Exactly my thoughts. How do I know how accurate my gauge is? Probably close enough.
If I were going for the world hour record on a track I would worry. Riding to the next town with a bunch of 70-year-old for cake and coffee, not so much. As long as I don't get a flat.
That said, I run Conti 5000 tires at about 90psi. Or so my pump says.
