Check around. My shop still sells them for similar to before. Maybe $10/tire more.
They also have the new Vorti tire that is a little more money, but still less than the PSS.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
