Goodyear G114 Tires

I run my G114 at 125psi cold. Interesting story I had over 20,000 miles on the trailer at that time. All five of my original tires have been replaced due to failure. The first one was missing a chunk out of the thread about the size of an ice cream scoop. One was to far gone to tell by the time I found it. Two lost thread and the core remained and still held air. Then I found two with waves in the thread. Anyway the last two was found when I was at Moryde in Elkhart Ind. Went to the Commercial Goodyear dealer and I was not a happy camper. Anyway he told me he had a number of G114 failures and the common denominator was a July 2014 manufacture date. Corporate Goodyear is on board with the 125psi. I run TST monitors, the one that blew the monitor was not on the tire. In for warranty work. The other tires even though half the thread was gone still recorded PSI and temps with no problem. Moral of the story for me is there are good and bad G114s.
