Just wondering what PSI should be ran in the tires while off-roading All the times I've been, I've NEVER aired down :pat:



Anyone?

 

I've peen putting mine down to 17 and they work fine for me there. Its harder than some people go but since I don't have any kind of onboard inflation system I can feel comfortable going 60 on the highway without feeling like I have marshmallows for tires as I go to air up again. If I had on board air I'd probably go to about 12.

 

have you had any problems offroad so far? like getting stuck too much? the only reason for airing tires down is to get more traction. so if you aren't having noticeable traction problems then i wouldn't worry about airing down. plus if you have 31" tires it's only gonna hurt your clearance.

 

Na, no real problems yet. I just figured I could score a little extra traction

 

I used to run my 285 MT/R's anywhere from 15 psi to 12 psi. I was scared to go any lower. Even at that pressure they really diddnt fold very well. Probably should have run them 8-10

 

I run my 33's with 8-9 psi. No problems and great flex!!!

 

I never aired down my 265 BFG MTs, but I do air down my 285 MTRs and there was a nice difference. Too much of a difference to say its just a new tire. Slipping off rock doesnt happen nearly as much. Much easier to get up one slowly and smoothly. I hate bouncing.

I go down to 17 btw.

 

That's totally the wrong way of looking at it. How are you supposed to know when you 'need' to air down? And when you finally find out, many times it's too late. I air down every single time I off-road.

12 psi for me.

 

I go down to 10-12 PSI... and have gone as low as 8 on some really nasty slick kayak shuttle trails...

Be prepaired to bring a snack to munch on as it takes a while to get the tires down from road pressures...

 

I just received a set of these in the mail from Group Buy Mike, (XtremeOffroad) on the board here.



Now airing down from 40 to 17 takes less than 2 minutes for all 4. Money well spent IMHO.

 

I second what Matt says on the Stauns. We both got to test them out last weekend for the first time. He let me use his. All I have to say is, these bad boys are AWESOME! Very quick, small (1.5" long) and accurate. A most excellent purchase indeed. I highly recommend these, for what that's worth.

By the way, mine finally came in this week and I can't wait to get back out to use them again!

 

my buds and i use the Oasis Trailhead Automatic Tire Deflators for awhile now and we really like them. I have mine preset to 13 psi.

FYI...
Staun deflators through Group Buy including US Postal Service 3rd class shipping.
$51
No tool required to adjust preset. Leather pouch to store them included.

Oasis Deflators through Oasis Offroad NOT including shipping (UPS only) .
$60.
Requires allen key to adjust preset (included) also included is a stick type pressure gauge and pouch to store them.

I saw the Oasis ones a long time ago but passed because of the price. I was paying $9 for a guage that I didn't trust or need and another $12 or so for shipping. The Stauns through Xtreme Offroad (Group Buy) were the right price for the right product so I snatched them up right away.

$45 Stauns on Xtreme Offroad.com

 

I just ordered me a set from Mike

Thanks Mike!!!!

 

The only reason I got these is because I've used my buddy's set with good results. I paid about 52.00 at a local 4WD shop. There are a lot of guys in the local So. Cal Grand Cherokee Jeep Club that run these. It is a pain to have to adjust with the allen key. But once its adjusted, its very accurate. I run a NIST calibrated air gauge to check my tires. Just my $0.02

 

hey data, what do you keep your MTRs at for street driving? i just got some, and they tire store set them to 48psi. i took it down to 40 but am wondering where i should keep it at.

 

Most keep 'em at ~35.

 

I run my MTRs at 40 for street/highway driving. The higher pressure on pavemant, the longer they last.

Sunday I has out wheeling on some tough rocky stuff and 15 was not low enough. For the forst time since being locked in the rear I had to use momentum to get over stuff. MTRs have incredibly stiff sidewalls compared to my old BFG ATs. I got through but I wished I was at 10 rather than 15. In 2 different spots with the rear locker I spun them till they smoked.
