Tire pressure when hot kind of high

Would love to see a link to any tire manufacturer's site showing that.


Like many, I have "read that on the Internet...... so it must be true......" Well, maybe not.

Tire pressure change based on elevation is basically noise level. Maybe 3-4 PSI lower in Phoenix than Santa Fe.

Temperature DOES have a significant impact on tire pressure. Far, far more than elevation-- roughly 2% change in tire pressure for every 10 degrees F (higher temperature= higher tire pressure).

Why did you go to 80 PSI, cause you can? Read the sticker on the door for max pressure with max payload.....
