I am going on a camp out this weekend and will be traveling on some pretty rocky/sandy roads with my 05' Dodge 2500. Right now I have my tires at max PSI rated for the tires, with the Cummins weighing so much, how low could I air down on these roads without being too dangerous. I know what to air down on my rock crawler, but the Dodge is a whole other beast. I am currently running 35" BFG At's......thanks for any insightwaytogo

I've run my tires down to 10psi in the rear and 15psi in the front. But I've also got an onboard air compressor so I can fill the tires back up after I come off of the sand.

Its all honestly a question of the terrian I would try to stick around 20s.

Even going down to 30 from 70-80 would help quite a bit...

personally i wouldn't go too much below 30ish in the front but id go down to 20 in the back

Thanks for the replies guys! I ended up not airing down at all and did most of my exploring on my Polaris 700 Sportsman. The last town I stopped before my camping trip was chargin 3.20 A GALLON!!!! I decided the quad was a more conservative fuel choice....lol


BTW the BFG's did awesome on rocky, rutted, and washboard roads I traveled on to get to camp!!!
