I looked at hookworms, but they just looked too big and I'm not sure they would have enough clearance inside the swing arm. I've been using Ching Shen street tires. but I've had 2 of them go deformed, for lack of a better word, and was looking for something with a better casing for street use. What I really want is a 2 ply 2.125 street tire, but can't seem to find them, so thought I'd give the 2.30 panaracer a try. Got one on order.
