What tire pressure?
We bought a '79 Ford F-150 4x4 w/351M from auction (it was a steal at $800), only problem is that the tire pressures are all way higher than I think they should be (~50 psi) and it didn't come with an owner's manual and the driver's side door info plaque has been painted over (if it was a sticker) or removed (if it was metal) so I have no idea what the recommended tire pressure is for this truck.
Could someone look on their truck/owner's manual and tell me what the hot/cold pressures are for driving and towing for these older Fords?
Thanks!!!

Look at the tires, they should have the recommended psi. 50 seems high for a half ton-usually pressures that high are for higher load rated tires for the F250's and up.
Usually 30-32psi is the norm. Depending on the tire, and vehicle, usage, etc.
Always check/adjust your tires after driving for a few miles, to heat the rubber up.
It is usually all depending on what the tire is capable of.

Thanks guys. . .yeah. . .the psi on the side of the tire is for the maximum allowed pressure in the tire. . .the max for the tires that the truck came with are like 70 or 75 psi. . .which is not what you would run just maximum that it can "safely" handle. . .although I find that questionable. . .my girlfriend just had a blowout (from heat build-up) in her Cavalier because the tire was overinflated. . .the other front tire was at 60 psi!!! I fixed that REAL fast. . .knew what that should be at. . .usually run it at ~36 psi for better MPG).
I'm pretty sure that the truck should be a little higher than the car, I'm gonna shoot for around 40 psi and I'll see how the tires wear. . .and adjust (or not) the pressure based on the wear pattern of the tires I guess.
Thanks!

Thanks Beartracks. . .that would definitely clue me in to whether the pressure was too high or too low a lot quicker than waiting for a wear pattern to develop. . .not to mention save me some money in the long run!!!
Hard to believe that I didn't think about that myself as I use chalk on my sportbike tires to check my lean angle on a ride. . .
