Tire pressure...
I think I was running mid-60s psi...
I really think the issue in my case is with the rear tire (and maybe my 220 lbs./riding style)--though, like I said earlier, the second torn sidewall seemed to happen from no impact whatsoever...no issues with the front (although I gave it away to a coworker after my experience)...
back on michelin mud2 tires which, for me, handle gravel as well as mud--which we've finally gotten here with a little snowfall last week...
