You be the judge... Below excerpt quoted from Tire Business Dot Com

"The dots on new tires that have them are not critical but are intended to guide technicians when positioning the tire on the rim during the mounting process.

Since it is very hard to make a tire that is perfectly balanced, some tire manufacturers apply yellow dots that indicate the tire's light balance point and serve to help you balance the assembly while mounting the tire. The yellow dots should be aligned with the valve stem on both steel and aluminum wheels since this is the wheel's heavy balance point. This will help minimize the amount of weight needed to balance a tire and wheel assembly. So usually, whenever you see a yellow dot, match it up with the valve stem.

This is always true except in cases where a red dot also appears in the lower sidewall. The red dot indicates the high point for both radial run out and radial force variation. As I'm sure you know, not only is it hard for tire manufacturers to make a perfectly balanced tire, it also is very difficult to make a perfectly round tire"
