Is the Hongqi HS7 tire a run-flat tire?

[Rebecca]

Hongqi HS7 tires are not run-flat tires. The original tire specifications for the vehicle are 255/50R19 and 255/45R20. The tire specification data has specific meanings, for example, in 255/50R19, 255 represents the section width, 50 represents the aspect ratio, R represents the tire structure, and 19 represents the tire diameter. Below is more information about run-flat tires: 1. Run-flat tires do not mean they won't go flat; instead, they have thickened sidewalls that allow the tire to support the vehicle even after losing air, enabling the driver to reach the nearest repair point. 2. Run-flat tires are now being used in various types of vehicles, but due to their higher cost compared to regular tires, their adoption rate is still relatively low. Generally, vehicles equipped with run-flat tires must drive at speeds below 80km/h after a tire blowout and should not be used continuously for more than 100 kilometers.
