Mine were impossible to put on, I punctured three (3) tubes trying and scratched the hell out of my rims because I had crappy metal irons. But I got it figured out. By the way, these were the 23 SE's, which are "Tricomp" too, but maybe not the same model. The small etchings on my back tire wore off after a couple weeks, as I ride brakeless and skid occiasonally because I hate slowing down for lights.

So for your wear, it might be because of the 25's, and chances are they're blowing off because of the rims. These are really nice tires, and yeah, not the most skid proof, but they should last longer.
