Over the years I have gotten a few screws in either my tires or my wife's. Not often, but it happens. If it's center of the tread (not sidewall) I use the standard auto store plug kit and haven't had issues. Pull the screw, stick in the rasp tool, then put the plug in and trim it. Solid, every time and never thought twice about using them as it is an immediate fix at home without running to a tire shop... So, I had a screw last month in my Nokians and did the usual plug repair. I'm now have a slow leak. I lose 1-2 psi a week. I went to a couple tire shops and they won't touch a tire that has been plugged. They say the warranty is void and if the steel belt was compromised and the tire blows, they would be liable. So, for running over a screw, the only option they give is to buy a new tire if you don't bring it to them to remove the screw from the start. Does anyone have suggestions to re-do the repair? I do not have the capability to remove my tire and patch from the inside. I have seen some people use the plugs and gum them up pretty good with glue to further glop up the hole. I have never removed a plug before so I don't even know if that's worth doing. Thanks for any tips. If I have to buy two new tires, I will, but wanted to check for options first.
