My current setup -2006 TB 4.2L 4x4 -305/65/17 -34 psi all around -load range E
But I would rather have c for the extra sidewall flex. I do like how tough mine are though. You got a tough decision. Just remember some tires only come in certain load ratings.
I hate to advocate weird chemicals, alcohol, violence or insanity to anyone...but they've always worked for me.
My current setup: -2002 TB 4.2L 4x4 -265/75/16 -35 psi -load range D
More flex than an E rated, but more durable than a C rated. E rated also creates a lot more rolling resistance because of weight. Harder on the brakes and the gas tank.

I like the sidewall flex, but constantly worry about tearing them. No problems so far though, and I've been driving through a lot of brush recently (overgrowth on old, unused trails).
