This illustrated wall chart outlines the safety procedures for any tire suspected or not suspected of having been operated under-inflated and/or overloaded. It covers new, used, retreaded, or repaired medium and light truck tires. The wall chart is a supplement to RMA’s Tire Information Service Bulletin (TISB) Vol. 33 of the same title. Be sure to read and understand both documents and pay attention to all warnings. The TISB Vol.33 is available as a FREE download here. You can also download a FREE PDF PowerPoint version of the wall chart.
