Call me picky. Call me detail oriented. Either way, I hate it when my drive axle has 4 different psi readings. Even if off by 1 psi, its annoying.
This is even more important with the steer axle.
I finally came up with a solution.
I am using my viaair, specially made manifolds, 300 psi 1/4ID air hose. I can now air all 6 tires at the same time and ensure perfectly matched pressure!
Same setup works on the front axle too, as the chucks I am using are sealed unless connected.
During my test all 6 tires where 80psi. Needed to add 10psi. It took 15 minutes of just waiting for the viair to do its job. Not too shabby.
