Should I mention that traditionally the red spot is the "high" point of

that would be mean.

Hi Sanity Claus,

I appreciate those comments, where, if you have a cite that backs up your
belief system, I think it would be useful to all, as Usenet is designed to
be a potluck picnic where each person adds value where they can.

Without further cites, I'd just note offhand that we have a looooooooong
thread on a.h.r, as I recall, on this topic of exactly what the red and
yellow spots mean, which can be _different_ for each manufacturer (and
which aren't always there).

For example, we've covered that the marks are generally most useful for
brand-new wheels (where the original match mounting marks are still
visible), and we've covered why the light spot is still generally the valve
area (all else being equal, of course), even though there's an "additional"
valve there, simply because the plug of missing steel is generally heavier
than the rubber & brass valve despite the very many old intuitive wives
tales to the contrary.

I'm all about facts, where we've looked at the cites in the past to
conclude that, in the absence of match-mounting marks on the wheel, the
best course for a starting point mount at home is the red spot goes next to
the valve if you have a red spot, and if you have only a yellow spot, as I
recall, it goes opposite the valve (but I'd have to dig up the cites to
doublecheck on that as most tires I've mounted have both the red and yellow
so I only use the red mark as my starting point).

In summary, if you can back up your belief system with a cite, I'll read
it, and if you want, I can dig up cites that back up my belief system since
my belief system is never imaginary - my belief system is _always_ based on
actual facts.

If facts show I need to _change_ my belief system, then I'll change it.
o But at the moment, the facts show the red dot goes next to the valve
(for stock steel wheels, and for most manufacturers' tires)

If you have facts that show otherwise, please cite them so we all benefit
from every post.
