In general if it's just trail riding/mud riding through the woods, you're looking for a psi for comfort. Depending on the tire, and on a non beadlock wheel, anything from 14 - 20 is a good, safe area to be in (the higher the load range of the tire, the lower in that area you should be). There will be a point in airing down where your tire goes from "looking a little low on air" to "looking flat". There is no reason to be low enough in psi to "look flat" when just trail riding.

In general, for rocks, you want to be as low as possible within reason of the tire and wheel combo. For most people with "fancy" cast or aluminum wheels and radial offroad tires, that number will never go below 12. Anything below that really seems to be a game of "when will you debead, not if". At that psi level, you can get a soft tire, like a KM2, to completely fold over on itself while still staying on the wheel. For a stiffer tire, like a Trail Grappler, it will take a lower psi to create the same fold but that probably wont be enough psi to hold the bead. Keeping the tire on the wheel becomes the more important thing here. Once again, you will reach a point where the tire "looks flat". This is fine for rocks as you want the tire to wrap around them as much as possible but you will also reach a point of diminishing returns. Your tire will only wrap around a rock so much. Once its low enough to fold over on itself, mission accomplished. There's no reason to run lower psi than that. You will also start to lose a considerable amount of ground clearance when going from "looking low" to "looking flat". At that point you're making a compromise for traction over ground clearance. But once again, 1 psi doesnt mean better traction even if the tire stays on the wheel. Picking a happy medium in there is key and in general is not gonna require sub 10 psi levels anyway.

Play with your tire setup and see for yourself what it does. Once you go below 15 psi, you can physically tell differences in performance per psi you drop. The difference in 14 and 12 psi is huge. A complete game changer in instances. You just gotta try it for yourself.

Now beadlocks and bias tires is a whole different set of rules but I'm assuming you aren't running either.

 

good info. I usually run 16-18psi cause I don't trust my non-beadlock wheels. They still "squish" around stuff, but don't do it so much that I am waiting for it to bust loose.

 

That’s all great info.

My problem has been these cheap ass Discount Tire wheels. They are shit. I have 5 de-beads to prove it.

Now, it hasn’t been the tire/wheel setups fault each time. I’m always pushing the limits that @allmotorrex mentioned. The last time I de-beaded I was running 8 psi. Which in hindsight was to low for the situation...LBL. But, I ran a ton of trails in MOAB at 8 psi with no issue.

I’m hoping to have beadlocks before AOP {fingers crossed}. If I do, anyone want these crap wheels? They’d make good crappie bed weights.

 

17s?
How much?

 

Damn. Tough sell. Hard to say no to that!

 

17’s yes. If the beadlocks come through you can have them. Set of 5.

 

My DYF beadlocks work great!! No issues in the last year or so...

What wheel did you use? How heavy are they? Total cost? Ease of build?

 

2psi

When I didn't have beadlocks it was 10

 

The DIY ring kit is from jester fab, the wheels are forged steel 17x9 -38 proChump series 97 but I would not recommend this wheel. I had to clearance the dimples of the wheel and my calipers to get clearance even with a 1/4" spacer and extended lug bolts. Don't recall the weight except heavy duty, price was good for what you get but dont recall exactly .... 1000$ish I guess. For ease of build I'd say just make sure you get forged steel instead of cast to make them easier to weld/repair. Think I committed more time than skill to the total project

Loved my cheapie Jegs branded steel wheels. Never lost a bead at 8 psi and no beadlocks.

8 without beadlocks 5-6 with beadlocks and broken in tires

 

Gideon and mine are both roughly 56ish pounds per a wheel, hardware, and outer ring.

 

AOP got you motivated?

 

Yeah just really like going camping and hanging out with you douchebags and having the truck makes it way easier.

 

Finally!
You're much stronger than me, don't take 4 days to do it lol

 

You go guuurl

 

I had 2 other mechanically inclined sets of hands to help me. Turns out it makes life a lot easier to have help and the right tools.

Gotta get the flywheel resurfaced then we'll start throwing stuff back together.
