Trimming of tire ID to fit Palmoz wheel

[AJM]

My first post -- I am starting a new project, building a 2013 60th anniversary Corvette. Just acquired a set of Cup Wheels from Gravity Colors(Palmoz 1/25 wheels) and the directions state to 'trim .5mm' from the ID of the donner kit( Corvette ZR1,Revell). My concern is how to do this in the most effective way, without having a 'jagged' cut line. 

I'm thinking about using a compass or circle template to measure and draw the .5mm cut line and then use a very sharp xacto blade and try to cut out cleanly. Want to know if you have any advice on the best way to do this.

appreciate any help,

.5mm (one half of one millimeter) isn't much at all. Trying to mark it on the tire will be an exercise in frustration.

For such a small amount of material removal, i'd use a round object (like a wooden dowel) with sandpaper (180 grit, wet) attached, and twist it in the hole until you get a good (slightly tight) fit with the new wheel. Then sand the edge of the opening very smooth with 600 grit wet, the same way.

Work slowly and carefully so you don't take too much material out and ruin a tire.

Thx for the quick response and advice. After I posted this and thinking about it, I realized that trying to sand it with a dowel may be the best approach.
