Ok, The tag in my door on my truck says 65psi on the front tires and 75psi on the back. The tire itself says max cold psi @80.

Where should I keep them? My guess would be put them all to 80psi when Hauling heavy load and follow the door when I am just doing daily driving.

I don't really claim to know much, so what do you guys do.

Thanks,

Josh
