Kraig,
 It's not just a single, thin tread of tire creating the erosion. You know 
as well as I do that there is an awful lot braking and sliding on rapid 
descents. That causes major erosion! And then there is just the attendant 
lack of concern for this effect when you know it is happening but you want 
to preserve your rights. I went mountain biking in the Lagunas one time and 
felt pretty bad knowing how much erosion that one descent caused. Never 
again in a semi-pristine area. I don't care if it is allowed, I won't do 
it-- it scars the landscape. Land boarding, too. Don't get me started with 
that...
