When you airdown, do you run a different pressure in the front than you do in the back? For me, it seems like 20psi is perfect for the front, but still too much for the back. Next time out I'm going to run 20/15 and see how that does. I haven't had any traction issues yet, so I'm kind of over thinking things, but it doesn't seem like my back tires form to/around rocks as well as the fronts.

 

I go the same all around just because my deflators are all set at the same pressure and they all look the same.

Seriously though, for me on 33's, 12-14 works really well on rocks.

I have gone as low as 4 in the snow and as high as 18 on less severe trails. I just keep it all the same front to rear for convenience.

 

I kept 'em all the same... 15psi.

 

I keep them all the same, 6psi.

 

front=12 on average
rear=8 on average

even that seems high at times, but i dont want to loose a bead.

 

I keep'm the same- 8 PSI for rocks, 15 PSI for Forest Service trails/rough dirt roads.

 

15 psi all around

 

in Pismo i was at 3-4 in the rear and 5-6 in the front, now granted i have no front wheel power, but it still helps.

Staun deflators set at 15.

 

I run 15 all around too, sometimes 12. depends if I'm feeling daring.

 

I always run mine at the same pressure since my 4Runner is pretty well balanced front/rear and I want equal rolling radius on all 4 tires. Using my 4Air system ensures equal pressures deflating and inflating.

 

i normal run uneven front to back. i rather have a little more pressure in front to help with steering on paved/fire roads. so i normally ran my BFG 35" at 18 front/14 rear on most stuff. and than 12 front/8 rear on rocks and sand. this was with 10" rims. i went about 1-2 psi lower on the 8" rims.

i totally believe in airing down since i have sliced 3 BFG sidewalls on rocks or sticks.

 

Interesting.

We had a run to Paragon on October 4th. A dude joined us with his wife in a leased (!) Grand Cherokee Laredo wearing dress khakis and penny loafers. Obviously not heeding the "Get Dirty" logo on one of the Paragon heeps, he joined our newbie party.

Anyway, although he kept getting stuck and in trouble, Penny Loafer took it in very good humor. However, he did slice a sidewall on a stump, and my guess is that his definition of "air down" would be a vertical column of wind headed toward the earth, and not "remove air from your tires." But I digress.

Is that the theory behind airing down? That not only do you gain traction (which seemed to me to be the only reason) but that you are more able to avoid and/or survive hazards? I'm bringing some friends next month and would like to advise them what to do , since I don't feel like wrestling with a hi-lift on a trail somewhere changing a flat tire.

Thanks.

In one way, it improves traction. In relationship to traction, it makes the sidewall softer to help "bend" or "form" around an obstacle like a rock or tree. This helps from the sidewall being punctructured or torn.

 

I keep all of mine the same: 19psi on the street, 3-4psi on the trails.
