Air down

[badfish4tail]

I know this question might sound silly to some of you old timers but i got to ask....What is the PSI i should have when i air down before hitting the trail.
I have 35/14.5x15 boggers on 15x10 rock krawler rims...Thanks

im in the dirt alot so i run about 18-20. sand and rock crawling i see people run down 8psi. matter of ure driving style and terrain. maybe others have more input but seems like no other opinions have been offered. start playing around while u wheel to see what u like.

btw, i have 35" 15.5x 10 bf mt's

With my 12.50 33 MTs I usually air down to 15-20 lbs for rocks and soft stuff.
I go down around 12 PSI for snow wheeling. Thats about as low as I would want to go and not worry about poping a bead.

13 psi is what I run out here in the rocks.

 

[badfish4tail]

thanks for the info...think i will start out about 20 psi

With smaller tires you can't go as low as with bigger tires because you still need ground clearance but with some 36s I had I would go down to 5 on the snow 8-10 on the rocks and sand and 15-20 for mud if you are going to go down to the levels where you could possibly pop a bead you may want to figure out a way to reseat it beforehand I use the starting fluid and match trick has always worked for me but it might be best to go get a junk tire and practice

bias swampers can go pretty low without losing much ground clearance.the thicker sidewalls can hold up the truck alot better than radials. i run my 33" tsl's around 10psi on the trail and they barely bulge.

radials usually cant take low pressure like a bias can. my radial A/T's look flat at 18 psi.

i would start at 15psi and keep going lower till you have problems. 8-10psi would probly be perfect.

I've run my old worn 36" TSL's as low as 6 psi in the sand. Even then there was not much buldge in the sidewall and I never lost a bead.

Bias Swampers will easily tolerate single digits.

i just started running boggers a few months back and they are STIFF. on my rig i run 11 psi front and 8 rear and they still dont bulge unless up against a rock or other obstacle. when running the tsls i couldnt air down as much, but i think u can try wheeling at around 10 psi for sure-play with it and see what ya like the best Later Ryan

Are you running 15" rims? I've been nervous to air down more than 15psi front and rear since I lost a bead on my old 38's. I currently have 44x18.5 swampers on 16.5x12 wheels. I'm just nervous about losing a bead while I'm sideways on an obstacle, I'd really hate to flop it and hurt anyone in the truck (sheet metal is repairable).
