Are run-flat tires a good alternative to carrying a spare tire? Run-flat tires offer the convenience of driving without stopping immediately after a puncture, eliminating the need for a spare tire. However, they come with trade-offs, including higher costs and a firmer ride. Understanding their benefits and drawbacks helps determine if they are the right choice for your vehicle.

Run-flat tires are designed to allow you to continue driving after a puncture, typically for 50 miles at speeds up to 50 mph. This feature eliminates the immediate need to change a tire on the roadside, providing safety and convenience.
How Do Run-Flat Tires Work?
Run-flat tires use reinforced sidewalls that support the vehicle’s weight even when the tire loses air pressure. This design helps maintain control and stability, allowing you to reach a repair shop safely.
