Dual tire pressure question
Before we departed on Mon for a trip I checked the tire pressure on all the tires. We have a 2013 2860 and according to docs the fronts are 65psi and the dualies are 80psi. I did the fronts to 66.5 and 65.5. The dualies I set at 79.6, 81, driver side, and 80.5 and 79,5 on the passenger side. When we reached our destination just for S&G's I checked the psi on all and got the following..67.4, 66.5, 83.4, 90.5, 84.1, and 91.7. Any idea why the inners have more psi..are they carrying more of the load?
