I suspect not many here have had the opportunity of mounting and balancing tires. Some of the tire build quality can be judged by out of roundness, side to side run out and the amount of weight required to balance the tire. Ask any good independent tire shop what they see. It might surprise you.

Most every tire has paint marks(yellow, red, or white) that indicate how the tire should be mounted and orientated to the valve stem, etc.
Most "tire installers" who mount the tires have no idea what those marks mean.

That's because the valve hole on the wheel isn't consistently a mark for anything. It's usually randomly drilled.

Yeah, right!!! With all of the sophisticated equipment out there now making wheels, they just randomly drill a hole wherever they want to. If you believe that then you must deal with some very low quality products.

I know of no wheel manufacturer who uses the valve hole as the mark for high point, low point or whatever. I've been in the tire industry for over 40 years and have done consulting work for some wheel manufacturers.

The exception to that is that some vehicle manufacturers specify that the valve hole is supposed to be the wheel low point of runout. But there is no wheel manufacturer who has adopted this across the board (as far as I know.)

If you know of a wheel manufacturer that uses the valve hole for marking purposes, please identify them. Otherwise, I stand by what I wrote.
