Do NOT mindlessly pump to the "recommended" pressures on tire sidewall. It may be ok for vehicles but on bikes where total weight is usually largely dependent on YOUR weight, pump according to that. I'm 140 lbs and have it at 70/60 psi rear/front, and it's oh so comfortable on rough roads. There was an article that mentioned your tire should deform about 15% of it's height when on the rim and should serve as a good starting point.
