Tire Pressure
I'm driving a 2003 F-350, 6.0 Lt
What kind of tire pressure are you using when you are not loaded? I've been using the recommended PSI off of the door frame but found that was to much by the centre wearing out to quick. Couldn't find any related threads on this or just couldn't find it. Thanks |
What tires are you running? You can do the chalk test.

I've never heard of the Chalk Test. How do you do it? Thanks |
run a 1 inch or so wide chalk line across the trad of the tire. drive around the block. if the chalk is on the edges of the tire and not the center, tire is over inflated.
if chalk is on the center but not the edges, under inflated. all wore off even, proper inflation. on my 02 diesel i run 55 front and 40 rear with 285/75/16 tires on stock rims. |

For me, running pretty much the same 7800# as a daily driver in an '03 E250 (8,600# GVR) I run 70 PSI all the way around all the time. No adverse or unusual tire wear or handling issues, well over 50K miles on two sets of Michelin LTX's.
When tires are rotated I have to repeatedly tell the techs to inflate to 70 PSI despite what the door sticker says. |
