Question: are zr rated tires repairable?
Answer: Can tires rated H (130 m.p.h.), V (more than 130 m.p.h.) or Z (more than 149 m.p.h.) be safely repaired? Yes, with some reservations. ... Most punctures can be repaired, and the tire returned to service, as long as the puncture is in the tread area. If the damage is in the shoulder or sidewall, however, replace the tire.
