Re: tires
SVT,
You can might get them to fit but I don't think your tire guy is going to like you very much. You should check with the tire manufacturer for their minimum rim width recomendation.
I would be looking more at a 10 inch width going that wide, at 9 inches you're pulling the beads in about 2 inches! That's a whole bunch with only a 3.4 inch tall side wall. Even if they do get them on I would be concerned with rim damage from the equipment trying to pull the bead over the wheel.
Good luck and stay safe...
