295's on 9" wheels?

[CamaroPat]

I'm considering 295's in the back, 275's in the front and I'm probably going to be using 17x9 wheels. I know the 275's will fit on my '81 Camaro. Is it wise to run 295's on 9" wide wheels, though? The aspect ratio will be 40. Is this too wide a tire with too short a sidewall to be worth using on a 9" rim? Some companies say it's fine and others don't when I use their compatibility guides and calculators. Just wondering what the maximum tire width for 9" wheel is. Thanks.
