E Rated tire psi for 1/2ton

[liquify33]

What psi range should I be running unloaded and stock?

TIA

Load range E. What does the sidewall air pressure say? That is for a load condition. Run it 10 lower psi otherwise. Too much air will wear the center of tire out first. Too little air will wear the edges out first.

80 under load
Neighbor with a 2500 diesel runs his E’s @ 50 unloaded. By the specs 23-ish is about right for 1,700 per tire (based on factory #s).

It rides well @ 30, 35 was harsh but they were brand new and feel better now with a couple hundred miles on them.
I don’t wanna kill them, but I don’t want to kill my back either!!

Personally, those lower pressures are too low, IMO. The load range E tire has the stiffer/layered sidewalls and to go that low on pressure seems like it would flex them too much and weaken them. Again, IMO.

I meant to say 10psi lower than load air pressure. You can play with that but I like to get the max wear out of my tires and sometimes comfort be damned. I haven't ran a load range E tire in so long. Plus, they always have the taller sidewall. E is for a truck tire and those have the taller sidewall.

Thanks guys, gonna run ‘em up to 50 and see how that does

50 psi rides well, thanks as always to wisdom and experience of the OBS crew.

I run 33in BfG KO2 load E at 35psi when empty and 45-50 loaded. Any more psi empty and it feels like I'm riding a basket ball. They have worn very well but I rotate every 3-5k.
