Hmmm... I use much lower pressures all around on BFG 230 compound tires, 
like 22-24 psi. Oh, and you can take the pressure down to about 5 psi before 
the tires start looking low. I tried it with my previous worn-out set. Of 
course you shouldn't do this with tires you're going to be driving on; 
pressures that low can disturb the seating of the bead on the rim. I did it 
at the place I got my new tires mounted, because the guys there were also 
curious. We then took that rim off the car and mounted a new tire.
