Suddenly I can agree with about half of what you posted above. There is still too much
the OP hasn't told us, and we are all assuming. More info about the truck and tires would
help a great deal. Until then...

Very true, 1/2 ton, 3/4 ton, LT or P rated. All determine what they should be.

If they*re standard equipment then as mentioned already, check the tires and door jamb. I was under the impression they weren*t standard equipment.

Call the builder

Call the tire shop and ask them how much powder you should load in your ammo.

^ This.

When the weather is better do a "chalk test". Pick up a small box of sidewalk chalk
and use one of them to make a wide chalk mark a couple feet in front of each tire.
Then drive the truck over the chalk and try to get the chalk on the tire so that you can
see where the tire picked up the chalk, it should be on the tread from edge to edge.

Adjust pressure accordingly.

The max pressure on the sidewall of the tire is based on the max load range for the tire,
but the PSI seen on the door jamb sticker is for your vehicle's weight and GVWR.

This is interesting, I have heard of the chalk test being done differently, as follows: rub chalk directly on the tread of the tire across the entire tread then drive one or two revolutions of the tire and inspect. If the chalk is worn off the centerline of the tread this indicates overinflation, worn of the inside and outside edges, indicates under inflation, worn evenly indicates proper inflation. Now Im going to have to grab some of the daughter's chalk and see which method works the best!

Any truck/auto experts out there? I bought a new Chevy Silverado Black Widow a few months ago. Has all the upgrades and 35 tires.
Got a screw in one tire today and brought it back to dealer to fix.
After fixing, they noted my tires had standard 32 ish psi.
They said, "these tires need 70 psi" and put that in them.
I asked, Black Widow built this truck, and delivered with 32 psi, wouldn't they have known that?
They said not sure, but they need 70 psi.
I am obviously not an auto expert - does this sound right?
I'm relying on my gun expert friends for this one - lol
Thanks!

What does the tire pressure sticker on the inside of the driver's door frame say?

They aren't tires (size) that were meant for the truck, so that sticker isn't really relevant.

They may have updated that if it*s standard equipment so it may be on there. More info from the OP would help lol.

Shouldn*t this question be in the inflation thread?
