How Do Run-Flat Tires Work?

Run flat tires

A common question I get asked here at work is “How do run-flat tires work?” Run-flat tires are a great invention that allows you, the driver, to make better decisions as to what you do when you realize you have a flat tire. First, the sidewalls of these tires are designed to withstand the weight of the car when your tire loses pressure. After all, when you have properly inflated tires, the air is what carries the weight of the car, not the tires. Secondly, these tires have a redesigned bead to maintain the connection between the tire and the wheel, so once you lose tire pressure, your tire stays attached to the rim. This also prevents your wheels from ever hitting the ground.

Most run-flat tires can withstand about 50 miles, but some have been shown to go over 200! With that being said, these tires are not meant to be driven without proper tire pressure, they are merely a safety precaution to allow you to get off the side of the road and to a tire dealer or repair shop.

There are a few things you should take into consideration before purchasing a car with run-flat tires.
1. These tires are heavier and will hamper your car’s efficiency.
2. These tires are NOT cheap!
3. Once a run-flat tire has been punctured, it cannot be patched.

We recommend tire pressure monitoring systems that will notify you, while you’re driving, if one of your tires is dangerously low. The combination of run-flat tires and a TPMS is your best defense against ending up on the side of the road with a flimsy jack underneath your car. Come by and let us show you some of the models that they come standard on.
