What do you actually check on a pre-trip inspection?

I almost prefer a framing hammer, if I’ve been running the same rig for a couple of weeks I can find ones 20# low. (Ie, they are all 100psi I have found them at 80)
I can’t get quite as accurate with a 2#er. I’ve never been able to use a tire thumper for anything other than flat that I could already see.

 

I had a good "school" when I lost my first trailer's axle due to hubs being "dry" since I bought it few thousand miles back, literally dry and not knowing that I had to check the hubs not just for oil leaks, but for oil presence as well .

 

My last truck and trailer I could tell when they're down to 80.

This current rig I'm driving is very hard to tell. The superwides on the trailer are even harder. I'm looking for bulging quite often when I'm loaded.
