If you need a tire that doesn't have to be changed immediately in the event of a flat tire, you should be interested in run-flat tires. The run-flat tires are designed so that a hole does not immediately lead to a flat tire and the vehicle can continue to drive at a reduced speed. This means that a replacement tire is not absolutely necessary, but the damaged tire can be easily replaced at tire dealers or specialist dealers. In principle, the system is similar to one Notrad, The advantages, but also the disadvantages, of such a tire are explained below.
Run-flat tires - unknown but useful
Run-flat tires are particularly interesting for people who do not want to worry about the replacement tire or simply cannot change a flat tire themselves. With a run-flat tire, you can continue to drive a few kilometers with a smaller hole in the tire. This property is considered a huge advantage. However, the tires also have disadvantages, which are explained in more detail below.
Run-flat tires - how are they constructed?
The run-flat tires, more precisely the tire beads, remain fixed on the rim, even if there is a loss of tire pressure. The tire does not come off if the wheel is damaged. Furthermore, a run-flat tire is designed so that it can maintain its shape with a hole for a certain time. These advantageous properties result from reinforced side walls. Even if the side walls are perforated, the reinforcement keeps the shape. However, the tire also has disadvantages. As a result of the structure of the run-flat tires, damage can go unnoticed and the tire can continue to be exposed to extreme loads. It is also not possible to repair a run-flat tire. The tire variant is also more expensive than conventional tires.
Run-flat tires - what are the advantages?
Runflat tire drivers do not need to use replacement tires. This leads to more space in the trunk. The driver does not have to wait for a breakdown service in the dark. The tires are designed for speeds of up to 80 km / h and a range of 250 kilometers and are therefore still sufficient as replacement tires. Run-flat tires are available in different versions. There are models that can also drive without air. The tires are also referred to as so-called run-flat tires and are used, for example, in sports vehicles. When buying, you should pay attention to high-quality, tried and tested variants. It is helpful to choose run-flat tires from the brand manufacturer.
What are the disadvantages of the tires?
Damage to the tires may go unnoticed. In addition, the tires are more expensive than conventional tires. Changing run-flat tires usually costs more than changing conventional tires. Run flat tires cannot be repaired. It is also reported that driving with run-flat tires is not as comfortable as driving with conventional tires. The differences in driving style shouldn't be very big, but still be noticeable for some. In contrast to AG vehicles, particularly sporty cars such as BMW M-vehicles have therefore been delivered without run-flat tires for years. Here the manufacturer relies on the M Mobility system, which should also ensure that the tire can be used again for a short time. So if you don't expect a puncture in the tire often, drive little or are almost exclusively in the city, the question arises whether run-flat tires are worthwhile.
