Hey guys,

I have a 2006 Jeep Wrangler. I just bought BF Goodrich KO2 the size is LT285/75/16. I was wondering what tire pressure I should run so they all wear evenly? They have 35 psi in them right now. They guy who installed them said I should run 31 to 35 psi. What do y’all think?
 
I run 25psi on the road and have no issue with excessive tire heat. Handling and ride comfort are great. I run 80mph on interstate. Offroad I usually run 15psi. I might go lower when in the dunes. Mine are E rated so the side walls are stiff. 35psi on a light TJ is too much and I think you would get center wear. Most effective way to get the most miles from any tire is to rotate them regularly.
 
Really depends on your Jeep, the conditions and how you drive.

When I had 33 KO2s on 15s they did great at 28 psi.

I think the theme here is lower pressure than you might think. I run 22psi in my 33x12.5r15 load range C tires on a 3600 lb TJ and they are wearing evenly. Lighter vehicles, higher tire volume and stiffer sidewalls all need lower pressure. Your LT285/75R16 are 32.8x11.2r16 in imperial speak and so are moderate volume. They are also E rated with a max load of 3750lbs at 80 psi. One tire could probably carry your Jeep and be within its load range. They are truck tires. I would try about 25psi, maybe less.

I have 30x9.5x15s and am currently running them at 28 psi.

I think I'd tried down around 26, but felt it negatively affected fuel economy. (Maybe not, but worth the experiment.)

Thank you I didn't think that I could deflate that low.

Thanks. I am going to defiantly lower them.

It should drivec much smoother just dropping the pressure. They should wear evenly, but keep an eye on them. Everyone here runs these pressures and have for years with no issue.

35 is too high for that size tire which is essentially a 33" size tire. 26 psi is usually appropriate for when your TJ is lightly loaded, 28 psi when your TJ is fully loaded with people and/or gear. And when aired down for offroad use you're not really airing down until you're under 15 psi for tougher trails. 12-13 psi would be no problem for those so long as you're not running an extra-wide wheel like 10". Most at that size are running 8-8.5" wide wheels which are perfect and hold the tire more securely than 10" wide wheels can.
 
Adjust your pressure for these parameters.
Avoid heat build up which is deadly to tires. I run 10psi in the dunes and have never popped a bead or had excessive heat build up.
Adjust according to load. The listed pressure is for full load capabilities. TJs can not handle the full load capacity of an E rated tire so 50lbs or more is not needed.
