Muffin

Bringing up this old thread, as we have a Levorg as our family runaround. After a messy puncture and goo incident, I decided to store the styrofoam and get a proper spare wheel. What wheel should work for the 225/45/18? I see an ET55 7.5 + spigot above in Trawlerman's note, but is there anything else I need to look for? Are the 5x114.3 dimensions that important? I saw this complete Mazda wheel with a tyre. Do you think it will work as a spare? https://www.ebay.co.uk/itm/316268545909
