I feel foolish. I bought a compact spare tire from the salvage yard. When I went to load it in the spare tire compartment I found I already had a compact spare in there. Oops. Now I have a compact spare (wheel and tire) that I need to unload.
I have a 2006 GS 300 AWD, but the tire came off of an 2006 IS 350. Tire size: T145/70D17 106M. The tire is in my garage in Tulsa, OK. Email me at twhite@citgo.com if you want to discuss.
