What is the Difference Between Run-Flat Tires and Regular Tires?

Run-flat tires and regular tires differ in the following aspects: 1. Appearance: Run-flat tires have special markings, usually located after the specifications on the tire sidewall, whereas regular tires do not. 2. Structure: The sidewalls of run-flat tires are thicker compared to the relatively thinner sidewalls of regular tires. Run-flat tires, also known as zero-pressure tires, were developed primarily to address the frequent occurrence of blowouts during high-speed driving, which often leads to traffic accidents. In addition to the functions of regular tires, run-flat tires can allow a vehicle to continue driving for a certain distance even when the tire pressure is zero, typically up to 80 kilometers at a speed of 80 kilometers per hour.
