My question; Is it safe to patch (vulcanize from inside) or put a tube in? These are near new Metzlers and the punctures are very small and clean. I don't want to shell out for two new tires if I don't have to but, I also don't want to put my Sweetie in any danger. I have a tire plugger but, I've seen threads that indicate you shouldn't run a plugged tire for longer than necessary to get it replaced.
The many variables are what really makes the answer more confusing and is why most dealers will not repair.
If I discovered a nail in the tread area and the tire was still FULL OF AIR, I’d be inclined to do the inside patch/plug repair although I would not let my wife drive with that tire (I’d put it on my bike if possible). If the tire was driven with low pressure (sometimes evident from running on the sidewall) the excess heat and flexing MAY have caused delaminating of the plies that may cause a problem early, late, or never.
A good case can be made that simply breaking the bead and tire removal from the rim is cause for concern if not done correctly.
The gummed fibrous push thru plugs are only temporary, air could seep between the plies allowing internal breakdown. As stated earlier, you’re dealing with two tires not four. And IMO the rear tire represents less risk than the front.
So as you can see it is tough to have a single answer to a very serious safety issue.
BTW, are there any tire experts that could comment on the use of a tube as they use in spoke rims?
