the moto diggars are a pretty good tire, expecially for the front! Mine last just over a year (still has grip, but i have just worn a gole in the side from dropout tricks ) For the back I a maxxis swampthing 2.5, which is probably the best tire choice for trials, there are some other good more streety tire out there, if you wanna go that route (tioga comp x) the bike looks pretty decent and its looks like you have it set up well too.
