If your spare wheel doesn't even mount on the hub - well, there's something's whacked about that.

But my spare is on a cheepo steelie rim that doesn't match the other four.

 

Not sure about 2010, but I had factory alloys on my 2007 and the spare was the same tire as the other 4 but mounted on a steel wheel.

 

Even the Sale's person and the Service Manager told me when i get home to buy a cable or chain to lock my spare tire...Body shop can't prove to me where he got the replacement rim from "I forgot where i got it from"

 

Tell me about it!...And what made it even worse i was so piss off I miss I5 and went on N99 did't even know till we got to Fresno
