Best tire pressure for BFG KO2's?
2013 Platinum SCREW 5.0 4x4
Wondering what psi you guys are running your KO2's at? I recently installed a set (275/65/20) and have been keeping them inflated to about 34 psi. 95% of my driving is on paved roads. I purchased the tires because I wanted something tough and reasonably puncture resistant as I travel to construction sites where I'm subject to unpaved roads, driving in sand, mud, gravel and lots of nails, screws and other nasty debris.
One of my coworkers also has a set of KO2's on his Excursion, and he told me I should be running them at 90 psi. He stated they would be much quieter on the highway, wear a lot longer, and the truck would corner better.
Should I crank up the PSI? What's your experience? Thanks!

If my truck is empty and I'm not hauling anything I'll keep it at around 34 psi.
I've spent a lot of time reading up on Load E tires and what people think about it, you'll get all sorts of answers ranging from the low 30s up to "if you run less then 50psi your sidewalls will blow out and you'll die a fiery death!".
I've ran mine like this for around 20k miles and they are wearing nice and even. Just know with the lower psi you'll be giving up some MPG for the more cushy ride.
Your buddy is nuts, 90psi is insane.

Here are multiple approaches to setting the correct tire pressure for YOU! It all depends on your vehicle, tires, what you do, etc what the correct pressure is for YOU! Everyone elses can be close but maybe not ideal.
There are two "best" ways. Either use step 2 in the following link or step 4. I prefer the chalk test as it accomplishes the same thing and takes 20 minutes and costs nothing if you have sidewalk chalk or $2 if you don't.
Method 1 and 3 are good estimate ways but are going to be estimates. You can at least get close with these though.

I have the exact same size as you and I run mine at 45psi. The wear has been really nice and even. Like you, I run mostly paved roads and hardly any payload.
90psi is too much. Look on the side of the tire. There should be a spec saying what the max pressure is and not to exceed it. On the BFG site, the max load capacity for KO2 in this size is 3750lbs@80psi. Deviating from that pressure either decreases load capacity or puts excessive stress on the tires and is more susceptible to blowout, so there's no benefit to running higher than that.

90 PSI is insane and he's just asking for a blowout.
On a F150, you're not ever going to max out the capacity of the tires so you should not be running anywhere near the maximum allowable PSI listed on the sidewall. I run mine at 35 PSI in accordance with my door placard but some guys run theirs a little higher because they don't mind the harsh ride.
