I have pretty much the exact same truck as you except mine came from the factory with the Goodyear Wrangler ATS load range C tires. They are supposed to be inflated to 40psi according to the sticker on the door jamb.
Wow, at 41 psi, I had vibration, noise, poor mileage, and they felt flat with it harder to accelerate than normal. I put them to 55 psi as to what BFGoodrich said, and they felt great. My mileage went up about 2 mpg, vibration went away, tires didn't feel flat and acceleration the same as with OEM, and tire noise went away.
I'm really surprised at 40 psi because the load rating on a LT tire is so low, I can't believe Ford would do that.
What payload rating did they give you on the tire placard?? Also, what axles to you have. I have 3750 lbs front axle and a 3850 lbs rear axle.
That 40 psi blows me away. How's your ride and do you get decent mileage with the tire aired that low??
A member at the F150 forum took a pic of tire loading sticker on his F150 HD Payload package truck. That truck has a 4050 lbs front axle and a 4800 lbs rear axle. The truck comes with LT245/75R17E tires. His placard states 55 psi for the front 4050 lbs axle and 60 psi for the rear 4800 lbs axle.
Thanks for the help.
