Tire Pressure for Off-Road without bead lock?

I just had Toyo R/T Trail tires (255/80r17) installed on stock wheels and planning on off-roading soon. Without bead lock, what's the lowest pressures you have lowered tires to without issues? Type of terrain planned is some sandy washes and minor rocky spots.

Thanks in advance!

 

I haven't gone below ~17 or so. That was on sand. I don't know how much lower one can go.

 

Depends on the width of the tire vs rim, construction of the tire and how its being loaded.

I used to run down to 15 or so rock crawling. I ran 35x12.50 on 15x8" wheels though.

 

I used to run my old 10 plys down to 10psi no problem. 20 should give you enough footprint.

 

I'd say 15psi on all 4 tires. That's around where I run when deflating. Keep in mind though, if you are ever super stuck its worth it to air down as much as possible, like down to 7psi. I've only ever heard of tire slippage when traveling too quickly, or doing a lot of rock crawling where rocks and whatnot push tires out of their positioning.

 

Thanks All, I ended up lowering to 25 psi and was good enough for the sandy wash we went through yesterday. Good to keep in mind it can go lower if needed for tougher situations.

 

It’s better to get stuck and get yourself out than have the bead pop off.
