Will be starting my second build soon, and picked up a Huffy Warhawk to use for parts. The 29" x 3" tires have a knobby tread and I have been looking for tires better suited for pavement. I saw the Maxxis Hookworm mentioned here somewhere and they make a 29" x 2.5" tire which should work fine, but they are listed as "Single ply 60 tpi casing." I don't know much about this, so I'm hoping for some guidance here. Thanks for any help and suggestions.
