Trials tires in sloppy weather???

[Boom Boom]

I run the MT-43 (non radial and DOT legal).
In rocks and running fast 10psi works well.
Drop to 8psi if a little sloppy and running slower pace.
If traction is the main issue I will run 6psi.
This is using a HD tube and one wheel lock on a 450 Berg.
Have not spun the tire on the rim yet.
If running a radial trials tire then the tublis system would be the ticket so you could air down even more and take full advantage of being a radial tire.
I run a modest amount of road at times and have turned the knobs on a radial trials tire to mush when running at speed.
IMHO the MT-43 offers the best of both worlds at a reasonable cost and lasts forever. If running 100% off road then the radial can have advantages.
Nice tips about cutting rows out for better mud removal.
I do not remove the entire knob, but use a small router with the bit set at 1/4" and lower knobs on a stager pattern. Anything to offer a small amount more bite helps in slop conditions. Also, when my knobs start to round I will make a cut back about 1/4" into the rounded face with sharp knife and just let the flap of rubber hang, it tears off to the fresh cut face in time riding.

I also use a MT43 with a heavy duty tube. I run 7 to 8 lbs. air pressure and use blacktop and fire roads to connect trails. Speed limits are 25 to 35 mph. I am amazed how much easier it is to get up and over tricky exposed roots with this tire!
When I can come up with the funds I will start using the TuBliss also. Less worries and less air pressure, and easier to install.

Another MT43 here as well.

I have run a MT43 for 3 seasons now and have also run a X-11 and 803 for comparison.

The reason I chose the MT43 is because it is more versatile than the other 2.

Having a stiffer sidewall allows you to ride in a more traditional manner and you can brakeslide without rolling the tire in the corners. Yet, it still gets amazing traction. It may not be quite as grippy as the other 2, but it is close and for me, the ability to treat it like a knobby in faster terrain is a huge advantage.

I now run one with a Tubliss and this makes it even more versatile. In muddy conditions I can run it down to 5-6 lbs. and it will hook up unbelievably. The Tubliss allows me to tune the tire pressure to conditions and when I know I am needing hook up and wont be railing, I can run it at 5-7 lbs with no fear. When it is higher speeds I can simply run 8-10.

The one thing I notice is that if conditions are thick, sticky mud, the trails tire becomes ineffective because it clogs and you lose it's ability to grip. But, in those tough conditions, no tire works well. I have run my MT43 in these conditions with friends with knobbies and they faired no better.

I will never go back to a knobby and will even keep the MT43 on when I do a few GP track rides.
