ok, I can research tires till im blue in the face, but I need some suggestions. Not for my hybrid, but for my MTB that I ride on the fine crushed gravel of the NYS erie canal trailway. 26" wheels. I have Panaracer Fire XC pro on right now, LOVE those tires, but need something less aggressive, but still with some tread on them. This year I am going to make it my objective to ride the canal trail every single weekend (that it doesnt rain). 30-40 miles per weekend (in one day). Price is really not much of a concern, but I would appreciate less than $30/tire. Something that is going to last. I dont do much offroad, but still want some knobbies. I would prefer a 1.8 width or smaller, so I could mount fenders (that dust from the gravel makes a mess...) I want something that will provide with the same durability the fire xc pros have, ZERO flats in the hundreds if not thousands of miles they have seen, on/off and inbetween road.
