<h2>Bridgestone DriveGuard 255/45ZR18 99W</h2><p><strong>OVERVIEW</strong></p><p>Run-flat tires allow a driver to keep going up to 50 miles even after complete loss of inflation pressure, and the Bridgestone DriveGuard features run-flat technology in a touring tire. The DriveGuard utilizes a reinforced sidewall and casing for rigidity, cooling fins that help with heat dispersal, and an all-season tread pattern for year-round traction and responsive handling. Additionally, the DriveGuard is backed by a 50,000 or 60,000 mile limited manufacturer tread life depending on its speed rating.</p>
