Most of the chain or franchised tire stores will tell you that plugging tires is not safe or a permanite repair. This is simply not true and just a way to dig a little deeper in you billfold. I have been plugging tires for years without any issue, as long as it is a punctured and not cut and in the tread not the sidewalk. I strongly recommend going online and purchasing a TIRE REPAIR SEAL KIT (pic below). It won’t hurt or injure your hand and there is a guard on the needle so the plug won’t push all the way through. Inflate the tire to around 20 psi over normal and use brown plugs or black plugs are okay.
