how low can you go? with the tire pressure on a non-beadlock capable tire!

I was wondering how low could I go before the tires slips off.

Found this article here: https://www.drivingline.com/article...ext=The first is the most,the tire to de-bead.

And the money quote: "The first is the most important. If you are NOT running a beadlock wheel, we highly recommend you AVOID dropping your tire pressure below 10 psi. Going below 10 psi without some type of locking mechanism to secure the bead of the tire to the wheel can cause the tire to de-bead. "

that was an excellent article El Chorizo, thanks . I'm not gonna be dropping below 20 PSI anytime soon!

I've done 17 psi on Drag Radials many times at the drag strip without issue

what do you have for compressor? and where did you put it? I'm thinking to install this hidden one behind the spare!

I drove around on the tires with about 25 PSI normally and would deflate them to 16 while at the track. Drive it home and fill them back up... I didn't carry anything special with me.

Here’s a picture of what 10 PSI looks like on a non-beadlock rim in deep frozen ruts in deep deep snow….

It took about an hour and a half to dig out enough room to get a jack on recovery boards and space to remove and replace the wheel/tire. About another hour fooling around getting the wheel off and spare on. The wheel/tire is heavy and trying to line up the wheel with lugs while it’s sitting down in a rut is not as easy as one might think!

I own beadlocks now…

Ouch, looks like a headache. Was that 10psi before the snow or after the freezing temps? Tire pressure will drop with temperature drop too. So if you started at 12 and then got into the snow could be down to 8psi!

Also, love your username. My favorite book.

Went down to 10 psi after a mile or two in the snow. Not much change in elevation between the air down point and the lost bead location.

I’ve gotten away with it before, but the high walled rick solid ruts are less kind than fresh powder.

Ahh I didn't even think about altitude changing the pressure. Just a temp change. Most of my knowledge doesn't come from off-roading but from drag racing. Air pressure will rise after a burnout and the air in the tires is nice and hot. Will be much lower when cool.
