Question Tire pressure

[Friis]

Well, here a real rookie question...
What is the recommended air pressure for front and rear tires on a 2000 F-250 Lariat 7.3 4x4 Supercab on stock wheels/tires? The manual says to check the label on the drivers side door, but being an export vehicle, mine hasn't got one. I've tried googling this and searching the forum, but I guess that nobody needs to post this info, as everybody has got the sticker...

Thanks!

I run 60 PSI all of the way around. Bit firm but I don't have to worry about carrying heavy loads on a daily basis.

Depends on how many ply tire you have should tell you on the side wall the max psi and go from there.

60/70 front/rear for my '02

Thanks. Figured it was around 60, but it is good to be sure.

I have a dually, i run about 70 front and 50 in rear, this is empty. with high rear pressure it drives real rough. Hook a trailer to it and 75 psi in the rear and drives fine.

i just run 50 all the way around... i never pull with mine and i rotate every other oil change so its easier to keep them the same... it really just depends on what you use your truck for and what you prefer... the more psi the rougher the ride... you need a lil more if your hauling and a lot of times people with run a lil higher in the front than in back...

I run 65 all the way around...its a rough rider no matter what and they seem to wear the best like that.

our friend to the north does tires in kPa... (i crack myself up sometimes)

regardless of configuration, the way to do it is the chalk test or puddle test. you will be inflating the tires to the TRUCKS configuration, not some comparison to some similar or not so similar truck...

here is a decent writeup-
Technical Information: Wheels and Tires

" The "Chalk Line Test": Draw a heavy chalk line across all the tread faces. drive slowly forward in a straight line for a few revolutions of the tire. Get out and observe the wear pattern of the chalk. If it has worn away evenly, then the inflation is correct. If either the edge or center of the line is worn first, then the tire is under or over inflated, respectively.

The "Water Puddle Test": Similar to test #2, but drive through a puddle of water in a straight line, then get out and observe the wet tire tracks and see if the wet imprint is even, especially as the track starts to dry out after a few revolutions."

Overinflated is center part of the chalk line worn away, underinflated is the edges of the tire worn away.
