How Run-Flat Tires Work: Introduction
Subjected to unimaginable vagaries, the tires on our cars are tasked with so many very important duties. They keep our car adhered to the road’s surface. They support the weight of the car. They have to crunch through snow and ice. They slog through mud. They slice through standing water. They fend off road debris made of glass, metal and other potentially destructive materials. They have to deal with searing heat and paralyzing cold. They pound over rocks and gravel and through it all, they transfer power from our engines to the ground and execute the changes of direction we request from the steering wheel.
It’s truly remarkable how one of the most critical aspects of our cars is also the most vulnerable. Given all they have to go through, it’s a true testament to the advancements in tire technology we don’t find ourselves on the side of the road repairing flat tires every day.
Regardless of how substantial looking the tire on your vehicle may be; it’s the air inside it that actually carries the weight of your vehicle. When that air escapes, the tire is pretty much rendered useless.
Fortunately, time and technology march on…
