Correct BFG T/A Pressure
Question...I have the stock BFG Rugged Trail T/A 275/65-18 on my '07 King Ranch and the placard on the door says to infalte the tires to 35 psig. The label on the tire sidewall says that maximum inflation pressure is 35 psig.
I saw that bellman said his BFG T/A in the same size says maximum tire pressure is 65 psig.
Am I the only one with low pressure BFG's ?
Thanks

His are a different size and load range, and possibly even a different tire, as he did not say which model. Yours are the OE tires that came from Ford. Other OE brands in the same size, like the Goodyears are a LR C tire and would have a different placard.
Yours are a P series tire (passenger car), a load range B.

Thanks kingfish51. I guess I didn't realize that my OE tires were classified as passenger tires even though my KR has the 7200# GVW and towing packages. That's probably why the truck rides and handles so nicely.
I do want to upgrade to a larger size 18" on the stock rim. Any suggestions? My truck isn't lifted but I will probably put the Bilstein 5100's on it to level it. I was thinking of going to an LT285/65-18 BFG T/A. Heard some good things about it on these forums.

I have the BFG AT/TKO 285's and have been running 40 psi for the last 20k. Getting ready for a small trip this weekend and checked tire pressure. All good. On a whim I upped the pressure to 50psi. Immediately noticed a much firmer ride. I think I'll do 50psi up and 45 on the way back... see what's what.

If your vehicle had come with a TPMS setup and those tires, it would have been set to show low pressure at 46psi.

At 40, you are at half or less of the load carrying ability of the tire. The GAWR of the F150 is about 4k per axle. At 40 psi, a LR E 80 psi tire doesn't even come close to be able to carry that load.

Just got off phone with BFG customer service. They calculated that for regular driving, optimum pressure for those tires on my '05 supercrew to be 41-43 psi.
