I'm having a clearout & have a new & unused genuine space-saver wheel & tyre, that can with a CL203. The tyre is marked Vredestein 165-15 & has to be inflated before use so as to make it compatible with the other three 17" wheels on the car, I also have the bolts for the steel wheel unused in a mercedes marked plastic sleeve. I believe the wheel may be used on other cars with a similar stud pattern Does anyone know if this a value?.
