Tires are very chopped after just 30k miles

I believe you have your indicators backwards.

 

Shocks have a year and roughly 25k miles on them. Truck has 34k currently. I wouldn't think anything would be too terribly worn out in 25k miles with the tires and suspension installed. Icons are only giving about 1.5 of lift, there shouldn't be much added stress on the ball joints. No wandering, it has always tracked straight.

 

I did this and ended up with about 27psi. The way it was explained to me is the car manufacturer recommends a tire psi based on the volume of air needed to support the vehicle weight. Following that logic as you get a bigger tire you'll need less pressure to get the same volume of air. So far it's worked out great for me. Very even tire wear and good longevity out of them. Like I said before I got ~53k miles out of my last set of falken wildpeak MT and I'm set to get about the same mileage out of this next set.

 

It got cold here in the south last week. My tps on my JLU went from my normal 37 down to 33 on all 4. On my evic it shows all at 33 in red except the passenger front is white. Any ideas?
