Can a run-flat tire really explode?
In recent years, many brands led by BMW have popularized the use of "run-flat tires" one after another, but "run-flat tires" are just a general term. The so-called run-flat tires are only slightly thicker than ordinary tires. Therefore, the probability of a tire blowout is smaller, but it does not play a role in explosion protection. Their real name is: Decompression Continued Running Tire. As the name implies, it can continue to run even when the tire pressure is too low or even 0, provided that it maintains a reasonable speed and does not run too far, such as running 80 kilometers at a speed below 80km/h.
But it should be noted that even if it is a decompression running tire, driving at low tire pressure will cause irreversible wear to the tire, so even if your BMW has a decompression running tire, after finding that the tire pressure is abnormal , and please find a tire shop for maintenance as soon as possible.
Regarding the commonly known "run-flat tire", it is added that the reason why it can continue to drive under the condition of low tire pressure is because it has a relatively strong sidewall. Therefore, this type of tire itself is relatively hard, and its shock filtration performance is slightly worse than that of the same brand, same series and same specification of non-loss running tires.
But also because the sidewall is harder, it can provide better lateral support, and the handling of the vehicle will be more agile.
