Differences Between Run-Flat Tires and Regular Tires?

[JoelRose]

The main differences between run-flat tires and regular tires are as follows: 1. The thickness of the tire sidewall varies. Regular tires have very thin sidewalls, causing the tire to completely collapse when it loses air pressure. In contrast, run-flat tires have an additional layer of rubber on the sidewall, significantly increasing its rigidity. This rubber layer can still support the vehicle and allow it to drive at a certain speed even when the tire is deflated. 2. The suspension systems for vehicles equipped with run-flat tires and regular tires differ. Models with run-flat tires have specially tuned suspensions. If regular cars are retrofitted with run-flat tires, the ride comfort will be significantly worse, the shock absorbers will wear out quickly, and the vehicle's handling will also change. Not all car models are suitable for retrofitting run-flat tires. 3. Differences in comfort and repair costs. Although run-flat tires can prevent loss of control during a blowout, they also have several drawbacks, such as poor comfort, high cost, and difficulty in repairs. It is particularly important to note that while run-flat tires can support the vehicle for a certain distance in a deflated state, this still causes significant damage to the tire.
