Dan ! Your experience points out why not to use them (and certainly not try to fix them) Years ago on a fast downhill turn, a pal of mine proceeded to roll a tire and went straight off the road ,luckily a barbed wire cattle fence kept him from getting really hurt(not kidding) he was covered with cuts and raspberries but we stopped the next farmer and he got a ride back to town. Ever since then I have been very conciencious about tires on my bikes (and cars) I may over do it in stock piling tires but when I find some that are good (and usually not much money) I stock up.

RITA doesnt seem to mind 50 tires hanging in the
garage (now if I can only remember what I did with the other 20)
