Checked my tire PSI yesterday, I dunno WHAT i was thinking...I was running it at 35 (same as my wagon) - so I bumped it up to 44 PSI (45 is max on my GY mt/s 's) This should bump my mileage up a bit for 'round town/highway

my question: what PSI do you keep, and on what tires? On road PSI? Off road PSI?

thanks,

i you need to lower that quickly. i ran at 38/40 front/back for a while, and now i have over inflation on my tires. i am now running 32 all the way around.

offroading i'll lower it down to 15 to start off with, but that honnestly doesnt do much, 12 is a good place to stop for mild offroading.

for the sand.... I go to FOUR psi

oh ya, i have goodyear wrangler GSAs

yeah, there was a thread about this a few months ago... I think everyone was in the low 30s.
I inflated to 35 after Pismo but that was warm... I'm going to be checking it out when it's cold and try to get myself to 33 all around.

thanks for the info guys - i don't want no fork'd up tires, better lower that then!

I run mine at 35 psi. 15 while offroading in mud and on rocks.

35 here.

35 rear, 32 front.

ditto.

35 for me as well on Dunflop 265-65-17 AT20 for now.

I'm waiting for my Dueler AT Revo 265-70-17's to come accross the pond.

47psi here, max is 50. No tread wear problems either.


Air Shocks sitting at 125psi. (~625lbs of lift) and the rearend is a touch higher than the front end.

~350-400lbs of audio gear in it right now....

Yikes. How's the ride?

I second the:



I run 32 all around as well.

As for what I know with my limited knowledge, each vehicle is different. But what you want to do, is have a flat footprint. You want the flat part of your tread, even across the pavement. And as long as you do that and you are under the maximum psi, then you should be fine. What I question.... is the higher psi in the rear as compared to the front. There is more weight in the front of the vehicle(engine), so theoretically(I've noticed this with my truck anyways), you need a higher psi up front and lower out back unless you are towing or loaded up with lots of weight. I've been playing around with my tires trying to find the right spot so that I'm getting a clean footprint. I'm running about 3 psi higher up front. I'm at 40/37 at this very moment.

32 all around here

Not bad actually, but then again I'm used to how a 1-ton pickup truck rides, lol. I have one of the heavy ass (or ass-end heavy...lol) 2nd gens. Curb weight is like 3984lbs accourding to my registration slip.

I am getting that ideal flat footprint as well.

Haven't had to air down for any offroad stuff, but I dont go offroad a lot either...

Hey guys what about 35 inch 50 PSI rated tires. Why do the shops only fill them to 30 to 35 PSI. They always look low to me.

Bumpin' Yota

That's cuz they are likely low.... But they probably do it in accourdance to what the slip on your driver's side door jam states. That's typically the case after Sam's Wholesale installs my 50psi rated, 6plys. Go fill em up to ~45 and check how they are wearing after 1k miles. All of the beads lines should be wearing exactly evenly - you can use a micrometer's depth gauge to determine each beadline's heighth.
