That's a lot more air than I use but I'm in totally different terrain. For motocross I run between 11 psi to 17 psi. Riding trails I'm usually at the higher end up to maybe 20 psi max. In sand I'm at the opposite end around 11 psi.

It fishtails when you're going downhill in loose dirt? Then you probably aren't giving it gas, and the engine compression braking is strong enough that your rear wheel is sliding a wee bit, thus making it fishtail. As to tire pressure you are about 10-15 pounds overinflated-I run 15 psi almost all the time.
