Many posts are based on personal conjecture without scientific proof. In addition, there is a lot of anecdotal evidence. As such, there are no scientific conclusions to be made.
Actually, scientific evidence can be based upon the overwhelming weight of evidence, and that evidence clearly shows the over-inflation, just like under-inflation, causes uneven tire wear over the life of the tire. There is absolutely no evidence to the contrary.
BTW, I use no beliefs; I use facts.
