Let's find out with THANH PHONG AUTO in the article below!
Run-flat tires are also known as "anti-air tires" and have the ability to operate in conditions where the tire has lost all pressure, meaning the pressure is now 0.

On the market today there are 2 main types of Run-flat tires including:
Self-Supporting: This is a type of tire whose sidewall is made from hard and durable rubber. It is the type that can withstand the entire weight of the vehicle when the tire pressure suddenly "drops" to the lowest level. This type of tire often comes with a tire pressure monitoring system (which is standard equipment on new car models) to update the tire situation in real time for the driver to understand in detail.

Auxiliary Supported Auxiliary tires do not use hard and durable rubber. It is just a combination of a special rim and the inside is reinforced with a steel ring that can withstand the weight of the vehicle.
Auxiliary Run-flat tires
Run-flat tires first appeared on some car models since 1994. However, they were not popularized in the market due to their high cost.
Run-flat tires are standard equipment on most BMW models, except the M Series. Although there are many advantages in terms of flexibility and practicality, not all vehicles are suitable for Run-flat tires because this type of tire requires a suitable combination with the suspension system. Below are some pros and cons of this type of tire.
Very safe: Run-flat tires will limit accidents caused by leaking tires or sudden punctures. The fact that your tires still operate well after being punctured will help the driver control the steering wheel. This special ability plays an important role when your car has a problem at night, the road is deserted, or there are no conditions to stop the car to handle the problem.
Save a portion of fuel, create spacious space: No need to carry a spare tire, tools to change the spare tire will help your vehicle reduce a portion of its weight, save operating fuel, Create a spacious space and end the trip early even if an incident occurs.
In addition to its advantages and high practicality, the tire still has many disadvantages that prevent it from being widely popular and completely replacing regular tires:
High cost: This is also the reason why the Run-flat line is rarely used in popular cars. According to statistics, the price of Run-flat tires is 30%-40% higher than regular tires. Besides, Run-flat tires are heavier than regular tires, so the fuel consumption of vehicles using Run-flat tires will be 1% higher, which is not a small cost for those who regularly drive. long distance vehicle.
Difficult or impossible to recover from a puncture: Because it is designed to withstand the weight of the vehicle when the tire pressure is 0, the tire wall will be easily damaged and difficult to recover. The manufacturer recommends that users replace tires with new ones and should not reuse punctured or torn tires.
Does not bring a feeling of "adventure" to the driver: Run-flat tire walls are often thinner and harder than regular tires, so they absorb less shock during vehicle movement, creating loud noise. Currently, some tire manufacturers have also added a series of new technologies to overcome the above disadvantages but still do not bring comfort like regular tires.
Not effective when the vehicle is on a long, deserted road: Run-flat tires can only operate for a maximum of 80 km when punctured. So what happens if there is no garage or repair point to help you along the way? That's why we sometimes still see the importance and necessity of a spare tire right then and there.
Not suitable for slippery, wet, and low-temperature road conditions: Because the traction of Run-flat tires is not good, there is a potential risk of unsafety when operating in slippery, wet road conditions. Users must pay close attention to this issue.
