Mostly sand, some jumps, and trails, but sometimes thick mud gets in the way. What pressure r u running? Do they really hook up better in the sand running them backwards? What does that do for the mud traction? Which way do you run the tread?

dont run them backwards, they are designed to run the right way.
it should say what way to put them on. I am not very sure about the tire pressure though.

Yeah, I mounted them the way they said to. How much pressure? It says 7lbs, but on this one, I have to deviate. At 7psi they are hard as a rock.

I run about 5.5 to 6 PSI in the Wetlands I have (which btw are radials). I know they're not the same tire as the Bearclaws, but they also say to run 7 PSI. It won't hurt to lower the PSI on your tires a bit. Try starting at 5 PSI. I wouldn't run any lower than 4 though (could run the risk of bent rims the lower you go), but just experiment and see which works best for you.
