In the past and hopefully still, tires were marked at their heavy spot by the manufacturers. The heavy spot was marked near the bead with a white, red, blue, etc. self sticking paper dot about 3/8 inch in diameter. If memory still serves, the dot was intender to be aligned with the valve stem. It could just as easily be aligned opposite of the wheel's heavy spot. Hope this helps.

Thanks to all that contributed. I understand and appreciate the concept of a wheel and tire each having their own imbalance and I recall previous guidance to locate the heaviest portions of the wheel and tire separately, then place them opposite to each other before starting the balancing process. Sounds reasonable and I suppose there are several ways to find the heaviest point on the rim. My question is: how does one find the heaviest point on an unmounted tire? Obviously, if the tire has been poorly designed or fabricated with excessive overlap of plies and tread, balancing will be difficult and require more weights. Ultimately, a buyer would select their tires from a rack full of candidates based on roundness and inherent imbalance. ------------------------ Yahoo!
