2. David, how are your new tires doing?
3. lindalees818 mentioned E tires. Should I try to find E load?
4. Anyone else have any suggestions or recommendations?
As has been mentioned in this thread, there are very few choices in the ST 13 inch Load Range D tires. My 2014 A122 uses ST185/80R13 Load Range D, which have a slightly higher load rating than the 175s you have. I have not found any manufacturer for the 185s besides the OEM Westlake.
So far, the OEM Westlakes have given good service on my A122. We've gone from Colorado Springs to Lincoln, Nebraska twice at 65-68 MPH without any issues. Also, trips up and down the Front Range, and one over to Ridgway and Telluride. Total of about 4,500 miles.
I very much doubt you will find a Load Range E in an ST 13 inch tire.
Because of the difficulty of finding replacement tires, and the costs of breaking down on the road, I make sure I take care of the tires. Tires (including spare) are aired to max sidewall pressure (plus 2-3lbs if I am going to significantly lower altitude or significantly cooler temps). I ensure I am well under the GVWR for my A-frame. Typical tow weights are 2700-2800lbs (depends on water carried); GVWR is 3100lbs. And I keep my speed under 68 except to pass on the Interstate. Finally, my A-frame stores in the garage where it is protected from UV when not in use.
