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. The P Zero PZ4 Run Flat has an asymmetric tread pattern with a focus on comfort and low road noise. Wide grooves help evacuate water and improve braking and hydroplane resistance. Based on the original equipment application this tire can be constructed differently to lean more toward comfort or performance based design.
