It seems no one can give a definite answer to my question, but I thank all of you for your posts! It was encouraging to hear a few others say they are using an E tire on similar wheels as mine.
I contacted southwest tire/wheel, per JIMNLIN's suggestion. I am waiting to hear from them, after asking if I can mount a 225/75/15 E-rated tire, on their white spoke wheel that is rated 2,600 lb max wt, which is same as mine. I asked if I can inflate to 80 psi, allowing the tire max of 2,830, but never reaching even 2,500 lbs actual wt on any wheel.
I will post their answer, if I get one.
