looking to find 1(one) 04-06 SL wheel to be used as a full size spare, honestly I could careless if it has a tire or not (will replace it anyways) Let me, planning a decent/long road trip and want more than a donut (just in case)

 

Go on Rockauto.com and get it from there. Costs about $140? , and they are identical to originals. I bought one 18" for my 04 and it was brand new for only 190 after shipping and taxes. Hope this helps
