Yeah. From what I've read they don't do well on pavement unless you pump them up. Not sure how long they last..........
just checked, they wont work for me. I occasionally ride on asphalt.

Seems like the heat is the killer!

IRC - do not even consider running this tire. Good straight line traction, but its too soft and wallows in the turns. I could not get comfortable on this one.
dunlop 803 - pretty darn good tire. I would run it at 8-9lbs. Any more than that, and its less effective. Take it easy braking. On silt, it will lock really easily making your rear brake rather useless. If its not locking up and sliding, then its digging in and stalling the engine. Excellent play ride tire. Will last darn near forever. Works really good in sand and loose stuff. you can air it down to 6lbs and there won't be a hill you can't tractor up slowly.
Pirelli MT43. Dot approved and works well on asphalt. Not quite as much traction as the dunlop, but it feels real good turning. I run mine at 9lbs. This one tends to lockup easily on downhills, which scares the shit out of me. I've raced this one and felt pretty comfortable with it cause it feels the most like a knobbie when you turn.
the dunlop and pirelli's are great tires

I tried a trials tyre on the rear of my '08 WR450F for a few months until a few rides ago.
As stated elsewhere, the grip is amazing. In rock, loam, sand (yes, sand), medium mud, etc. I never tried in thick mud so i can't comment there.
Unlike a knobby it retained almost all of it's original level of grip even when the knobs became rounded on their leading edges.
The downside is that to achieve that level of grip you need to run quite low pressure (8-11psi) which makes the rear of the bike very "all over the place" at speed when cornering.
You can feel the tyre rolling sideways on the rim. I didn't like that.
I've now gone back to a knobby.
I still have the trials tyre in the shed, I could easliy put it back on (reversed) and do it all again anytime.
I sit on the fence with trials tyres on enduro bikes.
Give it a try!

Soften up the surface with dirt, sand, loam mix...it looses it's edge over the knobby. However, my 06 KTM 300XC is fantastic with the trials tire up here in the PacNW area where it's predominately rock content. And I've been amazed at how well the tire hooks up in the softer surfaces with more dirt content. There's no way I'd go back to a knobby up here. But down south in OK, TX...now that's another story.
