    Argo AT189 Tire PSI?

    The Argo AT189 tire lists a max 7 PSI. Currently I'm at 4.5 PSI (via low-PSI pressure gauge). What do you guys suggest for a PSI for that tire on wooded trail terrain on a 6x6? Thank you.

    1.5 - 2 psi if you are not going to encounter rocks large enough to pinch the sidewall against the rim.

    Otherwise, 2.5 - 3 psi. The Argo tires give a great ride; even better at lower pressure.

    Look in your owner's manual, they have recommendations for different type of terrain. I run mine at 3psi.

    ...The manual manual lists 2.0 to 7.0, but then just lists low, high, and highest. I'm thinking 5 PSI or so is about right for my terrain. Thanks.

    That's not what my manual says. 2.5 to 3.5 psi for the Carlisle 24x10.00-8, maximum operation pressure of 5 psi. 3.5 to 7 psi is listed for the 25" Rawhide.

    There is a big difference in ride quality between 5 and 3 PSI as well. I would run 1.5 to 2 PSI unless you start losing beads and then you can raise the pressure up to 3 PSI. Really, on a basic trail, popping a tire off the bead shouldn't be an issue. That typically happens when you are in a rut and you hit the side of the rut with the tire and not the wheel.

    From the 2011 Argo Owner's Manual:
    The tire pressure should be adjusted between 2.0 and 7.0 psi
    according to differences in terrain. Observance of these guidelines will lead to less wear & tear on both vehicle and tires.
    The operator should equip the vehicle with a low pressure tire
    gauge (Part No. 619-10) and with a hand pump.
    RECOMMENDED GUIDELINES for TERRAIN
    Soft Ground:
    Low Pressure • On soft terrain, use lower pressure.

    Hard Ground:
    Higher Pressure • On hard terrain and water, use higher pressure.

    Rocky Ground:
    Highest Pressure • On rough or rocky terrain, fill to, but not more than the recommended range indicated on the tire sidewall.

    If you believe that the manual is a better resource, why seek experienced opinions here- ?

    Bud, I sought the advice of experienced users her because, per above, the Owner's Manual is vague and unclear -- and peer advice is always a meaningful addition to manufacturers' recommendations. Thank you.
