1999–2001 Ford F-550 Recall

On certain vehicles, the automated valve stems may have been over inserted into the wheels during installation. This could tear the rubber bulb at the base of the valve stem and result in loss of air. If air pressure is not maintained, the tire may operate at extremely low inflation pressures. Since commercial truck tires have steel cords in the sidewall, operation at extremely low pressures could result in sidewall zipper failures either during vehicle operation or during inflation of the tire. A potential for personal injury exists if safety standards are not followed while inflating and zipper failure occurs. Correction: Valve stems will be inspected for leakage and if leakage is found, both valve stem and tire will be replaced.
