Your rims will work, but if you had wider rims, you could run lower pressures (which would absorb bumps better) but the tires would still handle well.

For a <200 lb adult, fat tires shouldn't need to be inflated much beyond 30 psi, if even that much.
I weigh ~270 and built a motorized bike that weighs ~100 lbs. The wheels are steel Worksmans (cruiser-style rims, about 30mm inside width). The tires are 2.125 Kendas, and the pressures are still only 25/40 PSI front/rear.

The Fat Franks are a nearly-perfect tire.
I just wish Schwalbe would sell them without the printed logo and reflex strips, for those of us wanting to build retro-style bikes.
As it is, if you want them naked you gotta sand the unwanted printing off with a flap-wheel. :|

Ah, I've got to start playing with the pressures more. My previous 2.35s, the Kenda Small Block Eights from the John Tomac series, I ran at 40psi, and sometimes a bit less. I wanted to see if this tire would roll faster.
