E load tire pressures for daily use and how I came to it.

I just got finished setting up my new TPMS on my Suburban tonight. Door jam says 50 PSI front, 80 rear. So that's what I put them at. Did some Googling and some people go with the door jam, others don't. We're headed to Wyoming next week on a trip (not towing anything) and I plan on keeping the PSI where it's at...mostly because that's what the door jam says.

But now after reading this I'm reconsidering...
