Just got home from getting new 295/70/17 put on, ill post pictures later, but they told me to run 35psi in them, based on the sticker in my door. Now the tire says Load D, 65 psi cold max and a buddy of mine told me the tire place is full of crap and I should run 50-55 psi in them.

Can you guys chime in and tell me what PSI I should run?

 

Definitely, 35 is way too low. A load range D with that max pressure should be run at about 45 on an F150. 50-55 would only be necessary if you wre maxed out in payload or towing.
At 35 you are just over half of what the tire is capable of handling at max pressure.

 

sorry wrong thread

 

I agree 35 is too low. 42 to 45psi for everyday use.

 

Excellent, thanks guys. I aired them up to 50 and in the morning I'll check them all to see what the cold PSI is.

The numbers posted above, 40-45, are cold PSI correct?

 

Mine say 44 max psi.. what should I run mine at?

 

Stock 255/70/17s? I ran mine at 40psi. Didn't care about wearing them down cause they were crap tires anyways.

 

Correct.

 

I run 65 all the way around and rotate every oil change

 

No nitto terras grapplers. Mine are 305 60 18's with a 44 max psi listed. The stock on mine were 275 65 18's anyhow as its an fx4 not xl, or xlt.

 

WHAT???? How can you possible enjoy driving? I ran about 52 after I posted this thread then waited till morning to get a true cold reading. I dropped it down to 42-44 and still drives like a freakin bolder. The ride is BoUnCiNg as hell. Of course these are my first set of AT tires.
