My opinion is...
I run my tires 5# over the recommended inflation for my weight. Now unless my motorhome is pushing going into the turn and I need to add half a pound to the right rear to stop this (of course its much worst at Talladega Superspeedway turn 4) at 180mph I don't really think much about my air gauge reading plus or minus a couple pounds. I use the same one as DriVer.
Hope everyone has a safe Memorial Day weekend and lets not forget the significance of this holiday.
