Spare mounted and ready for action,hehe.
Thanks to Steve Ganz@carson toyota for getting the wheel for me and Brandon@tirerack and Rominl@clublexus on tire advisement. I'm glad that the tirerack's warehouse is only one state away, because it only took one day to get the tire in.
The wheel size is 18x8.5 with a 40 offset and tires are 245/40 18. There is only a small bulge, but it really doesn't matter because i don't use my trunk very much.
