impep_whatever...Yes, the pressure will stiffen up the tubes by prestressing the steel. I think that high performance racing bicycles have pressurized frames. It permits the use of lighter tubing, and for those bikes every ounce counts.
By the way, use nitrogen. Nitrogen is a byproduct of oxygen production (they distil liquid air) so it is inherently a completely dry gas, and quite inexpensive because you get lots of it when you make liquid oxygen. Co2 would work also. The main thing is don't use air because the oxygen could cause corrosion.
