Only thing changed was the time of day? You gotta get a new tire gauge. That's where your problem is. [Reply]   [No Email]

Tire was very cold in the morning, and hot in the afternoon. I will check again in the morning, as I know the exact pressure now. Stan [Reply]  [No Email]

One wouldn't read anything under 90 PSI. The other would read 30 PSI at 40, and by the time the tire hit 80, it was reading about 54. The other two new gauges read within 2 PSI of every other gauge on the place at 80 PSI. Because it's new and high-dollar doesn't guarantee accuracy. [Reply]  [No Email]

You have to anticipate the heat build-up as you drive down the road. That's why the tire's rated pressure is "cold". If you have too much pressure it the tire when cold, it will probably build up too much pressure as it heats up while going down the road and blow out. [Reply]  [No Email]

What you see on your tire gauge is a pressure differential between the air in your tire and the outside air pressure. [Reply]  [No Email]
