Destination AT2 lowered pressure

[jblc]

For those of you who run Destination AT2s on 17" rims, what pressure have you safely aired down to when off-road? I just put on 265/70R17s
I'm not sure where to look this up, as Firestone's site didn't seem to have any guidance...

I usually air down to 18-20 psi. Mine are Nitto Ridge Grapplers and the same size, the AT2's should be the same.

On the Revo 3's I ran and the XT's I currently have 18-20 PSI is what I would usually run off road.

The XTs are 10 ply though, no? Doesn't that mean you can air down further than AT2 (4 ply) without the bead seal breaking?

Maybe but I don't have a need to. Also going down further it would be best if I had bead lockers.... And I do not have such

Thank you both
As a sanity check, what pressure do you run on the highway?
I did the chalk test, and came up with about 33-34 psi -- although I think the 34 would be optimal with cold tires, not yet running hot. So perhaps 33 psi, so that when hot it's more even wear.

I run mine at 32 cold and rotate them every 5,000 miles. So far they've been wearing great.

I'm running 30 cold but thay is what I found works for me. Each vehicle will have its own setup

I wouldn’t hesitate to run 15-18 lbs off road (no fast stuff). Do it all the time, just did today for 5 hrs
Plan on doing it again next weekend.

18 lbs should be safe.
