Getting ready to head out tomorrow and put new tires on last year. This is our first trip for the summer (yeah I know we're late in the game). We don't recall what psi we had at last year. Tire said 80psi cold. This is on a small popup. Seems pretty high, our regular tire gauges only go up to 50, so we may need to go get a new gauge. Called the tire place and asked if we really should inflate to 80psi. They said no, that is cold psi. They would not even inflate to 50, as they said with hot weather and also road friction will increase temperature. What is everyone's thoughts? Current temperate is upper 80's outside. From searching the forums people do say that they should inflate to what the tire would say, but any thoughts on the outside temp and road friction? Thank you!
