How to Check if a Tire is Run-Flat?

[Cheryl]

To determine whether a tire is a run-flat, you can use the following methods: 1. Check the sidewall markings—special symbols will follow the tire specifications on the sidewall; 2. Consider the vehicle model—mid-to-high-end models are often equipped with run-flat tires; 3. Examine the tire model—run-flat tires typically have an aspect ratio below 55; 4. Place the tire flat on the ground and stand on it—if the sidewall is hard, it's a run-flat tire. A run-flat tire consists of an outer tire, a standard inner tube, a spare inner tube, a steel rim, a gas generator or air chamber, a pressure sensor, and a control unit. Precautions for using run-flat tires include: 1. Avoid speeding to prevent rubber aging, delamination, or bursting; 2. Use low-pressure tires to improve ride comfort and steering stability, preventing blowouts; 3. Rotate tires regularly to extend their lifespan; 4. Maintain standard tire pressure to avoid excessive wear.
