92Path_68CJ Posted November 7, 2013 Share Posted November 7, 2013 (edited) With my pathfinder I ran 35 on road, 25 off and on very rare occasions 20. (What can I say, I hated airing up later.) With my CJ I've finally gotten into airing down, 15-20 PSI off road, 30 on. Edited November 7, 2013 by 92Path_68CJ Link to comment Share on other sites More sharing options...
ahardb0dy Posted November 7, 2013 Share Posted November 7, 2013 Usually run 30-32 on road, off depends would depend on the terrain, in my old hardbody with 33" or 35" in deep sand might run 20 PSI. mud/snow same as on road. Don't ever run the max that the tire says on the sidewall, you need to look at the rating for ex. if the tire says 35PSI at 2500 pounds than take the 2500 pounds x 4 = 10,000 pounds, does the truck weigh 10,000 pounds? No? so than you don't need to run 35 PSI. Best way to determine the proper air pressure is the chalk method, make a chalk line across the tread of the tire, drive straight, look at the chalk, worn away in the center, too much air, worn away on the edges too little, repeat until chalk wears away evenly across the tread.

Karmann Posted November 10, 2013 Author Share Posted November 10, 2013 I personally go with 35 on and down to 22 off. Except every time I take it to the stealer ship or alignment shop, they take it down to 30, which is very frustrating in an OCD way... Link to comment Share on other sites More sharing options...

nunya Posted November 10, 2013 Share Posted November 10, 2013 I currently don't have a clue what's in my tires at the moment... Not flat? when I switched over to them for the winter I had to put stems in 2 of them and if a bead leak, I think I set them at 30psi (still fair wearer road use) but that's firestone destination a/t 31x10.5s on 15x8s on a 2 door wd21 driven by a scrawny dude with a couple fishing rods in the back Link to comment Share on other sites More sharing options...

Towncivilian Posted November 10, 2013 Share Posted November 10, 2013 I run 26PSI which is what is specified on the door jamb. Maybe I should find the correct pressures based on the chalk trick; I didn't know about that. Thanks for the info. Link to comment Share on other sites More sharing options...

Tungsten Posted November 12, 2013 Share Posted November 12, 2013 I was going to say, better mention size of rim, make, model and size of tire and load rating as well. Too many variables for an easy comparison... B THIS The tire pressure you run depends on the design of the tire. For a 31" on a Pathfinder, you should not need to run more than 33 PSI on an All Terrain tire because of a reinforced sidewall. On the contrary, highway tires benefit from higher pressure because they have softer sidewalls. You can run highway tires as high as 40 PSI. You can always air down off-road but I can't say how much because I never ran into a situation that required lowering tire pressure. Also, the recommended tire pressure of 26 PSI is for the tires that were included with the truck. They were not that great. The pressure was reduced for a soft ride but if you don't keep it at 26 PSI all the time, it will get dangerously low. You lose pressure in the tire when the temperature drops. You always want a little overhead to account for that. Link to comment Share on other sites More sharing options...
Inyourface1650 Posted November 13, 2013 Share Posted November 13, 2013 I notice many of you run comparatively high (20+ PSI) off road. May I ask why? I typically run between 12-15. The ride is vastly superior (especially with the 9000XL's on 0), the tire grabs much better, and I've never blown a bead yet. Though I have watched someone do the ether and lighter trick Link to comment Share on other sites More sharing options...
Rebelord Posted November 13, 2013 Share Posted November 13, 2013 Pretty much dont want to blow the bead. 31x10.5 on a stock 7" rim is pushing it for me personally. 20 sits nice in my STTs Sent from my Moto X! Link to comment Share on other sites More sharing options...
