Spare Wheel For Astra OPC/VXR?

[Garret C]

I’m looking to get a suitable spare wheel(temporary use only) for my astra that will actually fit in the boot, does anyone know what’s the smallest wheel size that can be fitted to the car without damaging it. Will the standard 17" 5 spoke for the SRi do? Any help would be greatly appreciated.

[R20 VXR]

I've seen a thread elsewhere that suggested a 17" alloy off the Astra Design (same style as 19's) ...and not much more than £150 with tyre! If you get that deal let me know and I'll follow you.
