Honestly, my exhaust is too loud to notice any tire noise, so I can't really give you an answer about that. I'd say a 265 would work on a 9" wheel. I have a 245 on my 18x9 wheels and they don't look stretched, but they still don't quite fit right. The 285 looks perfect though.
Here's a couple pics that show the tire size on the wheel. You can see the lip sticks out farther than the sidewall on the front tires, but the rears are perfect.
