With a narrow rim, you'll need to lower pressure for more rubber on the track. But it will wrinkle/squish and wear out the sidewalls faster, and may "wander" on the top end. Add air pressure, you lose contact patch which defeats the purpose of a wider tire. It may "work", but not as well and as long as with a wider rim.

Get a 9-10" rim if you have enough sidewall clearances in the wheelwell. You can run more pressure and still get a good contact patch, longer wearing tire and more stable.
