Can't be any more narrow than 2.0 and has to work well in a variety of conditions, but most of all sandy hardpack. I've tried the Hutchinson Python UST and didn't like them. Not wide or aggressive enough for my tastes. I've tried the Panaracer Trailblaster which was a wretched tire for practically all terrain, but rolled fast. Tried the Michelin XLS and Front S combination and am currently running that. Good traction, but I'd like better cornering and lower rolling resistance if possible. I also tried the Michelin Jet S which is an amazing XC tire for hardpack conditions but doesn't offer enough bite in the loose/root filled sections. So what are my options here? I don't want anything narrow, obviously, and rolling resistance isn't too much of an issue, but I don't want anything that won't roll worth a damn either. Basically I want something that will offer lots of control especially in the corners. Any suggestions? It's gotta be tubeless which narrows the selections immensely.
