The Renegade offers two spare tire options in the U.S.: full-size temporary use temporary use spare, and full-size spare tire with matching wheel. Without either of those option boxes checked, you get no spare and a flat tire kit (compressor and goo).
The compressor and goo kit is from "Fix and Go". Their own website is fixandgo.com (It comes nestled into a giant foam space filler that would otherwise be the mini-spare tire.)
They put a lot of emphasis debunking the myths regarding fix-it kits, but as it mentions on their site:
http://www.fixandgo.com/debunking-the-myths#toggle-id-4
"It will not repair a sliced or cut tire."
They also fail to mention it will not repair a tire that has been driven too long while flat. Or a tire that has come off the rim. Or a tire punctured by rebar, or "tire shredders", or a bent rim, or a bald tire....
In fact, it will do a bang up job on pretty much anything that would barely be called "tire failure".
I know tires - I've run through 11 spare tires driving a Fiat to Mongolia and on that one trip experienced pretty much every failure imaginable. What came in most useful? A decent plug style kit, a small inflator, another spare tire and practice changing the tire when you're not under pressure. Often you can plug the tire still on the car.
Should you have a little fix-it kit. Yes - it will beat the hassle of changing a tire that can limp home (it needs to be a late model kit without foam that won't damage the TPMS). Should you have a spare? Yes. Should you have a full size spare?? If you often travel to places without cell signal, offroad in general, long distance / cross country or in the middle of the night, in an important hurry anywhere, and many other reasons, then yes, a full sized spare. Well, I do like to be prepared.
