Once you narrow the tire and remove the rubber, what do you use to cut the rim?

If you are talking about narrowing both the rim and rubber, JK plastic rim tires are the easiest to do.
Spin them on your tire cutter and use an X-acto or Zona razor saw.
With a Hudy, I'm not sure if the "pointer" will work with JK plastic rims.

Yeah, I too use an X-acto razor saw, even for metal wheels.

Narrow the wheels unless for clearance?

I usually narrow tires from the inside out. IOW, I leave the wheels alone. This used to be a useful technique for tuning the car until the advent of wonder rubber with all its various compounds.
I am not a doctor, but I played one as a child with the girl next door.

Thanks for the input. Trying to narrow metal (aluminum?) rims, not plastic.

I had a friend who narrowed aluminum hubs using a sharp X-acto knife while spinning on his tire truer. A razor saw blade should work too. I would have used my Unimat.
I intend to live forever! So far, so good.

I've always used an Exacto saw blade to cut the wheel after cutting the rubber with the Hudy.

seems to me that any lathe-like solution that keeps everything round, and square side-to-side will do, as Bill F. and others have said.
I've done 'em on my tire machines (most convenient), right on the car when I had to with an x-acto, and best and most accurate on one of my three various mini-lathes. once I sawed 'em down freehand and then cleaned up the ends with a file and an axle stuck in a borrowed, worn-out electric drill. (Bill, I think that you might have actually been there for that one! remember the 900s vs. the 800 wide euros?)
I think that it all depends on the most appropriate tools that one has on hand when the need arises, as well as your instantaneous skills as an amateur machinist.

During a phone call with Jim, earlier, I mentioned, if he didn't have a razor saw blade handy, he could also use a Dremel with a cutoff disc, while spinning it in his tire cutter.

Speedy, when QCS had the 1/32 scratchbuilt F1 class in the early 2000's with Plafit Cheetahs & Betta bodies, Matt often couldn't get 1/32 rears. Someone was always narrowing up & cutting down 1/24 tires so they could run that night. I do remember the .900 vs .800 eurosport tire controversry, but that class was too quick for me to run. I had my hands full with a GT-12.
