Quiz of the day

We picked up our Neuvo yesterday and have spent today reading through all the helpful stuff that came in a very nice A/S bag............sorry, having trouble typing as my nose is growing at an alarming rate .  Anyway, despite a great handover, our salesperson had no idea what an object was for and we are no wiser either.  I know it's bound to be something obvious but, right now the obvious bit is eluding us.  It's a circular metal plate about 14cms in diameter with a hole in the centre.  It has 3 nuts welded to it and came with 3 matching bolts, all wrapped nicely in a grey cloth bag. Anybody got an idea what it is?

I haven't got such a thing but I believe it's to do with your spare wheel (assuming you have one)

Paul, thanks very much for coming back so quickly with that.  Yes, we apparently have a spare wheel somewhere, finding that will my fun for another day.  The explanation makes complete sense, although it would have even better if it had a little note of description attached.  I agree with the posters in the link, if needed it would more sensible to stick the wheel in the van to get whatever remedy was required.

Thanks again.
