Kenda Nevegal Lite 1.95 Stick-E's UST's!!! IMO, best tire out there right now! Actually, the Nevegal is the best tire out there period (in any size)! I run them on all my bikes. The 1.95's on my HT, the 2.35's on my Kona, and 2.5's on my DH bike!
Of course they're one of my sponsors so I might be a wee bit biased...
