The Pirelli P Zero PZ4 Run Flat sidewalls provide self-supporting capability for up to 50 mph for 50 miles. TPMS sensors are a must when running run flat tires as it is very difficult to recognize that a tire has lost air pressure.

Based on the original equipment application this tire can be constructed differently to lean more toward comfort or performance based design.
