Yellow and red paint spots on tire sidewalls
Recently I purchased a set of tires via mail order and I am about to mount and balance them. On each tire there is a yellow dot and a red dot approximately 1/3 of the way around the tire from the yellow dot in the clockwise direction, and these markings are only found on one sidewall. There is no consistency among the four tires regarding the placement of these dots relative to the molded-in tire markings, which leads me to suspect that they mean something in terms of balance and/or suggested orientation on the rim. The tires in question are Falken Ziex ZE512's in 225/50R17 94V size, unidirectional and symmetrical with a largish circumferential groove in the center of the tread.
I should add that my wheels (Nissan Maxima alloys) each have one small white paint dot near the outer diameter, and these are not located in any consistent fashion with respect to the valve stem hole.
Exactly what do these paint dots represent and how would I best use that information?
Thanks in advance.
