OK UPDATE......... After utilizing my normal tire removal tools I have decided that unless buyer is willing to pay cost of me having tire shop remove the other three tires they will be local pickup with the tire still on three. The tires are so heavy duty and stiff I almost did not get the 1st one off. Not your average car tire here. Thankfully i broke the bead loose on both sides of the rims while pulling the trailer up close to the garage or we would not even be having this discussion now
After finally getting the tire removed ( three plastic buckets later

) I was able to get the shot you guys have been asking for. It is not on the outside of the rim, it is on the inside as shown.
But I was correct in stating the rim was 11" outside to outside of flange
and there are nubs on the inner portion of the rims 3 per rim that look like they accept dog dish caps. I do not have any 3/4 ton caps here or I would try one
picture of what the back side of the rims look like.

Most women like the strong, silent type… Fortunately for me, my wife prefers the out-of-shape, mouthy type.
