I use the acetone method all the time. It works well on some HPI tires, but Tamiya tires and other HPI tires shrink when the acetone dissolves oil out of the tires. Losi/Vaterra tires just disintegrate into goop when soaked in acetone.

Tamiya wheels are made of ABS plastic instead of nylon, and will dissolve in acetone. HPI wheels are fine though.
