I wouldn't... a lot of tires will blow off the rim if you go much above their rated pressure. Get tires with a higher rated pressure instead and be happy. My touring bike has 700 X 32c tires and I inflate them to the max of 85 lbs and they feel pretty good under my 260 lb carcass. Tires are available in all sorts of widths and pressure ranges.
