Tire Markings

If you look at the sidewall on this passenger car tire there's a yellow dot At 12 and there's a red dot at 2. I'm pretty sure I remember being told once that those colored dots on the side walls on passenger tires are there because if you align the dot with the valve stem it will facilitate the least amount of wheel weight necessary to balance the tire. That doesn't explain two dots on the same side wall or the different colors. Does anybody out there have any information and can help clear this up for me?

Yellow is tire sensor position and red is a rough/low spot in the tire

Where did u find that info? The red or the yellow gets lined up with the valve stem or no?

Thanks. The explanation still has me a bit unsure but thanks. In any event the guy who mounted the one in the photo didn't get it right neither dots lineup with the valve stem.

Sumatomo Truck tires had a green dot as a balance marker to line up the valve stem. but that was 40 years ago and most tire guys had no odea what it was for.

At least it isn't under inflated like some tires I know!
