I used a Dunlop on my 250 but pulled it off when I sold it and bought a 125. I’m going to give it a try on the 125 this weekend and if it works on the small bore I will probably buy a new trials tire since the Dunlop is fairly worn. I am interested in the MT43 for the stiffer sidewall. I am not sure how a bias ply will work though. I think most of us assume a trials tire works well because it is radial but maybe it is the closely spaced soft rubber that is important? With the Dunlop I would have to drop below 8psi in clay. Then the tire would flex enough to clean the mud out. With a stiffer bias ply tire will it flex enough to clean out? Eric K loves the Mitas, he rides the same terrain as me, and he has tried most of the trials tires. Normally this would be enough to make me pick it but most everyone else does not like this tire so I am not sure about it. It is another option though. Otherwise I will probably get an X-11. Most of what I ride is loamy mud or greasy clay with lots of roots and rocks thrown in. I don’t get over 30mph too often on our trails.
