Why are my tires not holding a bead off road?

Bit of a back story on this new to me set of tires. Falken MT01

I bought this as a set of 5 slightly used tires off of marketplace a few months ago. The prior owner bought them for his OBS Ford but they rubbed too much so they were replaced after a few weeks.

The tires are in like new condition, but had a 6 year old date code on them. I bought these because the rubber was in like new condition, the tires were 6 years old but had been stored indoors the entire time so I didn't think it's a tire age issue, but school me if you think I'm wrong please.

Because of their age I could only get an independent tire shop to mount and balance these tires, none of the chain shops would touch them, so sharing that as a possible factor.

Anyway, I've now got two off road trips under my belt on these and between these two trips I've had 3 flats due to losing the bead on the rim. It's been a different tire each time. Twice the tires got so low they started rubbing and yesterday it lost the bead entirely to where I had to lift the Jeep to get the tire reseated on the rim. Each time I've been aired down to 10 psi.

Any ideas why this is happening and what I can do about it? I never had this problem with the prior set of BFG AT2s I had on it going down to the same tire pressure on the same trails.

Correct me if I’m wrong, but tire bead thicknesses vary, and this affects how well certain tires hold a bead. I suspect this is the problem.

Sell more tires!!!
They are tire monkeys. They are barely able to get your tires and wheels off of the vehicle, new tires put on the wheels, and get them back on the vehicle without a mistake that would inflict serious damage on every other customer. Them are not the folks you want figuring out whether or not it is safe to work on older tires. If corporate doesn't put a time limit on how old of a tire they can work on, then corporate gets to pay the claim for the mistakes the tire monkeys make with their shitty judgement calls. Has very little to do with selling more tires and a bunch more to do with buying fewer crashed vehicles and getting sued by sad families.
 
Going to sound basic, but have you calibrated you're pressure gauge or double checked it with another gauge? You may be lower than 10psi. I had a digital one that worked for awhile then started reading off by almost 4 psi

That's one of the things commercial tire stores and techs are supposed to do weekly to keep their certifications. Michelin comes by yearly to do an audit and you have to have you paperwork in order.
 
"A man with a tire pressure gauge knows how much air is in their tires. A man with two tire pressure gauges is never sure"

I have three and they all disagree.

I will say my 0-20 is much more accurate at lower pressures.

My 0-60 says I'm at 3-4 psi and the 0-20 says it's 7-8 psi. My Morrflate digital is close +/- 3 psi.

I haven't, but I'll add this to the list of things to rule out. When I'm wheeling I air down with a rapid tire deflator that has a gauge but I also have a spare gauge that I could compare results with.

I want to calibrate my gauges. Tell me how.

If you know someone at a commercial tire store, they probably have a master gauge, but if you're gauge is not an adjustable gauge then you're out of luck.

I have 2 Dill gauges, I grabbed this off Googlefoo for a quick reference

IIRC, dial gauges are most accurate in the center of the sweep, so you'd want to use a 20 for air down, ~60 for air up, and ~100 for tow rig/trailer.

I'm a fan of the Morrflate inflator, I tried several, including ARB and Power Tank, and it's the most reliable/leak free for me.

I wasn’t being sarcastic. Digital gauges need to be reset occasionally. I have a 4 tire system that I usually double check. Was way off compared to analog so now I have 3. Both analog were similar Digi is back to same now

I did have an issue a few years ago with tires losing a bead that seemed far to easy. I believe this was due to the no-name wheels that I bought online. At first I thought it was a clearance issue (which wasn't perfect). Ended up replacing the wheels.

Latest wheels I ended up getting are Method Bead Grip. They're not beadlocks, designed to have extra grip in the bead area. I've only had them on a few runs so far, but no complaints and haven't lost a bead aired down to 8.5 PSI.
