Not only is it not just you, it is endemic.
On the subject of spare tires, my wife, I, and our daughter all have Hyundai Sonatas. 04,06,07
The concave spot in the trunk to hold the donut spare is full size. So I bought new rims and tires and put full size spares in all three cars. And it has paid off twice so far. And it is even more critical to do this in a woman’s car.
So I have promised myself that if I buy another car and it has room it’s going to have a full size spare before I drive it off the lot or there will be no deal.
Very wise. Like those Sonatas, huh? I was looking toward a used Camry...
