Mech: The tires are Specialized Cross Baldies. I like the tread -- nice semi-slick with good cornering knobs -- and the fact that I can air them up to 100 psi. They're great on dry hard surfaces, but a little squidgy in the muck and skittish in sharp turns. I've noticed that the Kenda Kwiks have almost the exact same tread, though they max at 85 psi. I might try them.
My mud/wet tires are Michelin Cyclocross Mud and Sprint.
Cadd: The bike is a 2001 Kona Major Jake. In fact, 2001 was the only year of the Major Jake... all the other years since 1998 have only had Jake the Snakes.
