Definitely not.

On my road bike, the front tire loses about 10 psi overnight after pumping to 100, and the back tire only about 3-4 psi (same starting point). The front tire's tube seems to have a problem with it.

Even if I pump them to 110, it's pretty much the same result after a day or two.

I am not heavy (120 lbs) but I just can't ride my road bike on tires with pressure under 90 psi. It's pretty around here and tire pressure makes a world of difference.
