I hear ya brother, and I was kinda conflicted on it, but finally reasoned some peace after a little whiskey one night LOL.
Initially I was all "I'd love to have a spare and be able to choose from all the awesome choices out today in regular (non run-flat) offerings". But honest story here - shortly after we got our TNG, I suffered a nail in the sidewall, and I can't convey how blessed and amazed and fortunate I was in being able to simply add a little air and drive her to the dealer the next day to get it fixed, no fuss no muss. We had happened to get the OE tire and wheel coverage added with the extended warranty, so it was a total freebee, but that's another topic ya'll probably don't want me flapping my jaws about LOL.
Also, I too was one of the souls that got the little MOPAR air inflator with the oil filter looking tire goop in our previous Scats, and it just kinda made me feel weird about the whole process and its potential temporary success for limping back vs calling a tow, and the potential dealer clean up on TPMS parts etc.(I trust no one to do anything right LOL). I mean, I was thankful to have it, but it seemed really weird.
Anyhoo, as we're getting older, my wife and I both agreed we're just gonna stick with and embrace the whole run-flat school of thought, especially since her ride has em too. In my mind, as a grown a$$ man I think it's a PITA at best and maybe disaster at worst when I encounter one. I don't even wanna think about my wife ever suffering one when out by herself. My only wish on that front is that more manufacturers start to come out with more A/S super performance run-flats in the DD TNG/392/HC size and specs. And it's not cause I dislike the OE Pirellis, but rather hope that a more competitive market might lower prices on em a bit.
