Is Pirelli Run-Flat Tire a Bulletproof Tire?
2 Answers
Run-flat tires, commonly referred to as bulletproof tires, are abbreviated as RSC in English. Here are the detailed explanations: Inflated Tire: The sidewall of an inflated tire is the main part that supports the vehicle's weight, especially for tires with a larger aspect ratio, where the sidewall is very "thick." A severe "blowout" usually causes an instant collapse of the sidewall, leading to an immediate loss of support from the tire and a sudden change in the vehicle's center of gravity. Deflation: With RSC, even when the tire is deflated, the vehicle can still travel 250 kilometers at a speed of 80 km/h. RSC can almost prevent major safety accidents caused by blowouts on highways and also avoids the risky situation of changing tires on highways.
As an enthusiast who has studied tires for many years, I remember that Pirelli's Run Flat tires are a typical example of run-flat tire design. Their working principle involves adding reinforced layers inside the tire, allowing the vehicle to continue driving for about 80 kilometers even in case of a puncture, avoiding the risk of emergency stops on the road. I've driven cars equipped with these tires and felt very reassured, especially during long-distance highway trips, without worrying about the danger of a flat tire. However, they are not a perfect solution—comfort is slightly compromised, the stiffer sidewalls increase the bumpiness while driving, and regular checks are essential. If used for too long after a puncture, they can exert extra pressure on the wheel rims. Overall, choosing a reputable brand like Pirelli ensures reliable technology and significant safety improvements.
