It should be, but it also depends on how it is rotated. I am finding many centers are doing parallel rotations rather than cross rotations. So a problem could stay on one side, and quite possibly more on one tire, depending on the condition of the tire being able to tolerate the 'abuse' compared to the other one.
Point to consider: My mom was asking me if I knew of a place to get a reliable 4-wheel alignment. Her mechanic she likes and trusts informed her that Goodyear and I think Bridgestone are prone to get out of balance and become sensitive to alignment, and thus should be rotated every 3-4K. Michelins don't seem to have this problem and don't need rotations as frequent.
Her mechanic doesn't do alignments though, and the 2 shops he used to refer his clients to have lately been a hit or miss, so he no longer has a recommendation, which is why my mom asked me. I guess he never had to have any of his own cars aligned.
She thought of the body shop that I trust that's near me. I only used them for body work, and once for an oil leak problem that was spotted while body work was done.
I mentioned that I had a goodyear dealership check my alignment, and they goofed in reporting a bad front toe. The combined toe was dead-on zero, so either they got fooled by the dash and had the steering wheel off center, or the steering is indeed a bit off. One rear wheel though was off on one of the specs, but I decided to leave it alone.
