@Ragman,
Okay, some good guidance offered here. I see a pretty balanced split of recommendations which advocate taking a course of "don't bother" and "self-repair" is
maybe okay.
I think my predisposition toward [trying to] repair things that break originates from childhood, since my dad was an engineer, and he always encouraged us (his sons), that if something is broken, be willing to take it apart (and fix it yourself), since most modern devices are not hugely complicated (if they were . . . a refrigerator would cost $10K). On top of that, his first "gig" out of college was working as an engineer for U.S. Rubber Company (forerunner to Uniroyal and then Michelin) - so he has (or had) "rubber in his veins" at some point, and based on his knowledge of tire construction, he always encouraged most (but not
all) tire repair, for simple punctures - since the evolution of tire construction has taken us
well beyond the days of catastrophic tire failures (and no comments about "the nut doesn't fall far from the tree", if you please ).
So, I've been driving for more than 40 years, and have been repairing (repairable) tires for more than 30 years, and yes - it takes me about 10 minutes and costs me about a $1 to repair it myself (that actually sounds reasonable now that I say it . . .), and this is the
first time a repair attempt has not worked (or has ever failed after being repaired). So, for
Ragman, I'm not sure I've made this more complicated, since it was something I was willing (and maybe able to do) - and so, I've maybe only saved $600 - $1200 over that 30 year period, but it has worked for me.
Bottom line, while I could spend $90 and buy a new tire, and toss out a (not-perfectly) good tire - I think I'll take the repair-inclined advice and default to buying and using the more tire-appropriate
automotive tire repair patch - which I did know existed (but I already had the bike tire kit). A good, balanced discussion. Thanks!
