I read this article on MSN and it seems to me they are wrong as to where to put the yellow dot.

Where Are the Paint Dots Placed?
The yellow dots identify where a tire weighs the least — the lightest point on a tire. The yellow dot should be directly across from the valve stem, which is the wheel's heaviest point.
The red dots identify where the tire is flattest — the lowest point on a tire. The red dot should be directly across from the highest point of the wheel, which is usually indicated by a colored dot or a notch on the wheel.
If a tire has a yellow and red dot, the red dot takes precedence when balancing the tire.
Why Are These Tire Dots Important?
The yellow and red dots indicate inconsistencies in a tire's weight, construction and structure, which can cause them to vibrate when spinning. Vibrating, unbalanced tires can negatively affect ride quality, fuel economy and braking effectiveness, among other things. A vibrating tire/wheel assembly makes controlling your vehicle more difficult, especially at high speeds, and can increase stopping distance.
