Tire manufacture date

I really appreciate you trying to help me. I thought I was paying attention to what you posted, which is what brought me to the conclusion of 2 3/4 or 2 17/32 even 2 5/32 stud being what I would need. Each ones says it will work for Chevy’s...

Honestly, I don’t know which one will work, because they all seem to work.
I’ll start a thread if needed, maybe it will get more traction.
 
Two things you need to follow is the knurl size and its distance from the face of the stud. The knurl passes thru the rotor and is spaced out to fit in the hub flange.
DORMAN 98718.1 look this up on google and see the picture of the design of stud for the front wheel.
 
Ok I image searched and screen shot from dorman. I’m going to start a thread because I can’t find it. I searched droman last night for over 30min and screen shot what looked good. Another 30-45 this morning and still don’t see what I need... I do appreciate your help but I’m just not getting what replacement I need...

The first section out is the rotor area, next is the front hub area and the last is the thread area. The .625 is the knurl size required to hold the stud tight in hub. The distance out is .906.
 
I’m trying here but I still don’t see which one would replace what I have and would be longer....

ok, but when I searched dorman for “.625” i did not see a longer threaded portion for the lug nut.

I’m sorry but hahahahahah. Either it’s my cold or my me, I don’t see which is the correct longer one to buy. I put in “.625 knurl 9/16-18” and I get nothing for Chevy that is longer than 2 1/8 that is in there now
I’ll keep trying
 
I played this game when i convert to 2006 hummer fronts I ended up finding the length i needed. I had to use a stud with a larger knurl and re drilling the hubs. I have disk all around and was not limited to have the rotor behind the hub. Mine all slip on and knurl moved to the very back of the hub.
 
Ok, just got back from the test run and at 40psi they felt a little stiff, went down to 35 for now. Feels better. Lug nuts all re-torqued back to 110.. Pics are a little dark but you get the idea.

Took it to some woops and a dirt road and it handled great...now back and covered in dirt, feels good. That little amazon fan I bought works wonders blowing in my face to keep some dirt away...

35psi is likely still too high. That tire is rated for 3525lbs each. Let's say your truck weighs 5700lbs and it's split evenly front to back. That's 1425lbs on each corner, so your air pressure should be approximately 0.4x the max pressure shown on the sidewall. You can also mark them with chalk to help get the footprint flat. Many threads here on finding the right tire pressure. Just search.
 
Uh, I ain’t too good maff...
I try 30 next run around. Should more psi be up front because of engine and such lighter in back
 
I drove on dirt then pavement back home I can snap a pic of what the tires look like now after that?
This is at 40
I will try chalk across the tire and drive down th street

kids side walk chalk works good. the 1st pic I can tell tire are over filled, by pattern.
 
I'm thinking closer to 30psi, but 32 might help gas mileage. while driving around look at other trucks with big tires, you will see tons of them with the center tread smooth but the edges look new, these are over inflated. If the edges are worn but center is not, under inflated. No cut and dried answer when things are modified. I have military 37, on an old F250 rears are @ 20psi fronts are 28, all the time. My fiber glass dune buggy 7.00 15 front @ 5psi sometimes 0, and 265 75 r15 rears 10-12 off road 18 on highway. My burb I put D rated 285 75r 16 and I run 40psi on highway, no real off road time yet, few dirt roads. Got to put the time in to find the best for your rig and driving needs.
 
Yeah I spoke with @Bent77 and figured I’m pretty close at 35 but I’ll go down to 32 and see if anything happens differently with the chalk.

Should I run the same psi on all 4?

These are D rated tires at 3525 load capacity with 50psi the max.

Yeah, this 32psi stuff's for stock DD cars. Trust science not numbers stuck in your head. The bigger the tire, the lower your air should be.
