Your new tire will have no wear compared to the existing tire which will have wear. If the existing tire was worn by more than 1/32 difference then you might experience issues due to the slight difference in circumference between the two tires. Note that the manual suggests that if you blow out a rear tire and have to use the spare that the front tire is moved to the rear and the spare is put on the front for this very reason.
I can say that I ran 4/32 on one side and 3/32 on the other with no problem during an autocross event once but I imagine a situation if you're running much more than that like 5/32 one side and 9/32 the other can cause funny lock ups in the diff which is what I think might be happening to you.
