loss in tire pressure
is it normal to have a loss in tire pressure overnight? my tire went from 130 psi to 116 psi overnight, is this normal? or do i have a small leak?

That seems like a lot of pressure to lose overnight, I'd that your valve is closed properly and look for leaks

my guess is about normal. i go from 110 to about 80 over the course of a week. of course, i don't check it every day so i can't say how much pressure is lost over just one night.

when you first put air in temp goes up, so as pressure. As they cool to room temperature, which takes a minute or two, pressure will be lower. Also, over the course of a week or so, mine generally lose about 20/30 psi

Depends on the tube. Normal butyl tubes shouldn't lose that much pressure overnight. Me thinks there's some give from the method you're using to take tire pressure.

130 psi is a lot of pressure to hold. higher pressures will lose more quicker compared to lower pressures, so i don't really think that's all that much. 14 psi is nothing over 8-12 hours considering the pressure.
however, checking valves and checking for leaks are never bad things to do in your down time.
