Can an overloaded truck really blow a tyre out?

Every car tire has a load index that reflects the maximum load value of the tire. If you look closely at the parameters of the sidewall of the tire, the last English letter will be removed, and the last Arabic numeral will be the load index. In general, the load index of domestic tires is above 90, and the corresponding maximum load is 600-800 kg, while the total of four tires is tons.

For six-axle 22-wheeled heavy-duty trucks, the tire load index is generally above 150, and the corresponding weight is more than 3 tons, so the 22-wheels add up to about 60 tons or 70 tons.

Speaking of which, many people will wonder why some trucks are overloaded to almost 200 tons, even though the total weight of heavy truck tires is only 60 to 70 tons. In fact, it is likely that you have misunderstood the maximum weight of your tire. The maximum weight does not refer to the weight that causes the tire to collapse, but to the fact that once the load exceeds this value, the various performance of the tire will be greatly reduced and exceed the reasonable range.

For example, tires will become very stiff, vibrations will become noticeably greater, wear will increase, life expectancy will decrease, and so on. However, even so, the tires are far from collapsing and bursting. Frankly, the car is not very good because the tires are in bad condition.

However, if you really want to drive, you can still drive reluctantly.

What is the true limit of a tire collapse (burst)? According to the design requirements, the tire burst limit can reach 5 times the maximum load-bearing capacity. Thus, according to this calculation, even if a heavy-duty truck is loaded with 200-300 tons of cargo, it will not have a flat tire.

The tire pressure is the same as the load. When it comes to inflating tires, although we always worry that too many tires will burst, the truth is that we are unfounded. Because the maximum permissible tire pressure in a domestic vehicle is usually higher than the bar, it is theoretically possible to burst only when the tire pressure is higher than 15 bar, which is much more than the power of a normal air pump.

As a result, it is difficult to get a tire to burst, whether by inflating or loading it.

But there are occasional stab wounds on the road, so what the hell is going on? Because other factors can also cause tire bursting, such as scars on tires, aging, external impact, etc. Although it is difficult to directly cause a puncture due to tire overload or overpressure, these factors can increase the success rate of a puncture.

This is why the vast majority of those with flat tires on the road are large vehicles, and domestic vehicles are almost invisible because the overload of large vehicles is much higher than that of domestic vehicles. Of course, the tire burst mentioned here refers to the ** of the tire, not the nail puncture due to a flat air.

Whether it's through weights or pumping, it's hard to get a tire to pop.

I think it should be, because tires also have a limit to bear, and if they are too heavy, they will burst.

I think it will, because tires also have a weight that can be carried, and if you exceed the limit, it will naturally be **.

Yes, because the carrying capacity of the tires is limited, and not only will the tires be damaged, but also the impact on the car will be great.

I think so, but be aware of other causes that may cause a puncture.

This should be possible, after all, tires are not capable of withstanding infinite forces.

This situation is generally not possible, usually when the temperature of the car tires is too high.

Obviously, the maximum load of the tires of heavy trucks is only sixty or seventy tons, so some trucks have been overloaded to nearly 200 tons, why haven't the tires been blown up? In fact, this is likely to be your misunderstanding of the maximum load of the tire, the maximum load does not refer to a weight that makes the tire collapse, but refers to the fact that once the load exceeds this value, the performance of the tire will be greatly attenuated, and beyond a reasonable range. For example, tires will become very stiff, vibration will become significantly larger, wear will increase, life will decrease, and so on.

But even so, the tires are still far from a collapse and puncture, to put it bluntly, at this time, it's just that the car is not very easy to drive because the tires are not in good condition, but if you really want to drive, you can still drive reluctantly.

The tires of the trucks are specially made and generally do not burst.

This should be unlikely, after all, tires are capable of carrying a lot of weight.

As we all know, tires are the parts that are in direct contact with the ground when the truck is moving, and bear the weight of the whole vehicle. It is supported and buffered by an internally filled gas state and structure.

The pressure of the gas in the tire is what we often call the tire pressure. If the tire pressure is too high or too low, a puncture may occur. Therefore, there is a certain relationship between tire pressure and tire load.

Correct tire pressure is beneficial for the load bearing of the vehicle and improves safety. Secondly, it is necessary to understand the index performance of the tire. Generally, the side of the tire is marked with a row of numbers and letters that indicate the size, load, and type of tire.

Take 195 55 r15 85 v, for example. 195 means that the cross-sectional width of the tire is 195 mm. The latter 55 refers to the flattening rate of the tire, that is, the ratio of the cross-sectional height to the width of the upper section.

After that, the letters and numbers represent the tire type and rim diameter. R stands for radial tires, which are basically tires for all domestic vehicles, and D stands for bias tires, which are generally used by large trucks or low-speed construction machinery vehicles.

After that, 85 is the load index of the vehicle. However, if you want to know the maximum weight that a tire can hold, you need to refer to the load index table. The comparison of the 85 and 515 in the table shows that the maximum weight that the tyre can carry under standard conditions is 515 kg.

But there's more to a truck than just one tire. The force on each tire is different. So even if the vehicle is carrying a lot of weight, if multiple tires are carried together, the distributed weight will be much smaller, and there will be no punctures.

How much load can a truck tire withstand, and why don't the tires burst when the truck bends the bridge? For example, if a vehicle weighs 180 tons and has 18 tires, then the load of each tire becomes very small. But the forces on the front, middle, and rear wheels are not the same.

In addition, tires have good wear resistance and pressure resistance, elasticity and toughness, and are not easy to puncture.

Overloading is a very dangerous thing, but there will still be many people on the road with overweight goods for their own benefit. Not only did he damage a lot of roads, but he also made fun of his own life. It's irresponsible to yourself and others.

Therefore, small cars should keep a certain distance when they see a big truck and be vigilant. At the same time, I implore everyone not to overload and cherish life!

It must also be afraid of a puncture, if the temperature is relatively high, and if you don't pay attention to it during driving, it will also cause a puncture, and there are so many wheels to ensure safety, so that you can balance during driving.

No, there are many wheels in trucks, and each wheel has its own corresponding position, and the bearing capacity is very large, and it is very dangerous to have a puncture.

No, even though there are so many wheels, large trucks are also afraid of flat tires, and they can't drive after a flat tire.

No matter how many wheels the truck has, the truck is also very afraid of flat tires. Because a flat tire will slow down the truck on the road, and a flat tire may also cause an accident and hit the subsequent vehicle and cause a traffic accident.

In fact, no, there are a lot of tires in trucks, but if there is a puncture, it is also very dangerous, and the impact on the truck is also relatively large.

No, the main trucks are very heavy, and without these tires, they can't lift the power at all, and the tires are just there to help run.

Of course I'm afraid. The reason why there are so many wheels in trucks is to maintain balance, not to prevent punctures.

It must be the fear of a puncture, and it is also the fear that the tire will not be able to bear such a heavy weight, so there are a lot of wheels.

The durability of tires is different from that of viaducts, and the durability of ordinary roads is also different. The weight of the bridges is on the piers, and the load on each bridge is limited. More dangerous than that. The vehicle drives on one side all the year round, which is easy to cause uneven force on the bridge, lose balance, and cause the bridge to overturn.

<> why can a truck knock a bridge down, but not a tire? The total weight of the truck girder excavation exceeds the standard load of the bridge by several times, so some bridges may be damaged by overweight. Cars, on the other hand, have multiple tires to share the weight, so one tire can only carry a few tons, so a big truck can crush a bridge without a single tire bursting!

A tire is a component that is in direct contact with the ground and carries the weight of the vehicle. And it itself depends on the state and structure of the internal filling gas, which plays the role of support and buffer.

Tire pressure has a certain relationship with tire load, correct tire pressure, is conducive to the load of the vehicle, but also improves safety. The side of the tire is marked with a line of numbers and words to indicate the size, load and type of tire. Take 195 55 R15 85 V as an example, 195 is the cross-sectional width of the tire is 195mm, and 55 is the flattening ratio of the tire (the value of the cross-sectional height to the width of the upper section).

The letters and numbers on the back represent the tire type and rim diameter. R is a radial tire, which is basically the standard tire for domestic vehicles. If the D is a bias tire, it is usually used for low-speed trucks or construction machinery vehicles.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if there are any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also talk to me more scum and interact with me, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

The tires are scattered in different places, and they have a high-end elastic rent, so that they can withstand some pressure evenly, and the force of the bridge is not particularly uniform, so it is easy to be crushed by the disadvantages.

Such cars generally have a lot of tires, and each number of Songqi tires will bear a part of the pressure, so it is difficult to crush, and the pressure that the bridge deck needs to bear is relatively large and easy to crush.

It is related to the bearing capacity of the bridge. The tires of the car have a strong pressure bearing capacity, and there will be multiple tires to support together.

The causes of a flat tire in a truck are as follows:

1. Insufficient tire pressure. If the tire pressure is insufficient, it is easy to bend and break the sidewall of the tire and burst. If the tire is flat due to valve wear and dust before going on the road, the tire pressure inside the tire is too low, and it is easy to cause a puncture;

2. The tire pressure is too high. It can cause the defective part of the tire (such as the part of the previous damage) to burst, which is more common in hot summer weather or when driving for a long time;

3. The vehicle is overloaded. The harm of overloading of vehicles to tires is self-evident, especially when we often see some large trucks overloaded on the highway, when tires are more prone to puncture accidents;

4. Drive past sharp objects at high speed. When the vehicle is driving at high speed, the tire rubs against sharp stones or other sharp objects on the road surface, resulting in air leakage and then puncture, which is also a common cause of accidents.

This is because the force is dispersed, the truck has n tires, the overloaded 180-ton car, at least the rear 12 wheels, then there are 2 wheels in front, 4 wheels in the middle, and the weight of 18 tires is also dispersed, plus the tires are elastic and tough, so it is impossible to **, but the bridge is different, because the load is on the pier, if the force is too heavy and uneven, the direct face is collapse! I hope this incident will let everyone know the dangers of overloading!

Because the car has many tires, not all the weight is pressed on one tire, and the tires are really strong. The load-bearing capacity of the bridge is limited, and the bridge is crushed, usually because the vehicle exceeds the weight limit of the bridge too much, or there is a problem with the bridge itself.

How many tons and how many tons are overloaded at most for a four-meter-two truck, what brand of tires is a good answer.

Overloaded large trucks generally use all-wire radial tires. This type of tire is characterized by the fact that it can run more quickly and can save fuel than bias tires, so it is quite economical to use such tires.

Identification and selection of tires.

1. If the outer edge of the tire is greatly worn, it means that the tire is often in a state of insufficient inflation, that is, the pressure is not enough;

2. If the inner side of the tire is worn and the outer edge is burr-like, it indicates that the tire is deformed and the symmetry of the two tires has been affected;

3. If the two sides of the tire landing part are convex and corrugated, it means that the shock absorber, bearing and spherical coupling and other parts of the car are seriously worn;

4. If the wear of the center area of the tire landing part is serious, it means that the tire is often in a state of overinflation;

5. If the tire pattern has been smoothed, the tire must be replaced, and the life of the tire is officially over.

The damage to the tires caused by the overloading of the vehicle is quite high, and it is recommended to use steel wire tires and recommend the brand Bridgestone or Michelin.
