As far as balance goes, I have all of mine checked every 10,000 by my local tire & wheel guru. As the tread wears, the balance changes, no matter whose brand of rubber you are buying.. Every checkup almost always produces an adjustment of the balance. This is a cheap way to save on unnecessary wear and tear on the suspension.
