Hello everyone what are you guys running for tire pressure driving empt for a e350 aired mine down to 55 psi on all 4 tires. Just curious because I am told it helps with tire wear? Thanks
I have never had mine above 55psi, there is no need for max air pressure unless the truck is fully loaded.
yes that what I figured fuel mileage dropped a little and low tire pressure light won’t go off but I think it will help with tire wear I did a chalk test and all wore off almost perfectly straight across the whole tire.
I dropped the TPMS trigger pressure to 50psi with Forscan on my 2011. Did you notice the center tread wear more with 80psi? I dropped it mainly for the ride improvement.

No don’t have a scan tool on my old van that were set at 80 in rear and 60 in front lots of wear on front tires not evenly. Why do vehicle like the e350 say on the door sticker so higher pressure and causes premature tire wear?
It will not cause premature tire wear if the van is loaded
It also won't ride like a steel wheeled s hit spreader with a load
Good job using forscan to tell your TPMS to allow a lesser pressure Conanski
