tire pressure

[Red Mist_imp]

I was going to mention also that I check my tire pressures before every ride, even if it's only been overnight. We can pick up a nail or staple or some other puncture that's not noticed and ride off on a seriously underinflated tire, and never know it until there's a problem on the road. A loss of pressure will alert us to the problem beforehand.

Sometimes a valve stem will leak after a new tire's been installed, or a rim will not properly seal. Air seeps out past the bead. It happens.
