I work as a mechanic at UPS. We USED to run Goodyear tires in our district up untill 2 months ago.
In My fleet of vehicles I have 2 TP60 trailers used to haul extra package volume to outbound centers. These are Pace 6'X 10' enclosed trailers with a max GWR of around 3,000#. We were going through 3-4 marathons a month on these . These were seldom loaded anywhere near max weight and pulled less than 100 miles round trip per day. Our tires are audited for pressure once a month on these so they are not run under/over inflated.
We switched to Towmaster trailer tires (205 70r st) and haven't had a failure yet. I also run these on My 7200 gvw rated trailer towing cars, trucks, tractor with bushhog etc: and after 3 years of heavy use in the nice hot climate here, they are holding up great.
My 2nd choice would be Michelin or Bridgestone.
I deal with and am friends with several tire dealers and to a man, they refuse to sell or even mount a marathon trailer tire.
