![]() Some kits also contain rubber cement to help create a seal between the string plug and tire. String plugs are typically supplied as part of a repair kit consisting of a reaming tool, an insertion tool and a few string plugs. Often times, this plug-only repair is a “string plug,” which consists of a 4 to 5 inch long woven cord that is covered with a tacky substance. The insertion tool is the removed, leaving the plug in the hole, and thereby filling it. ![]() This is one of the multitudes of reasons why a plug-only repair is an unsafe method.Ī plug-only repair is accomplished by inserting the plug through the outside of the tire with an insertion tool. It is impossible to inspect the cavity of the tire for any puncture damage without removing the tire from the rim. Technicians will often swab the tire with soapy water or dunk it into a tank to look for bubbles of escaping air. Therefore, unless there has been damage or the puncturing object is still protruding from the tire, it can be difficult to locate the puncture through a visual examination only. When tire rubber has been punctured, the hole tends to close up when the puncturing item us removed. The patch-only and combination repairs require the technician to demount the tire from the rim to examine the inside of the tire for damage and repair it from the inside. There are three common ways to repair a punctured tire: A plug-only, a patch-only repair or a combination repair.

I called another Discount Tire to verify and they told me the same thing. Seems like BS since a screw or nail could do the same thing, but I'm no expert. When I asked what the reason is, he said the plug may have allowed moisture into the belts and could have caused rust, so for safety they stopped patching previously plugged tires. I was shocked since I have done the same thing in the past and they never gave me any trouble. Well I just took that tire into Discount Tire to try to get it properly patched and I was informed that they no longer patch tires that have been plugged and my only option would be to replace it. A few weeks ago I got a screw in my tire and couldn't find the lug nuts for my spare (I have aftermarket alloy wheels and my spare is one of the stock steel wheels that uses different lug nuts), so I plugged the tire with my plug kit and pumped it up again as a temporary fix with the intention of having it patched later since patches are much more reliable in the long run. ![]() In the past I have plugged tires as a temporary fix and then had Discount Tire patch it when I had time, but I found out the hard way that they no longer do that. Hello everyone, I just found out that Discount Tire no longer patches tires that have been previously plugged. ![]()
