Mazda RX8 wheel rim and tyre ?

This wheel rim and tyre was bought through Mazda to use as a spare wheel as the RX8 had only an puncture repair kit. It has a brand new Bridgestone Tyre, never used size 225/45R18 on a 18" alloy 5 spoke wheel. It will fit into the boot. The tyre at the time cost 185 and as I no longer own the RX8 I have no car that this wheel will fit hence the reason to sell. The rim is also in excellent condition although it was not brand new from Mazda. I think this wheel will also fit the Mazda 6 Sport.
