I can't stand it anymroe and have to chime in.
Guys! I would not use something like a Dynaplug. There is a reason why the speed rating drops to only 90mph. These type of plugs have very little preventing them from working their way out. I use the cord plug, which makes a loop inside the tire, thus preventing it from working its way out. Ditto for actual patches. Both have something inside the tire that causes HUGE resistance to pulling out.
I am perplexed by guys who know apparently little about tire patching, passing kudos on this type of plug. It is no different from the inferior rubber plugs, that work their way out. Yes, it comes in a nice compact stainless or aluminum holder, and looks high tech. That is where it ends!
You use a Dyna too small, and you got serious problem. Nothing holding it in except the goo on the cord. Not risking my life with these.
It costs stupid money for what you do not get.
One other thing. Website says it does not need rasping, blah, blah. So why does the kit include a rasp probe?
Look, I have been using plug lits for 40 years, and have lots of experience with them. I highly recommend the Black Jack plugging system, especially for speed rated tires like ours.
