Run Flat Tires
The side of the road is not a fun place. In fact, it can be dangerous. Thankfully, there’s run flat technology. Run flat tires allow you to drive for a limited distance and reduced speed after a puncture or other event has resulted in either a drop in tire inflation pressure or a complete loss of inflation pressure. For example, MICHELIN® Zero Pressure (ZP) tires provide run-flat technology that allows you to drive up to 50 miles at 50 mph with a flat tire.
Never mix run flat tires with tires that do not have run flat technology (conventional tires) unless in an emergency situation on a limited, temporary basis. The conventional tire should then be replaced with a run flat tire as soon as possible. It is not recommended to mix different run flat technologies/products.
