I rotate at oil change, around 7-8,000 miles. Spare is stock so it's 4 tire rotation.
I drive to work on Wed, home from work on Sun-Mon.
One way is 4 miles rough dirt roads (20 mph max) & 18 miles highway (65 mph).
Summer reaches +120°f, winter is teens & the roads are mud.
So summer I run 37psi, heats up to 40psi. Winter I run 30psi.
