Unless you patch the tire with a patch that has real strength. I've patched many tires with dacron sailcloth (not the"sailcloth" you can get at fabric stores, the real stuff; scraps from a sailmaker). I cut the patch oversized then glue it in with contractor's contact cement (with its toxic fumes; the stuff for countertops). I've put a thousandmiles on cuts nearing an inch. The tires died from natural causes.
