BFG All Terrain K02 Tire Pressure Please Help

I just got a new set of BFG K02s for my 2012 stock FJ. The tires are stock size but went with LT load range E: LT265/70R17. I called BFG and they recommended 55 PSI for highway driving. The shop sent me home with 45 PSI in each and felt like the rear of the unloaded FJ was skipping around turns. I just want to be sure I am getting full contact patch with the road, best handling, grip and even wear. In the future, I will be adding more weight--winch, bumpers, batteries, etc. But now my vehicle is at stock weight and worried that I am so far above the stock recommended 32 PSI in each. Any help is appreciated.

I run 40 psi in mine and think its perfect. I have 305 70 16's and a loaded rig, so I think you can air down a bit and be fine.

I run 40 PSI in my MTR,s no issues. If you are concerned with contact patch go old school & make a chalk line on your tread and try different pressures until you get it correct. 55 is the max for a loaded E range tire & we are no where close to that kind of weight.

Actually 80 psi is the max psi for most load range e or 10 ply tires including the BFG. Obviously that's way too much. I have a question however?

What made you put the e on over the load range c? I am going to order the same tire and the same size however in a load rage c. The load range c has more weight carrying capacity than the fj can handle, tread is exactly the same pattern and depth at 15/32 and the load range c is about 10 pounds a tire lighter. My thoughts are they are plenty tough enough and won't hurt the fuel mileage as bad. I am very curious your thoughts on this. Also if you could post a pic of your rig that would be great.

I would think 40 psi would be just fine for your set up. When I'm not pulling my gooseneck trailer with my one ton diesel I lower the tire pressure to 60 all the way around. I have 10 ply or load range e tires on it and the truck weighs 8,853 pounds with no passengers or payload. Food for thought.......good luck, keep us posted.

Re: BFG All Terrain K02 Tire Pressure Please Help

G'day,
You can always play with tyre pressures...try 40psi, if its too hard, drop 2 psi at a time till you get a good feel. also the front n rears can be at different psi ...
cheers

80PSI in an FJ you would pee blood it would be so rough. I weigh in around 5200 empty now and at over GVWR loaded up for a trip. Not sure if the MTR even come in load range C but where I go in AR on one trip i cut the sidewalls on 2 brand new tires and used about 25 plugs to get out to the pavement. Never cut another side wall since I bought the MTR with Kevlar. I wanted the thickest sidewall i could get . Here are a few random pictures from many different trips to the Ozarks in AR

Remember, you will add 3 to 4 LBS when at road temp.

Nice Pics!!! I get 80 PSI is going to be like ridding on solid hard rubber tires, however i was just stating that 55 psi isn't max for a load rand E tire, 80 psi actually is. That's all. For me we don't have a ton of rocks in our area so I'm thinking Load range C rated tires will be good for woods running. Cheers

Re: BFG All Terrain K02 Tire Pressure Please Help

The single biggest contributing factor to people having "brake problems" is over-inflated tires.

Everyone is scared to drop their tire pressures on these stiff-ass tires. Drop the pressure... keep an eye on them for uneven wear and adjust accordingly.

Suck it up... it's only -40
