BFG All Terrains KO2 PSI

[r47smiley]

I have 35x12.5 r18 BFG KO2 load range E tires on my truck. They state max load 3400lbs at 65psi.

Anyone else carrying at TC with load range E tires that go to 65lbs and not 80lbs? I figure just follow the specs on the tire and call it good.

The newer F load big and tall tires are a nice bump for those running big tires and wanting the load rating of the smaller/narrower tires that are closer to OE size.
They however are not rated any higher than some E rated tires of slightly smaller size.
35s and up are tough duty for TC hauling.

Correct.

Running 305s on stock wheels? Not ideal, especially for heavy loads.

Sorry for the delayed response... Haven't been on the sight in a while..
I miss typed the tire size, mine are 275/70-18. BFG doesn't make any larger 18" 80psi KO2's.

I am running K02 295-75-16 LI 129 Rated at 3950# max psi 80. Highest rated 16’ American made tire I could find.

Your tires sound like D rated? 35’s not good for capacity-more of an off-road tire.

Check out the Nitto EXO Grappler All-Terrain. It comes in 285/70R18.

They don't make those in a AT.

Irregardless of pressure, my last set were KO2's and I was not happy with tire life. I got about 30K on them and the tread started chunking.

I have Michelin's now.

I'm on my second pair. I was told by the Costco guys that each vehicle (and tire size) has ratings that impact the recommended tire pressure for driving. My first set was a custom ordered set (not picked up) at a big discount that were narrower than my present ones (recommended size). I strongly suggest watching the alignment very closely if you want any distance out of them along with five K rotation.

I do quite a bit of varying quality national forest roads and I got like 42K out of my first ones and they were toast. The dealership failed to tighten something at the first alignment with the second set I have now and I went 4K before realizing it and lost 5/32's off of one before I fixed it. Not sure what to do about that. Going to the dealer for alignments is no longer going to happen.

OH, but in terms of performance, they are awesome, particularly in the winter. And they will let you know on a wet road or slushy snow when it is time to get new ones. I promise.

BFG LT285/70/R17 E 126R, 3750# at 80 psi.

That's the reading on the tire --- obviously not, stock, however, GM / Chevy replaced the OEM General 265 tires when those tires fails, and got quite squirrely after riding around a few months ... so, at my request, it replaced those (an allowance) and upgraded to the BFG KO 285's at my request ... I had to pay a difference of $720 balanced and installed...

I generally run them at 65 front, 75 rear, altho it says up to 80 psi when loaded. Nice ride for AT's, and so far, getting fairly good mileage -- less than 50 percent worn at 26K miles, all hauling, and a lot of mountain driving. So, I'll be happy with 50-60K miles

Weigh your truck and then consult the tire manufacturer's tire inflation table to find the minimum pressure you can run to carry the weight on the road. While your tire manufacturer is the best source, looking up the tire size by size and load range, any tire inflation chart will get you very close. The chart I use most often is the Toyo because it's easiest to find. Scroll down to page 27 and your tire should be the top row: Toyo Inflation Chart. Notice that 65 psi is the maximum for an E tire in your size, an F tire max would be 80 psi.

All this said, the maximum you can run is the max pressure on the side wall. Running a tire with higher psi than what you need according to the tire inflation chart will only result in a harsher ride and accelrated tire wear in the center of the tire. Running lower psi than required can lead to a catostrophic failure. So it's always better to err on the side of more psi than you think you need.

Another advantage and why I always run 20psi over required, is the higher pressure reduces sidewall flex which isn't a good feeling with a camper on board. I only need 55psi for my tires when I have the camper, but run 70 or 80(max) to reduce camper sway.

My Nitto Terra Grappler's are 3500 lbs at 65psi. All my other E rated tires were 80 psi. I love the lower PSI as it is faster to air up at the pump.

What tire size and LI are you running? My NTG's are LT285/70R17 E 126R, 3750# at 80 psi.
