I professionally mount and balance tires. The dots you speak of are just to help with the balancing by helping eliminate some of the weight you will need to balance(they designate the light spot). Sometimes it will balance out perfect, but usually it will require some weight. If you balance the tire and its around 2.5oz -3.0oz I would spin the tire 180deg and retry. Michelins do not have them. Bridgestone, dunlop, shinko, metzeler, pirelli do. If your going to put on new tires, spend the little bit extra and just get them balanced. Dynabeads are roughly the same price as balancing in most cases so its a toss up. I dont use them but some people swear by em....... JUST BALANCE YOUR TIRES ONE WAY OR THE OTHER.......lol...raise your hand if you like tank slappers!
