Setting tire pressure before hitting the road
Getting ready to hit the road and want to set tire pressure on truck and trailer. Max load pressure on 5th wheel is 110 lb. I set tire pressure cold but should it be set first thing in morning or late...

Do as the truckers do, hit the tire with a hammer. If it sounds ok , it is.
In point of fact, the trucker's are listening to see if all the tires sound the same. If one sounds different, then it's time to get out the tire gauge and see what's going on with it. They do it this way because it's a LOT faster than breaking out a tire gauge and actually checking each tire. And it also is based on the belief that all their other tires are correct.
If all the tires are wrong, then all the tires will sound the same and the tire thumping doesn't tell you anything.
Of course, these days, with TPMS systems, tire thumping is going the way of the buggy whip even among truckers. Eventually, it will be a completely lost art . . .
