OffRoad tire Pressures

What PSI do you run

  • Total voters
    112
On road: 34 F 32R
Off road: 20 both

Stock TRD Pro rims and stock Terragrapplers 265/70/17

Next up for tires 275/70-17 OR 255/80-17 Either in Falcon Wild Peak AT3
 
Depends how dedicated the terrain is, most stuff is a mix so I tend to stick with an all-around pressure.

Summer - Goodyear MTR/k 285/17 r17 stock trail rims
Winter - Goodyear DuraTrac 255/75 r17 stock trail rims

In general, same for both seasons:
37 on
20 off
 
I have yet to take the 4R in anything requiring me to significantly air down, but I wouldn't hesitate to go to 12 or 14 in soft sand..

On my off road rig, 37 inch toyo MT's 14.50x15 I regularly air down to 12 PSI and I don't have bead locks..only once did I have an issue where the side wall got up against some limestone which in turn got ground into the bead and caused a leak.

If you're cruising trails where you want the comfort of some extra traction, I would think anything between 15 and 20 would help a lot on the 4Runner..

Truck weighs about 5,500 lbs

BFG K02 C-load 285/70R17.

37 highway
17 off road

Makes a huge difference on very rocky Colorado trails such as Hancock or Williams Pass.

I was doing Gold Mountain which has 2 large water falls ... And I was told that 15psi was still too high. I'm on 35x12.5x17

305/70/17 MTRs. 31psi on road in winter, 35 summer. Normal trails 10, rocks 6-8, snow 4. No bead locks, never lost a bead.
 
LT 285/70R17 C-Load

16psi on very rocky terrain 40psi on road.

Dont remember weight but 4 people, 2 dogs full load inside and full load on roof for camping.
 
KO2 265/70R17 C- load

On road 36 psi
Off road 12 psi

2010 Trail with factory wheels.
Mainly drive on trails with loose rock sharp rock, roots and pot holes. Basically logging trails in in BC.
 
Factory TRD Sema (Pro) wheels and factory installed Nitto Terra Grapplers (265/70) that came on my 19 ORP

We're in Louisiana, so it's mostly washed out roads (the street, not offroad), gravel and dirt roads, mud, roots & stumps, and not a whole lot of rocky terrain (there is some in N Louisiana).
I'm usually around 38-40psi on road, 18-20psi offroad.

I'll be swapping to 255/80 Nitto Ridges and 17x8 0 offset wheels after I get my lift installed and the Sema/Pros & TerraGrapps will go on my wife's 19 Taco TRD OR.
