If I understand that question correctly, you can not put a 16" tire on a 15" rim.
NO. The tire is an inch bigger around than the rim....
Probably not. The rim may not clear the brakes.
Nope. the "15" is the size of your rim. 15". So a tire with a 15" opening wont fit a 16" rim. but you can put larger tires on the 15" rim.
No
It depends on the tire. It could be made for a 15, 16, 17, etc size rim.
You can put a 15" or a 16". You can check with a GM dealer's service center about tire sizes, but the Gran Sport has 16" wheels.
No. A 16" tire must go on a 16" wheel (rim).
