I'm too lazy to change pressure so I just keep it where it is 8-10lb and they wear forever no problems but hey I'm not knee dragging either .

Really nasty stuff I will gather my forces and drop to 6lb and for connecting pavement I have no problems leaving it at that.

MT21 front, hating pavement?
It's about the most pavement friendly of the knobbly fronts.

I've got an MT43 front on the way. I'll either hate it or it'll match my riding style well.
Can't wait to find out.

What do you think of the MT43 front? I just installed MT43's on the front and rear but won't be able to ride for a few days (Colorado Rockies). This will be my first time riding on trials tires.

Lots of folks use the MT-43 rear, but as you know, few seem to use it on the front. Crawdaddy likes the front. You can Google his posts; here is one:

From what I read, most folks run 8-12 lbs. I am working myself up to trying a rear on my WRR, probably with MT-21 front. Wish it wasn't so large though. Messes with the gearing, and besides, the WRR is already tall for me

I like it on the front. Did 3hrs today and the rear let me down more

Very good under brakes on anything non-muddy.

I don't go fast so there's no leaning it over and nailing it through corners.

I Was on the fence for some time about the MT43 on the rear. However I have now mounted the MT21 on both ends. Seem to be working well if you keep the pressure 15lbs of so.
I will someday get a MT43 for the rear to see what all the HooRah'n about !

I'm trying to follow this discussion and one like it on another thread. Please check my distinctions here, because this is the only way it makes sense to me:

The MT-43 is a HYBRID tire: very stiff sidewall with a trials tread. Hence it works well on the road, and on rock, and on sticky soils, but less well on sand (?) and in deep mud. Low pressure off-road for traction; higher pressure on-road to mitigate heat build-up and provide excellent longevity. So, you need a pump.

The MT-43 is more likely to be loved by trials riders and (usually) hated by moto-cross and competition enduro riders, especially on the front. The racers put too much stress on the front and it washes out. Trials riders are going at a much slower pace and this allows the front to exert its grip rather than be pushed laterally.

Hence, dual sport riders are expected to like the MT-43 front if they are on single track and are riding at a moderate pace. On a WRR or DR, for example, they will shine at lower speeds. And almost anything will work on two-track and dirt / gravel roads.

At the same time, current and former race riders who are riding the new race-based "dual sports" (e.g. KTM 350/500's, Bergs, Huskies) are less likely to be fond of the MT-43 front as they are used to riding faster and want to take advantage of their cutting-edge hardware. They tend to ride past the front tire's limits.

And there are some surfaces that are just not MT-43 friendly, but the MT-43 is a lot more friendly to the trails than a knobbie.

So, it is not really all about terrain, but about riding style, too.

Does this sound right?

I ride a WR250R. I have the 43 on the back. Riding yesterday in muddy hilly terrain. Putting a 43 on the front in those conditions would have been a truly religious experience...front brake is better than no brake. I would never go with both where I ride.

Yep. if you're going to lean the bike over and give it a handful then trials tyres aren't for you.

Met a guy on a KTM300 on Sunday. MT43 rear and knobblie front. The MT43 had been on since December and was half worn. He runs 4psi and doesn't race, but loves the trials rears as they get him to where he wants to go with less fuss than with knobblies and they last a lot longer.

Trials fronts are only really an advantage going slowly down non-slippery stuff under brakes. It's more sure footed than a full knob.

I go slowly down stuff so it suits me
