Most tire service locations and tire dealers have trained tire technicians, the required tools, and tire repair products to make a proper, safe tire repair. Ask these questions of any shop to which you take your tire to be repaired:
Do you repair tires using Industry Approved methods, a rubber plug to fill the injury and a patch for the inner liner or a plug/patch combination unit?
Do you employ trained tire repair technicians?
Do not have your tire repaired with any plug or string/rope product from the outside only. These tire repair products do not meet Industry Standards and are not considered to be permanent repairs. These repairs also void most tire manufacturers warranties.
