@Karstan Yeah, they don't even have any estimates that I can find. But I'm currently going through a rear tire every ~year and a front tire (that I'm sort of pushing it) ~2 years. And I'm buying tires that run in the $70 range when I can't find them on sale. I think my price point is going to be "is it less than $200 each". Which seems like a lot, until I do the math on my current tire usage. Also the no flats thing.
