I have used it in very wet conditions! Man, that's all we have had for the last few months. This is the best tire I've ever used, period.
I CAN'T BELIEVE YOU ONLY TRIED THE REAR!!!!!!!

Dude, the MX 31 front is even more impressive than the rear. Run it at 6 psi, you'll never use another tire. The conditions here are just flat gnarly. We have sloppy mud, we have hawaiian ice (wet red clay with monkey snot on top), imbedded rocks, of course, slick logs. I also have tried it in the desert with equal results, though our desert has lava rock amongst the sand and is hard on soft terrain tires because the knobs are so far apart that they tend to tear. The MX 31 held up much better than S12's have.
