I bought mine off eBay, brand new, the above link is £175, I offered £160 & they accepted, but there’s pre owned space saver wheels & tyres in new condition on there from £90 delivered I’ve seen?
The link shows the correct tyre size you need to purchase…
I purchased a cover off eBay link below, the spare doesn’t take up to much room in the boot or you can cut the foam in the boot to fit wheel into. There are owners on this forum who have done this & looks good. I personally like to keep my foam as it was intended….
