We’ve all been there. Your car starts driving a bit weird, you assume the worst and pull over to check it out. Just as you expected, a flat tire. The fastest way to bring your morning commute or family road trip to an abrupt halt. Wherever you’re going, you depend on your tires, and your tires depend on air. Unless they don’t.
Run-Flat tires aren’t a particularly new technology, they’ve been around since the 1930’s, but they haven’t gained much traction until recently. (No pun intended) They are essentially as their name suggests, tires you can run on even after they have gone flat. There are two main types of Run-Flat tires, Self-Supporting, and Support-Ring.
