Going from D's to E's. PSI?

[Stormrider151]

Thanks all for your input. I had the tires installed along with the new bearings. I'm running the tires at 80 psi on the trailer with TPMS. In the process it was discovered that the bearings had little grease in them and a grease cap was never installed. Thank you Lippert and Evergreen. They tried to find a grease cap for it but no go. So I had to order one from Lippert. I really hate doing that because I just really don't like Lippert anything.
