theyre just to help the tyre manufacturers out, basically a sort of way of categorising the tyres when theyre on the rack they eventually wear off and are a good thing to look out for when buying second hand wheel/tyres, if theyre still there youre onto a winner! >>
If the dots your talking about are either red or yellow, and appear on the side wall.
the dot 'should' be aligned up with the vavle. it is the manufactures indication of ballance taking into consideration the valve. This i guess would be the same in the states as it is in the uk

yeah they're just a way of showing the high point and the low point of the tire. I learned this stuff cus i mount tires for a living. Turbotone was correct in saying the tire mounter has to line up the dot (the yellow one) with the valve. Then when you balance the tire u get a better and more accurate reading on the balncer. That's all it is, it comes off over time.
