If it's anything like the Policar (poor man's proslot) Ferrari 355, then all I did was hold the end of the plastic stub axle with some pliers and pull the wheel off with a twisting motion.

Hope this helps.

To be honest I was more worried about damaging the wheels than the chassis - that doesn't get touched, unless you slip with the pliers! Ouch!
