If you see both a red as well as a yellow dot on the tire, the red dot takes priority. An easy way to remember this is the phrase “Red Rules.” Ignore the yellow dot and match the red dot to the wheel low point dimple as some vehicle manufacturers do or, if no dimple is marked on the wheel, align the red dot with the valve stem.
I can't find the link right this minute, but I've read that Japanese manufacturers just place the tire stem on that spot rather than marking the rim with a dimple.
Either way, same principle applies: trying to match the tire and rim during mounting to remove any undesirable vibration or hop.
