I fell down the rabbit hole that is 550.com tonight and look what I found:
its been a while while so I can't remember if that's an X or an XZX, but Coker sells those and IIRC, they're significantly cheaper than the Sprint Classics and the Cinturatos. (At least they were the last time I looked)
And, if they're similar to the originals, you'll never have to buy tires again.
