Load & Inflation Guide

My 2008 came with BF Goodrich Rugged Trail T/A 245 75 R17/E all terrain tires and I went to their website to look for a load & inflation guide so I caould figure out the proper pressure to run when empty as to not bounce all over the road and also what to air the tires up to when I was pulling my fiver. Does anybody know where to find that? Goodyear has the good sense to post this on their website.
