Its amazing you were able to cause that much damage with 30psi in the tires....
Not a lot you can do to fix that other than getting a set of steel wheels OR getting a tire that has a larger rim protector. Some of the more aggressive tread designs have a much thicker section of rubber around the wheel lip.
I'm going to guess you didn't air down enough or hit the rock to hard/fast. If you air down to about 12PSI the tire becomes twice as wide as the rim. This creates a barrier so the rim should of had rubber between it and the rock. Look at my video here fast forward to 1:26 this is aired down to 15-17 PSI I think it was but you can see how much the tire mushrooms out protecting the rim from the rock.
The first time I did this, I wasn't sure if speed might have been an issue. i wasn't going very fast, but I was moving. This last time, I know exactly where and when it happened. There was only one rock, about twice the size of a basketball, but shapped like a footbal. It had a scuff mark on a small sharp spot (the pointy end of the football) from the impact with the rim.
Sal - I watched your video and I see what you are talking about. My circumstances were a little different. This was the front tire, and it was turned all the way to side at the time. I am speculating this sideways force is what pulls the tire sidewall over enough to expose the rim. I wonder if airing down more as you suggest would make that pulling sideways of the rubber off center from the rim worse, or better? My thought was a stiffer tire (more psi) should stay more true to form right over the rim.
