How much does a genuine Superb 18" alloy wheel cost and will it fit in the spare wheel bay?

This is about the going rate

 

Yes it will fit in the spare wheel well, BUT if you do not have the variable boot floor then a 225 may lift the carpet up a little.

Wots a variable boot floor, Martin?

Its a false floor that sits about 4” higher than the carpet that goes over the spare wheel well.

 

It enables a flat load level on the estate (it would also do the same on the twin hatch IF the rear seats folded flat! ... which they don’t)

Thank you Gismo.

 

I've only had my Superb a couple of days.  The only downside I find is that the seats are no way as comfortable as those in my V70 Volvo p/exd for the Superb..  I guess I will get used to them soon however.  I find the Superb handles beautifully and pulls away effortlessly with only 170hp.  My Volvo had 185hp and felt a little slower..  

 

I don't think my Superb has the variable boot floor.  Can this be retro-fitted?
