More bad news for me! Yay!
Turns out I have yet another tire that needs to be replaced, plus two sensors that need to be replaced. The reason for damage is still unknown to me.
I'm looking at $600 (2 tires, 2 sensors). I already spent $450 on the last two flats I got 4 and 6 months ago (all unrelated places and causes). I drive an old fiat model with a specific tire size that is just as costly as buying it elsewhere and shaving it down, so I don't have other options.
