Finally convinced hubby to give up what we lovingly called MOBY DICK.....1992 F150 with 386K and engine finally gave up. So now I am on a new forum thread here! For Xmas found him a great deal on a 2006 F150 XL and he is getting used to being in a more modern age truck. It looks like the grandson of the old one complete with contractor cap/roof rack and HEAT and A/C for the first time in 10 yrs for him. He loves it but I need some help with the darn tires. It has P255/70 R17s and having problems determining the correct tire pressure and we are arguing...lol. Not sure if they are the size that came on the truck and I have googled myself to death over the pressure requirement so came here to the 'experts'! Anyone know what the pressure should be? I don't trust what the plate says because we don't know if these are OEM tires. He used to be a contractor but now just does side jobs and has 'regular job' so the truck is not as heavily loaded and he basically uses it for commuting. Appreciate help as always.

You can always look at the sidewall of the tires.. It will state what the cold PSI should be. I'm guessing 35-37 PSI for a "P" rated tire.

If the tire size matches the door plate, you can use that as your pressure guide. If not (like my larger tires that require 50 psi), go by the tire sidewall.

It was dark and very early this morning when he needed to add some air to one tire and he didn't want to take the time to look at the sidewall or the plate....grrr. Will do when he comes home today. I am not sure all 'P' rated have the PSI on the sidewall. He said the old truck was 40 and I don't believe him because the tires were smaller. ......thus our 5:30 AM 'discussion'. He went ahead and set the inflator to 40 and it didn't run very long. I have always been the one to look up and get advice for him on these forums so now I have graduated from 1992 to 2006! Ain't life grand?

Hey Techrep
.....Sidebar: Just wanted to shout out to you in Va Beach. Thats where my hubby was born and raised until he met me and moved to Woodbridge. He went to First Colonial High School. I went to ODU and we met at the beach thru a friend. His family is in Suffolk now.

Outstanding... we live in the Kempsville area by Mt. Trashmore.

Mystery solved. The tires are indeed different size from the OEM tires. The plate on the door says 38 PSI. When he got home we checked the tires themselves and first of all he gave me the wrong size before. They are not P255....they are P235. The sidewall says 40 so we are good to go. Thanks for all the input.
