You need to make a measurement to verify that what you’re thinking is actually correct. But like has been said above, there’s no adjustment anyway.
I think you could make a valid measurement using a two or three foot-long carpenter level. What I would do is first use the level determine if the surface that I think is flat is actually flat in the sense of being level. If it’s not level then chances are the appearance of the angle the tires have will make one look tilted more than the other.
If the surface is flat (level) you could hold the carpenters level against either the top or bottom of the tire, and measure the distance between the edge of the level and the tire. If you did this on both sides you could compare the measurement and see if there actually is a difference.
All this would be for naught though, since there’s no way to adjust it…
So yes you probably are obsessing, but that’s something I can relate to…
