I have BFG A/T 285/65/18 on my 04 F-150 FX4 and my front tires look low to me, is there a recommended psi for just normal every day driving?

 

ford recommends 40 but I run 45 in the front and 35 in the back unless Im towing then I bump the pressure up a bit. Im running Firestone AT's though so it might be different for your BFG's.

 

35psi all around.

 

Ive got General grabber red letter tires, 35x12.5 r20, load range E. I'm running them at 45 psi all around and they are wearing well...

 

I have BFGs A/T K/Os 285.65.18s and Im running 50 all the way around. tires are wearing even.

 

Look at your door jam sticker and run whatever it tells you even if you have LT tires for daily driving.

 

Door jamb sticker is for the tires that come Stock on your truck...if you noticed theres a tire size on that sticker also...this PSI is for that tire size. Most off road tires like BFG A/T M/T require more PSI and normally have a MAX PSI COLD...my BFG M/T has a max PSI COLD of 65 PSI...I run 40 in the winter and 50 in the summer. works great for me..

 

The max cold psi on the tire is for the amount of air that tire needs to support the amount of weight that the tire is capable of carrying. It doesn't matter what tire size is on the door jamb sticker, that is the amount of air that is preferred for that vehicle

 

That's not correct... Once you wear out your stock tires or switch to a tire that is a D or E load range, then you need to follow the manufacturers specifications of your new tire.. (Disregarding the door jam stickers specification)
If you ran 30 psi in a load range E tire, you would not only hate the mushy ride quality, but you will wear it out quickly...

 

It has nothing to do with it being a d or e rated tire. If your vehicle says 35 on the door jam that is the recommended air pressure to support the weight of the vehicle no matter what the tire size is. Now if you do haul stuff or pull a trailer you can run them at a higher psi. If I ran 80 lbs in my 33s like my tire said my truck wouldn't stay on the ground. I have always ran the recommended by the truck in my oversized e rated tires and have never had a problem with them wearing out
