BITD, manufacturers used to put a paint dot on a tire's heavy spot, meant to mount opposite of the valve stem. I had a vibration once on my Alfa, turns out they mounted the dot next to the stem. From what I understand, they've gotten away from that. With 5 cars, I'm a regular at my Discout Tire Shop (6 winter/summer swaps per year)
Ever since, when I have new tires for the Beck and the Porsche done, I tell them I want my tires balanced to 12Omph.
