Plugs for radial tires is ridiculous and dangerous. A radial must be plug patched and performed with proper procedures or it can fail as well. If done properly they will hold up. The tire should only have one plug patch or it should be replaced. I know people who do other things and sometimes get away with it. Most tire shops and dealer will NOT patch high performance tires because of liability issues Here is a picture of the correct patch to use.
