Using inflation pressures higher then what is listed on the vehicle tire placard: 5 years ago I started cataloging all the issues I found posted on the internet as I came across them. I now have over 4 pages of links just on uneven wear. I also have lots links to other issues as well.
Yes, those would be anecdotal, but so is much of the positive information. Yes, it isn't always clear what pressure is being used - whether you could sort it out as "above placard", or "above Sidewall max" or whatever.
But all these links are at the same level of "anecdotal-ness" (Look, I invented a new word!) as the OP.
I wasn't interested in single cases. I was looking for trends, big picture, repeated reports of the same phenomenon.
Besides, knowing how inflation pressure affects the shape of tires is what I do - and more inflation = rounder tread radius is the way the science works.
So, No, it isn't a myth.
BUT - it is clear that there is more going on that JUST inflation pressure. It is being clouded by other things that also have affects. In other words, while inflation pressure has an affect, it can be negated by other factors - so sometimes the tires will wear evenly, and sometimes not. That's why there is conflicting information and confusion.
