Crappy tire wear + reccomendations

So for a 8 foot bed, and diesel puts that much more weight on the front end. DAMN.
I can understand it being a bit more with more rake on your truck than mine because mine is almost level. But didn't think it could be that much.

I have auto level, so the rake adds minimal weight to the front. Even a standard suspension won’t add much from rake.

Mine is 1” different in normal height and dead level in alternate ride height.

Would be interesting to see if there is any difference on the scale someday.

I run 35 to 37 hot on the front and 30 to 32 hot on the rear to give me the best wear. I didn't buy a HD truck for the fuel economy. :cool:

Again, hot psi isn’t the important number. Hot psi can vary way too much to utilize for proper fill. Fill it to a good stable cold psi that’s appropriate and seal with the hot pressure.

We run 40" BFGs on the race truck. Start at 27 cold. Will see anywhere from 35 to 45 hot after about 200 miles of racing offroad. All depends on the terrain and speed. That's a 6K lbs race ready truck.

That’s a lot of tire!

Yes they weigh that much. My truck new with just me in it was 5,260. That was with 3/4 tank of fuel and not even spare napkins in the glove box. Now it's well over 5,300lbs "empty"

Published base weight for the OP's trucks is 4,996 lbs. That's a base model without a driver or any payload/passengers.

Your truck is also a short box which according to the Ram charts is 158lbs lighter on the front axle than a long box of the same configuration. The DRW's are another 28lb heavier.

25 psi on a 35x12.50R17 is only rated to hold 3,750 lbs, so you need 30 psi minimum for your 4,280 baed on the charts.

60 psi is insufficient on a 235/80R17 as that's only enough air for 5,030 lbs. 65 psi is the bare minimum as that's rated to support 5,360 lbs.

Up to temp pressure is not what matters, only cold inflation pressure.

I have not personally seen a 1 or 2 mpg loss from running the proper pressure on a HD truck. I have noticed that much on smaller rigs. Your rolling resistance is a little higher, but hardly measurable IME on a HD truck. It really starts to impact economy when underinflated.

Not to beat a dead post to death, but now I am curious to find a scale to weight this truck. The door sticker says the payload is 4885 lbs, which on a 14k GVWR is 9115 lbs. It is a Laramie CCLB, air suspension, 4wd, 50 gal tank etc so some bells and whistles. It's amazing how much more this all adds (hell 50 gallons of diesel weights about 400 lbs)
 
Also update, getting Kuhmo Crugen HT51s with the hotboi alignment yall reccomended. If i need to go offroading ill just slap some chains on em.

My truck is very similar, aside from being a SRW.

Lots of weigh stations are left on when closed and you can weigh yourself for free.

9115 is on the higher side, did your truck come with the 5th wheel hitch?

Yes, the Mopar 30k hitch which is 200 lbs or so.

Thuren alignment spec is what you need.
Made a significant improvement in steering tire wear on my 2022 DRW. These trucks come from the factory with too much toe-in and it murders the outer edges. You’ll still get edge wear, but significantly less with the Thuren specs.
Thuren Fabrication Alignment Specs

I assume those alignment specs will work on the 23’s? Bout to go on a long trip and would like to minimize the outer edge wear on the fronts.
 
Final update, I had 0.3 degrees of toe in on the worn out tire. That would do it.
