GET NEW TIRE
Everything I have ever read indicates that plugging tires in general is not a good long term solution, although you will find plenty of instances where people have gone many miles with plugs. Many people do things every day that defy the odds. Still does not make the decision the correct one.
The trouble is that failure can be catastrophic, not merely inconvenient. What will you pay to assume a risk of death, injury, or complete destrucion of your ride?
