I do have some expertise in balancing, so I think I can answer accurately.
In my past I have used some pretty complex balancing equipment to balance the
air bearing spindles on Diamond Turning Machines for optics production.
I guess I was being a bit too cautious when advising to put in the correct
wheel dimensions. Actually, if the numbers come up 0.00, 0.00, it really
doesn't matter too much how you got there.
The input dimensions help the computer tell the technican how much weight
to put where on the wheel to get to the zero zero point. In reality, I guess,
if he put the wrong dimensions in, it would tell him the wrong solution,
close but not quite right. Then, he would put that wrong solution on, and
spin it again. Since the solution was imperfect, he might have to add more
weight and iterate again to get it to zero zero.
So, the worst case is that you get more than the optimal balance weights.
I wouldn't worry about it too much.
HOWEVER, please make sure that the pressure is correct before balancing,
and use your own gauge. last week at NTW they used a defective gauge and
were going to give me 46psi, instead of 32.
