Torker LX Tire Clearance

I just got a trials uni and want to use my old 24" LX for light muni at my local cross country trails, but want a tired that is a bit beefier to absorb roots and such. Has anyone here ever put an wider tired on a 24" Torker Unistar LX? If so, what kind of tired was it, where did you get it, and how much was it.
