What tire pressure for BFG ATKO 30x9.5x15's?

What's the recommended tire pressure for this tire? Discount Tire put the fronts at 40PSI and the rears at 45PSI.

35 if you are concerned with mpg, 30 if you want a smoother ride

this thread is going to raise some hell
a lot of people strongly disagree on the psi!
for stock tires you can look on the door panel and it will tell you.

Until you hit the highway lol. Did that for 2-3 mins then got right off on the next exit to find a gas station lol.

Ask Mayledeen how high you need BFG's at.

the place where i bought my dune grapplers wouldn't put anymore than 35psi of nitrogen in them b/c the factory didn't call for anymore than that even tho the tires can handle 50psi i'll admit it rides and handles a lot better than my other 31x10.50's i had with 50psi

Go with what the door jam says (30psi btw). You DO NOT need to change pressure due to larger tires or a large load. Inflate your tires to 30-35 cold and leave them there.

I DD with 25/15. i have virtually no weight on my *** end, and my good tires are back there so i'm trying to keep as much of the tire on the ground as i can.

i've ran around with 12 for a week or so until i was feeling up to the task of airing up

My truck says 30 PSI for 245/75R16's
A Ranger I worked on a couple weeks ago said 30 PSI and it had 225/70R15s!

see a pattern? no matter what size tire you have your pressure remains the same.

Yeah I keep forgetting you have almost nothing back there. I have my bed, shovel, tools, sometimes a quad, lol it fills up quickly
