Most tire manufacturers still put a yellow paint mark on the tire that is supposed to be aligned with the valve stem. This is the lightest part of the tire. …….
ah ….. Mmmmm ….. not exactly.
First, the mark is usually red - AND - it's the high point of uniformity (think roundness and you'll be close), not balance.
Second, the vast majority of wheels are NOT marked for the low or light point with the valve stem. With a few exceptions, the placement of the valve hole is random.
Yeah, I know, that is NOT what the Yokohama web page says, but they are wrong. Last year I did a survey of OE manufacturers and found only one (Chrysler) who match mounted using the valve hole and it was for uniformity, not balance. No one else specified the location of the valve hole - and since, by far, the vast majority of wheels come as OE on new vehicles (meaning the aftermarket replacement of wheels is by comparison pretty small), what Yoko said wasn't true.
HOWEVER, there is no harm done matching tire dots to the wheel valve hole - only it more than likely doesn't do anything of value.
