I'm curious about why the diameter is so specific.
I don't know the answer to your question, but since the diameter seems to be important, I thought I'd list a few sizes that are within 0.5" of 28" tall. I just calculated these. I didn't double-check to see that there are actual tires available in these sizes.
245/60-15: 27.5"
255/65-15: 28.1"
265/60-15: 27.5"
275/60-15: 28"
285/60-15: 28.5"
295/55-15: 27.8"
Just a guess, but I think you'll be looking at the 275/60, and maybe rears only.
