The cold spec for my weight is between 50 & 55 so why would I over inflate to 65 or 75 per the vehicle label (noting the vehicle label is at 12,500) or 80 lbs on the tire.

Yes the tire heats up but everybody knows that and that is considered.

Fortunately tires don't fail easily even when we abuse them, but why abuse them? I got a lot invested in tires and want them to work properly and last.

I don't like to guess so I weighed my rig and looked up the right pressure.

By the way the spec for cold tire pressure is 68 F. One more spec hard to find is a bump for speed, add 5 lbs if running over 65 mph
