manufacturer does not notify the tire manufacturer of the selection and change of the original tire specifications, our information is not 100% complete, and even the same model may choose different specifications of tires with different years, so this information is for your reference only. The specifications of the tires you buy must be consistent with the specifications of the tires assembled in the original car, and if you need to change the tire specifications, you must go to a professional tuning shop for tire upgrades, or consult the car manufacturer.

Tire replacement is divided into time replacement and exercise replacement.

1. Time replacement: The 4S shop tells you that the tires will be replaced within 3 years, whether you run or not, which is. After the practice of n tires, it was found that the tires are OK within 5 years, during this period of 5 years to 7 years, some cars did not drive much, the tires were seriously cracked due to lack of water (that is, there were small cracks on the sidewall of the tires), and the crack depth reached 2mm, which means that the tires should be replaced.

2. Exercise replacement: the tire sidewall and the tread edge are circled There are many small triangle patterns Move horizontally along any triangle pattern to the tread pattern The pattern surface will be found to be higher than the tire inner pattern and lower than the normal tire pattern It is the safety line Exercise to it here means that the tire should be changed. In fact, it's okay not to change it, but the fuel consumption and handling performance and braking ability have been reduced too much.

Especially on rainy and snowy days.

Don't forget that when the tires wear out 2w-3w kilometers, the front wheel should guide the front wheel, and the rear wheel (except for four-wheel drive vehicles) should have different wear on the front and rear wheels.

The life of a tyre is related to many factors, such as climate, road, driving style, installation, maintenance and repair. According to international regulations, if the tire is used normally, the tire must be replaced when it is ground to a tread depth of millimeters. Almost all tires have a mark at a tread depth of millimeters, known as the tread wear indicator TWI.

Ordinary tires can be used for 5-100,000 kilometers if they are used normally, of course, in addition to the service life, tires also have comfort, handling, grip, etc., which is also the competition of different brands of tires. A good brand, its comprehensive ability is strong.

Regular tires are valid for five years after production, so we recommend that you have to replace them after four to five years of use, regardless of whether they are worn to the millimeter. At present, there are no clear regulations on the wear and tear of tires in China, and the above suggestions are based on European regulations.

In addition, if a tyre fails, such as a cut on the sidewall, it must be replaced immediately.

Hello! The service life of the tires is judged based on the actual use of the tires, such as road conditions, driving style and daily maintenance. Therefore, it is difficult to give a specific figure on how long a tire will last.

When your tire tread is worn to the limit mark, i.e. the tread depth is less than millimeters, it must be discontinued. If there are numerous small cracks in the tread groove or sidewall of your tire, it is a sign that your tire has deteriorated and needs to be replaced.

In addition, you should not continue to use it if your tread is deformed or bead is damaged.
