Right now i am running my 285/70-17's at about 17.5 PSI or somewhere in there...maybe 18. I was wondering if i could run my tires at 15 PSI. I have the factory 17" wheels. lol this is for the trail.
the tires are KM2's and i have a 4 door if that helps.

I run by 35" KM2s at 15 PSI often. No problem so far. 15 is about as far as I would go without beadlocks, though I know some go to 12 with no problems.
There is an advantage with slightly narrow rims - it will be harder to spin a tire on the rim.
I say go for it! Just have a compressor or spare handy in case you pop a bead.

thanks guys!! well on my CJ-7 i have 33x12.5-15 MT baja claws with 15x8 steelies and i run them at 12 with no problems either. cause i have been running these 285/70 KM2 at 17-18 area and i wanted to go lower. in a couple weeks i will be going to some steelies, 17x9, so i should be able to run them about the same preasure.
lol im out in Moab so i wanted some more traction on that slick rock!!![Thumb](https://www.jk-forum.com/forums/images/smilies/thumb.gif)
you guys think i would be able to do Moab Rim trail or Cane Creek? I have a 2" BB with these 33's and the factory rear locker and electric discos...and rock sliders.

I run my stockers at 10 and never had a problem....well that is until I had 20 feet o trail left and put a really nice nickel sized gash in the right rear!! But I haven't popped a bead yet!!

You should be fine on Kane Creek, as long as you're with a group and someone with you knows the trail well. It's easy to get lost.
Moab Rim might be tough in a 4-dr, but I'm sure you could do it.

I don't need to either. However, I rather take the 5 min to air down than pay the $200 fine. That cash would do me much better in the tank.
