Can anyone tell me the proper PSI for 30/9.50 BFG AT ?

I've had my Jeep for a week now, and a few days ago I took a trip to the Llano River in TX, and the guys had me air down to about 12. I've been looking on the tire, and I think it's either worn off or just not listed, but reairing I went up to 30PSI. Im thinking thats about proper inflation, but can anyone please give me specifics? Thanks.

Don't worry about the air pressure found molded onto the sidewall of a tire, that is only its maximum allowable air pressure for use when the tire is carrying its maximum rated weight. So since your tires are only carrying maybe half of that max weight, the proper air pressure would be about half of whatever that air pressure on the sidewall would be, if you could see it.

30-33 psi is fine for your Jeep. 30 psi if it's fairly unloaded, a slightly higher psi like 33-34 if the Jeep is fully loaded with passengers, gear, etc..

When you have a choice, buy American.
