I went to the GoodYear Commercial Tire center located in Tampa FL. I took both tires and showed them to Brian, a professionally trained GoodYear tire expert. He explained in more detail than I could comprehend, the construction of the tires and how they are tested and testing results. I quickly realized I was not talking to a tire dealer that happened to sell GoodYear as one of their many products.
Bottom line according to Brian; pressure required 125# is was running on 110#.
All of the abnormalities, river ware and cupping have been caused by low pressure. Brian examined the tires and said all indications are the tires are running true and don't appear to be dealing with any suspension problems.
During this whole process I have been in contact with MorRyde. Brian at MorRyde, yes there are two Brian's, has been extremely helpful with recommendations including checking my bearings, which I did.
Hope this helps.
