No they do not always mark a mounting location.Easy physics.
MPH is zero. Top of tire is considered 2xMPH
The question is, however, whether or not the surface speed changes.
P.S. The red dot and yellow dot have a purpose. They tell the installer where to mount the tire in relation to the valve stem.
I ask what to do with the white dot, what to do with the the location when you have more than one dot in different locations and color combinations or no dot.
Unless manufactures specify its generally of little use
Forgot to add that unless you know the runout of the rim. Where the heavy and high spot of the rim is the dots are a bit “useless”
Used to be rumored the valve stem hole would be located at the “low” spot on the rim. After years of spinning up tired on a hunter road force balancer that can do bare rim run out , then locate the high and low spots of a tires and calculated the best mounting orientation …..the dots and valve stems dont align very often.
Plus some manufactured dont use any marks.
