Will stabbing a tire with a knife cause it to explode or slowly deflate?

Stabbing a tire with a knife will cause it to slowly deflate. Below is relevant information about puncture-proof tires: 1. Overview: Puncture-proof tires have a layer of high-molecular composite material bonded to the inner wall of the tubeless tire, presenting as a soft, solid gel state. The tire protection system includes comprehensive safety technologies such as tire blowout prevention, leakage prevention, noise reduction, energy saving, and maintenance. 2. Principle: When sharp objects like nails penetrate or are pulled out of the tire, the high-molecular composite material can quickly surround the object and seal the puncture hole in time, achieving a protective effect. 3. Other functions besides puncture resistance: Leak prevention, bullet resistance, buffering against blowouts, noise reduction, etc.
As an experienced automotive technician, I've seen numerous cases of punctured tires in the shop. I can definitively tell you that stabbing a tire with a knife usually doesn't cause an explosion, but rather a slow leak. Tires have a complex internal structure with steel belt layers and thick rubber. A knife puncture just creates a small opening, allowing air pressure to gradually escape rather than bursting instantly like a balloon. However, don't take it lightly - this process can happen quickly, with the tire going flat within minutes. Driving on a deflating tire can easily lead to loss of vehicle control, especially on highways, making it a serious safety hazard. Relatedly, I recommend drivers regularly check tire pressure and install a tire pressure monitoring system to detect abnormalities promptly. If this happens, immediately turn on hazard lights, pull over safely, and don't push your luck - have a professional repair shop replace the tire to avoid endless troubles.
Hey, my car enthusiast friends often discuss these kinds of issues. From my experience, stabbing a tire with a knife doesn’t result in an explosive scene—it usually just makes a hissing sound as the air leaks out rapidly, but it’s not an explosion. Although tire pressure is high, the thick rubber means a small cut will cause a slow leak. But it’s extremely dangerous: the car can suddenly become unstable. It’s manageable in the city, but on the highway, it’s a disaster—flipping over in minutes. Here’s some practical advice: don’t try this like in online videos; if you do puncture a tire, stop immediately and call a tow truck. Back to tire structure—why don’t tires explode? Because they’re designed to withstand impacts, unlike balloons that pop when punctured. Regular checks on tread wear during maintenance can prevent a lot of trouble.
