Hi Dave-this really isn't the forum to get info on 'newer' Shelbys. The 2007 SGT came from the factory with the tire inflator kit and the inflator canisters are no longer available. You can get a full size spare, but I believe some have had an issue with it not fitting correctly in the tire well as the particle board cover will not fit flush. I just carry an aftermkt 'inflate a spare' cannister. Best to check Team Shelby site.
