Y'all ever think maybe it's because of the wide range of preference or belief of what pressures are right for a given tire/rig/condition? Can't even agree on it here with a bunch of "experts." IMO it's a lot personal preference. The people that don't care......don't care.
You gotta say what you want and then ask if it's a big deal. Just like y'all, I get weird responses when I say "No, I want xx psi in the front and xxpsi in the rear. My personal rigs don't get anyone checking air except me unless I get tires mounted. Company truck gets the jippo lube services where you gotta argue that yes I really do want 40psi in the back tires of my F250. I'm not carrying any weight this week and I like my teeth!
