Nylon wheels are made of plastic (Nylon). PolyStyrene (Plastic)wheels are the ones you mean. (Yokomo's, etc.)
Boiling Nylon makes it SOFTER and more flexible, not more brittle.
Boil at a very low simmer so as not to WARP the wheels from too much heat.
Soaking over night in Acetone will dry the Nylon out and make it more brittle. It will also Ruin the Tires if your trying to save them.
Leave in the Acetone just long enough to dissolve the CA.
I worked in Plastics for almost 15 years, so I should know.
Question: How does one tell which is which.
Answer: Nylon wheels will make a dull "thunk" when tapped on a hard surface. PolyStyrene wheels will a sharp "click" when tapped.
