check out the Parnelli Jones (PJ) Dirt Grips. Nice tire and I believe they make a size to work with the H2. Tough to find though. Desert Rat carries them I think.
MT/R really are a nice well rounded tire though. They also fill out the wheel wells nicely and really add a touch of aggression to the trucks look. All this without rubbing.
