A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Toyota vehicles are equipped with either conventional or run-flat tires. Sometimes punctures may occur as a result of contact with road debris or other hazards. If a puncture occurs, it may be possible to repair the tire and return it to service. With a conventional tire it is not possible to drive for an extended amount of time with the tire at low pressures as damage to the tire may occur. With run-flat tires, due to reinforced sidewalls, it is possible to drive for up to 100 miles at speeds less than 55 mph with little or no damage to the tire. The U.S. Tire Manufacturers Association (UTSMA) provides guidelines and recommendations for tire repair and replacement. It also provides information related to: ? Basic tire information ? Tire maintenance and safety ? Driver education, tire safety curriculum.
