Looks like Idaho also has fairly low tax rates. Running out of states to retire to - TX and ID. I am worried about TX drifting blue.
Sucks, always dreamed about retiring to CO. Guess with CU Boulder out-of-state tuition I may not even get to retire at this point!

Back on topic - made the drive today Boulder to KC. Dropped air pressure to 40/38 before I left Boulder. Much better.

Pressure when I got home (cold) dropped 2-3 lbs per tire from Boulder to KC.

Eastern CO I-70 still like a washboard around mile marker 430. Pinkish highway…

I like to go lower pressure than that and it helps. I run somewhere in the neighborhood of 35/33 unloaded around town. I'm kinda lazy, so when the seasons change that goes up or down a pound or so and I ignore it. The roads in Colorado suck. We spend all of our transportation money on bike lanes, fancy buses that few ride, light rail that runs at a loss, and new curbs. Actual new pavement is vanishingly rare.

Yeah, my dealer is making me crazy with tire pressure. I have always run about 36 all four tires. When I go in for “the works” it always comes back in the 40s. This time I forgot to adjust it back - oops. Truck was bouncing all over the place on those washboard roads.

They always set mine to 40 as well. Feels like they broke something every time. I drop them to 38f/35r as soon as I get home

40psi must be the spec. I just got my truck back from “the works” and all four tires spot on 40psi each.

40 warm would be about 38 cold, which is the spec. When you're at GVWR. If you're unloaded, 38 cold is too high.
They set mine to 40 cold. It was 35 degrees that day and I live less than a half mile from the dealership. Didn’t exceed 35 on the way home.
