Sorry, but these stoopid nub questions will cease when I get more experience under my sitbones and picked your guys/guyettes' brains sumore...
Anyhoo, I checked the pressure in my tyres/tubes tonight... They were 105psi front and 115psi rear about 3 weeks ago... Tonight, they were 50psi front and 60psi rear...
Is it common or normal for the pressure to drop slowly from road tubes?
Yup....Exactly what you have is exactly what I would expect. I pump up at least once a week to a couple of psi over what I think is optimum for me. This gives me a week of riding, except for flats, before I usually have to worry about inflating again.

This is about right for 3 weeks, you should check pressure everytime you go out and ride. I use latex tubes and they lose about 5-10psi per night.
