Yes you can rotate front to back. Thats the way to rotate them on our cars...
It still looked like the spare was smaller in height than the normal tires....
I asked one of my friends who owns a shop about this and he said it wouldnt hurt anything as long as the tires the same height.
Course I remember my other mechanic friend with an LS1 who put his spare tire on the front and put the front on on the back to get home.. He could rebuild an engine with a tooth pick.
Its like half the people are split on it in here and in camaroz28.com. But the argument seems to be stronger for putting it on the back. Makes more sense to me.
