Disadvantages of Run-Flat Tires You Should Know
When considering run-flat tires, you should be aware of a couple of significant drawbacks. Their stiffer sidewalls can lead to a rougher ride, making your driving experience less comfortable. Plus, with limited replacement options available, you might find it challenging to find a suitable tire when it’s time for a change.
Limited Replacement Options
Limited replacement options stand out as a significant drawback of run-flat tires. Unlike conventional tires, which you can easily find at tire stores, run-flat tires often come with limited availability. Most models are original equipment, primarily available on new vehicles, leaving you with few aftermarket options. This scarcity can be frustrating, especially in less populated areas where smaller retailers may not stock a wide selection. Additionally, the higher cost of run-flat tires—ranging from 25% to 100% more than regular tires—adds to the challenge.
