What are the effects of replacing run-flat tires with regular tires on a car?
2 Answers
For vehicles that have not undergone specialized adjustments, using run-flat tires can reduce driving comfort and handling performance. Car models equipped with run-flat tires feature specially matched designs in the chassis, suspension, and wheel rims, delivering superior performance in road driving stability. Below is extended information about tires: 1. Run-flat tires: These are one of the important components of a car, with most vehicles using regular tires. Some higher-end car models are equipped with run-flat tires, which also offer excellent performance in road driving stability. In the event of a tire deflation, the vehicle can still travel 250 kilometers at a speed of 80 km/h. 2. Balancing test: After replacing tires, it is essential to perform a dynamic balancing test on each wheel to prevent abnormal vibrations during high-speed driving. 3. Tire lifespan: The service life of tires is generally around 2-3 years or 60,000-100,000 kilometers. Chinese regulations require tire replacement when the tread wear reaches 1.6mm.
As a veteran driver who places great emphasis on safety, I must say the most immediate impact of switching from run-flat tires to regular tires is the significant increase in safety risks during a blowout. Run-flat tires allow you to continue driving for dozens of kilometers even when deflated, enabling you to pull over safely, whereas regular tires can lose control almost instantly upon a puncture—especially dangerous in high-speed emergencies. Additionally, many vehicle designs originally rely on the stiff sidewalls of run-flat tires to support the suspension system. After switching to softer regular tires, prolonged driving may subject the chassis and suspension to extra impacts, accelerating wear and tear. Unless you’re fully prepared with a spare tire, tire repair kit, and portable air compressor, I advise against making the switch lightly. After all, safety is no trivial matter—always double-check whether your tire pressure monitoring system is compatible to avoid false alarms or unresponsiveness. In short, sacrificing a bit of comfort is far better than risking your life.
