Can you run a 285 on a 9" wheel? That is a bit wide for a narrow wheel, but yes it can be done. However, you can't run 245/40 with 285/40. That's over 5% differential in diameter. VDC is not going to like that. Alternatively, you could run 245/40 with 285/35.
A better solution would be to get some wider wheels.
