Hello everyone, I just found out that Discount Tire no longer patches tires that have been previously plugged. 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. 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.
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. I was shocked since I have done the same thing in the past and they never gave me any trouble. 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. Seems like BS since a screw or nail could do the same thing, but I'm no expert. I called another Discount Tire to verify and they told me the same thing. Fortunately since I have their road hazard protection insurance they are going to replace it for free since they won't patch it.
So next time you get a flat tire, think twice before plugging it if you intend to have it patched later because you may not be able to anymore.
