General Motors2015 colorado spare tire

I recently purchased a 2015 Chevy Colorado Z71 on Jan 24, 2016
The pickup did not have a trailer hitch, so I got an after market receiver hitch and put it on myself. I had to lower and remove the spare tire. Upon doing that, I realized the spare tire is not the same size as the other tires on the vehicle. Tires on the ground are 655 65R 17. The spare tire is a 665 70R 16. At first I thought someone might have swapped them, but on the sticker inside the driver side door says that is what is there. What genius at GM made this decision? The spare is wider, and a good 3/4 inch taller than the others. There is no way I would drive with this tire. The difference in size will wreck a transfer case, and really screw a limited slip rear end. I have been looking for several weeks to find an appropriate wheel for a spare, but I really think it should be up to GM to replace it, so the spare tire is the same size as the other four on the vehicle.
