I don't buy that contact patch argument, last night I went from 2 back to back bad 60' times (2.671 and 2.405)with 33lbs in the rears to consistent 2.20's with 25psi. The difference in contact patch between 25# and 35# is a couple of mm, big deal. The difference in friction is quite a bit different. It is not unsafe to run 25lbs of air pressure.
