Spare Tire ?s

After nearly 14 years I decided I should probably check to see if I have a spare tire in the GT. I removed everything from the trunk (10' X 10' canopy, bag chairs, tool box, fluids containers, jumper cables, scissor jacks, 2" X 4", etc...), pulled the trunk mat, removed the spare tire card and found this:

I thought for sure it would be a full-size spare.

Now for my questions:
Would you guys trust/use this temporary spare (50 MPH max)?
2nd will this fit my 5 on 4" small bolt pattern axles?

Thoughts please.
