Understanding Run-Flat Tires
Run-flat tires are a type of tire that enables you to keep on driving despite getting a puncture. These tires are designed to keep you on the road without deflating completely, which can prevent you from getting stranded in a dangerous location.
In this section, we will discuss the key points of run-flat tires, including their benefits, disadvantages, and signs that they need to be replaced.
What Are Run-Flat Tires And How Are They Different From Regular Tires?
- Run-flat tires have reinforced sidewalls that support the vehicle’s weight when the tire loses air pressure, whereas regular tires do not have this feature.
- The reinforced sidewalls allow drivers to continue to drive on a flat tire for a specified distance at a limited speed, safely reaching the nearest service station or auto repair shop.
