Can the tires repaired by the tank car manufacturers still run at high speed?

Can a repaired tire still run at high speed? Tank truck manufacturer: The repaired tires can actually be used normally and can also be used on the high-speed.

However, it should be noted that if the tire side damage or the crown damage diameter is more than 6mm, it is not recommended to continue to use or run at high speed even after repairing the tire.

In addition, the stability of the tire after the repair is related to the method and position of the repair, if it does not meet the requirements, it will also affect the safety of high-speed driving.

In general, in order to ensure the safety of daily driving, it is not recommended to repair the obvious damage to the tire side or the damage of the tire crown is too large.

Some tire manufacturers stipulate that after strict repair, the speed limit should be reduced

Different tire manufacturers, the speed regulations after repairing the tire are not the same. The so-called speed rating is what we can see directly on the side of the tire, it's a letter. For example, 225/55 R17 97V, the letter "V" means that the speed of this tire is 240km/h. It used to be V but it's downgraded, it's down to H, 210km/h. Many tire manufacturers clearly pointed out that the repaired tire should be downgraded to the speed limit grade, because China's high-speed speed limit is 120km/h, even if it is reduced by a grade, it is much higher than the speed limit of 120km/h, so you do not have to worry too much about the high-speed, you can open normally.

Tanker manufacturer: What kind of tire can't be repaired?

In general, only tires with a puncture in the tread or crown can be repaired. Bridgestone's official website also says: the damage to the body and the wire strap layer cannot be repaired, and only the damage to the crown part can be repaired.

The main structure that affects the safety of the tire is the cord layer between the tread and the bottom of the tire. In general, the cord layer is used to ensure the strength of the tire, bear the load and maintain the stability of the tire. It is like the pillars inside the house, supporting the frame of the whole house. In the final analysis, the main structure that affects the safety of the tire is the curtain layer between the tread and the base of the tire. The cord layer of the crown part is generally five layers, including one layer of nylon cord, two layers of steel cord, two layers of polyester fiber cord, a total of five layers of cord layer.

The damage of the crown diameter below 6mm will basically not affect the role of the curtain layer, and the impact on the structure of the tire itself is very small. If more than 6mm is inserted into the hole, it may have an impact on the curtain layer, and if more than 6mm is inserted into the hole, it will not be possible, and it may have a certain impact on the strength and structure of the curtain layer, although it is not perfect, but the security risks are greatly increased.

This is like when we buy a house to decorate, we have to smash down individual walls, adjust the layout of the house, we smash down the non-load-bearing wall in the house, that is of course no problem, if you directly smash down the load-bearing wall, then you say that the house is dangerous, is this similar truth.

The strength of the tire side fabric layer is relatively poor and fragile, and the strength of the tire side fabric layer is much worse than that of the tire crown, generally 1 to 2 layers, once damaged, it will affect the working stability of the tire at high speed. In the same way, tires such as side bulge should be replaced immediately and are extremely prone to blowouts.

At present, what is the most safe and reliable method of repairing a tire? At the beginning, I said that in addition to the factors of the tire itself, the method of repairing the tire also affects the stability of the tire after repairing the tire. At present, there are many common tire repair methods, such as tire repair fluid, wear rubber strips, patches, mushroom nails, etc., the price is also 369 and so on.

However, mushroom nail tire repair is currently the most safe and reliable method of tire repair, although it is very expensive but it is the most stable, which can ensure the high-speed driving of the tire after repair.

Repaired tire is relatively fragile, it is recommended to change the position

However, the repaired tire has been damaged after all, and the performance of the intact tire is still worse, and the safety risks are larger, therefore, it is also necessary to relocate the repaired tire.

For example, the front wheel of the front drive is tied after repair, my personal recommendation is to change this tire to the rear wheel, similarly, if it is the rear wheel of the rear drive, it is recommended to replace the repaired tire with the front wheel, in short, try to stay away from the driving wheel.

Tank truck manufacturers summary:

As long as the tire is repaired well in accordance with the rules, there is no problem on the high speed, and there is no need to worry about opening 120 yards. However, the position and method of repairing the tire should meet the specifications.

Tires are directly in contact with the ground parts, it is directly related to the safety of everyone on the car, so no careless. In addition, we should develop the habit of checking the tires before going on the highway, so that we are prepared.
