Hey im not exactly sure how much to air down, im told usually 10-15 psi, but see i have a 15 by 7.5 rim with 32x11.5 tires, i dont wanna air down too much since the rim is small, and i dont have beadlocks.... any suggestions

I have seen someone running your same setup go down to 12 and be fine.

MasterShakeXJ

depends what your doin i would think.

studmuffin

12 would be good then. well how much should i take out if im doin some rock crawling.

afbond03

Lowest I have ever went is 15, and that is on the rocks in CO. I haven't had any issues and most of the "gurus" I go with say that is fine.

studmuffin

oh really, ok well thats fine yeah i heard 15 was the ideal psi but i jus didnt want to go too low since my rim is not that wide, dont wanna have a popped out rim and tire in the middle of the texas desert, lol

in the sand, you want as low as possible. i run about 8psi in the sand.

studmuffin

yeah i do hava alot of sand over here, but would i run the risk of my tire popping off with 8 psi, my rims are only 7.5 and tires are 11.5.

i used to run about 10 psi with that setup, bet i could have gone lower if i wanted

I was also wondering how far to air down on my 235/75/15's AT's the lowest i have been so far is 15 and it seemed to be fine for the mud/sand since fla is full of it lol......

studmuffin

oh really wow and you never had any issues with that set up

don't forget tho, tire sidewalls have a lot to do with it. if you have a heavy sidewall that doesn't flex much, you can go lower, as with new tires will be more stiff as well.

what tires are you running? how many ply is the sidewall?

i run 8psi with 8" rims and 10.5" tires

ktmracer419

the tire has alot to do with it.

my 32's were kumho mt's

i have run 37x13.5 bogger on 10" wheels at 6 psi

37x12.5 creepy crawlers at 5 spi on an 8" wheel

36x 12.5 swamper tsls couldnt hold a bead at 10 psi for some reason on an 8" wheel

36 x 13.5" iroks at 5 on a 8" wheel, (2 on the beadlocks)

studmuffin

well im running bf 32, not sure how many plys they have, is that good?
