As far as balancing goes, here is an email I got from Cooper. I did not see any dots on my tires at all, though I have seen them on other brands.
"You may see a red dot on some tires manufactured. The red dots are located at the 'high point' for radial run out.
You may also notice a yellow dot. Yellow dots on tires can be used by dealers to help match-mount tires to rims. The yellow dot should be aligned with the valve stem on both steel and aluminum wheels since this is the wheel's heavy balance point. This helps to minimize the amount of weight needed to balance a tire and wheel assembly. Although this marking is used to initially line up the valve stem to start the match mounting procedure, the yellow dot does not necessarily end up matched after the weights are added, it is a 'starting point' only.
Please note that on wheels that have TPMS sensors on the valve stems it might be a good idea to spot the yellow high point dot 180° from the valve stem for the lowest balancing weight.
Certain conditions, like a tire being out of round, are covered during the first 2/32nds of tread wear. If a tire is manufactured ‘out of round’ it is an adjustable condition and is covered under warranty. If you feel that you have an out of round tire, please return to your dealer to have them replace the tire under warranty."
