That's one of those sizes that's seemed to have fallen out of favor. I was going to say perhaps consider changing your rim size but options don't improve much.. in general the industry has been migrating from 16's to 17's though.
I'd suggest comparing manufacturer's stated tire size instead of relying on the given aspect ratio, similar to how few "33's" actually measure 33-inches. In my experience Toyo and Nitto's typically run truer to size than other companies, Cooper can be a mixed bag, and BFG's tend to run short across the board. That may get you closer to your ideal size.
