I can't believe this is really even a thread...it made me laugh. I think your problem is with you not rotating your tires and not the spare being a "temp". The spare isn't intended to be a swap out savior....if that makes any sense. Its to get you back on the road so you can fix your issue...not prolong it.

But to add to it...My SRT-4 ACR did have a track ready 15" spare tire on it close to the original 16". The non-ACRs only had a true temp wheel. It was to help not ruin your day at the track and also worked better for the lowered Tokico struts.
