Ive read many articles regarding this but I would like
to hear your thoughts about tire air pressure and sidekicks.
My tires can go up to 44psi
And my Factory Chart says a Geo Tracker should have 23psi
(but that is for stock 15s not aftermarket 18s)
your thoughts please?
(what did you guys do with your aftermarket/offroad tires?)

With 18's you probably have to do a trial and error test, I'd definatly start high, say 35psi, take a drive - it will be rough, you can't escape that now - drop it down in about 2psi incrimints going no lower than 25psi. large rims with low profile tires need to have a higher air pressure to lower the risk of rim damage from potholes. I run 36psi in my 17's on my civic, we have some pretty nasty roads with poor maintenence and I've managed to get through 6 years with oversized wheels, while I check out local clubs and people complaining about broken and bent wheels - probably running stock 26/28 psi in their tires. Not sure if anything I've said is factual(like most things I say), but it's just my experience.
On my trackick, when I had my 30's installed(on my 15" rims), the tire guy filled them to 32psi. what a nasty ride down the street(50km/h) :o I pulled over and dropped them to 20psi, that was better, but still a little rough, so I dropped them to 16psi, much better, but now it's pretty active on the highway(100km/h), I'm thinking on going back to 20psi as it handled better at higher speeds(100km/h)

I run my low profiles at 30 psi. At first I ran my rubber with the specs on them, and almost immediatley they were wearing bad. What kind of driving do you do? Since you're low (like my four door) you probably stick to the pavement, so unless you are a puddle jumper, 30 should be fine. If you run your tires at 44psi (unless you have air bags installed...) you'll feel EVERYTHING. I live in the worst place for roads, and my rig is low, so I pay lots of attention to my tires and shocks. But like Uncivilized, my suggestion is based on experience, not tested and proven 100%. Just experiment a little and keep an eye on three factors: Wear, ride and handling. Hope this helps as well...

first off
its kinda funny how everyone says their roads suck
(because youve never seen Hawaii... bleh)
but all this great and from different prospectives!
keep em coming!

i'm running 31 x 10.50 bfg all terrain at 18 pounds. much more than that and every bump drives you crazy.

Ross,
I'm running the same tire in 30 x 9.50 and keep mine at 36/34 (f/r). What kind of wear are you getting? I've got over 63K miles on mine and they still have plenty of tread. I'd love to soften the ride (actually, my wife would like the softer ride...lol) but I'm hesitant to drop the pressure because of increased tire wear. BTW, it's a '91 that I use as my DD and mostly at 50+ mph.

they wear just fine. the soft ride is nice. i have the 5" calmini spring under. every little bit helps. try it i'll garenty you'll like it it.

Hmmm... ok
I started with 23 and the ride was "ok"
Then I went to 30 and it was still ok
Took it for an alignment and they put in 44 to be safe
(very bumpy)
Got home and brought it back down to 36
(so well see how that goes)
How about everyone else?
What did you do?
