The good news is there is room for it in your car! The PHEVs lose that spare wheel well space under the cargo floor. And none of the Hyundai Tucson Hybrid versions come w/a spare either. That was one (albeit minor) of the reasons that I opted for the Sportage over the Tucson.
There does appear to be room, but I lack the hardware to secure the spare in place. That's why I was hoping to be able to buy the whole kit from Kia - the spare, the jack, the wrench and the hardware to secure it all under the cargo floor.
I started out looking at a Tucson. As I researched, I found that the Sportage Hybrid would give me the best combination of fuel economy and towing capacity. In the end I can't deny that I also though the updated styling of the Sportage looked way cooler than the Tucson.
