A Quick Disassembly Question

I usually take my figures apart when I paint them but I have run into a slight problem. I'm turning a ROTF Swerve into Sunstreaker. Behind Swerve's front wheels, you can see that red disc attached to it. I want to change that red behind the wheels to yellow without having to paint through the wheel itself.
Taking Swerve apart the disc is part of the wheel assembly. Is there any way to physically take the wheel off without causing too much damage? Is there any surefire way to remove any wheels that are attached the same way, or do I just cut the metal and have non-functioning wheels?
*Edit*
I already know the trick about using a hammer and small nail to removee the normal metal pins, but there is no way to do this with this mold. Any help would be greatly appreciated.
