Tire cutting?

[Redline it!]

Ok, after frustration with using the search function, I cannot seem to find what I am looking for.
Does anyone have a tool they use to mount rubber tires on (such as those from Aoshima) so you can get nice clean cuts to widen or narrow tires?
Everything I have tried wobbles in my drill too much and I'm tired of messing up tires.

Well, I can only say that I have had luck with using my Dremel. It is a higher RPM tool than a drill but you can preload the speed with your tool or hand easier than a torque laden drill. I use a piece of brass that is so short it mounts right to the top of the collett. Then I pressure fit the wheel and tire on that. I can say that it usually is a 50/50 but after many mistakes my average is getting better for these types of things. Hope this helps?!

Actually, I didn't word that correctly. Your brass piece is more of what I am looking for. Something that will hold the tire in place while spinning. Do you happen to have any pics of it, so I can get an idea.
Thanks for your help Enzo

I don't have a picture readily available, sorry. I could take one, but the wording will describe it. Go to your LHS and look for the K&S metal supplies. Take a wheel with you if you need. I was at my LHS yesterday and saw many thicknesses of rods both aluminum and brass. All you would need is the appropriate thickness to fit in the collett. Then you can adjust the inner wheel diameter by adding strips of paper or something. You might even get lucky and find that the same thickness works for both ends. Heck, even use your drill with the right thickness for the hub. Should work fine. I have even used BBQ skewers in the Dremel with success. Hope this helps?!

Get a wooden dowel or PVC pipe that you can stretch the tire over from your local home improvement store. Get a long blade such as a utility knife or razor blade and the rest should be obvious.

I widened/narrowed a set of the Aoshima TE37 using an aluminum rod chucked in my lathe then used an x-acto as the cutting tool, but it's the same concept with the dowel.

Couldn't you also cut a hole into a board of the same size as the tire or rim that is the depth you need.
Then place the wheel or rim in the hole, and slice everything with a razor saw?

This would cut multiples to exactly the same depth/width.

You wouldn't have to worry about anything wobbling....

Assuming the hole is perpendicular to the face of the board, you can use the board itself as a guide, and have everything come out nice and straight?

Just another way to try....
