WHAT IS THE REPAIRABLE AREA OF AN RFT (RUN FLAT) TIRE?
No tire, regardless of its design or quality, is indestructible. RFT tires can be ultimately rendered unusable due to a puncture or other road hazard as well as from improper run-flat or low pressure operation. Some punctures may be repaired under certain circumstances, with restrictions and subject to prescribed procedures. When driven flat or with low pressure, factors affecting reparability include vehicle speed, load, handling and maneuvering; the amount of inflation pressure lost; and ambient temperature. In any situation, the extent and location of direct damage from a puncturing object or other road hazard are also critical factors. RFT tires are not repairable in any of the following situations: • If the tire is described as, “Do Not Repair” on the sidewall. • If the tire was operated with inflation pressure less than 15 psi (100 kPa). • Abrasion or other damage is present on the exterior tread, sidewall or bead areas. • Abrasion, wrinkling, or separation is present on the tire
