A flat tire is perhaps the most inconvenient inconvenience out there. It brings all motion to a screeching halt, as you must stop driving to avoid further damaging the tire, the wheel and your vehicle. And that's why many vehicle manufacturers use run flat tires as Original Equipment—a little added technology goes a long way to curb the damage (and the annoyance).
Despite the fact that research and development efforts have improved tire durability and longevity, flat tires happen. Run flat tires temporarily maintain vehicle mobility using standard Original Equipment and aftermarket wheels, giving drivers like you more flexibility when deciding where and how to have flat tires repaired. These technological advances can be categorized into two groups:
Self-Sealing Tires fix their own punctures. There's an extra lining beneath the tread that's coated with a sealant, and it can permanently fix most punctures almost instantly. (Example: Continental ContiProContact ContiSeal Grand Touring All-Season Tire)
Self-Supporting Tires feature a stiffer internal structure that is strong enough to support the weight of the vehicle in the event of a tire puncture that leads to loss of air pressure. (Example: Bridgestone Turanza EL42 RFT)
