Your blowout occurred due to inferior Chinese/Asian manufactured trailer TIRES!
There are NO trailer tires currently manufactured in the USA and there has not been any for years. All currently available trailer tires for sale
in the USA are manufactured overseas somewhere. This includes Goodyear Marathon tires.
This PROBLEM with offshore tire blowouts is so widespread that Jayco has entered into an agreement with Goodyear to exclusively install special Goodyear Trailer tires on their RV vehicles that Goodyear will NOW manufacture in the USA.
There will be ONE exclusive Goodyear tire dealer for these Goodyear tires supplied to Jayco however no information if these USA made Goodyear trailer tires will be available for purchase by the general public. This is the first time in many years that a trailer tire will be manufactured in the USA.
"I" now always install on my trailers "LT" or light
truck tires in the appropriate size if available and suggest to anyone else they do the same. Since doing this per the "suggestion" from the Motorsports Director at one the major US tires companies I have never had a blowout or tire issue arise on any of my trailers. This includes all my trailers from a 40 foot triple axle
trailer down to an light
fiberglass RV trailer.
Prior to this "suggestion" I also had many trailer tire failures when running trailer tires of any brand on a trailer. On one trip Nashville to Dallas in 2010 with my 40 foot 2 car triple axle
trailer loaded with only 1 car on the trailer I had 3, count em 3, Goodyear Marathon tires blow out all less than 3 months old with less than 1,000 miles. I arrived in Dallas at Mecum auction with tires on the front and rear axle
and no tires on the middle axle. Good thing I had a spare tire and well built trailer!
Goodyear tires solution to this problem was to have me return to them the blown tires for inspection. Upon inspection their offer was not to replace the tires but a complete full refund for the full set of 7 tires as long as I signed a "Release of Further Liability" statement. Minor damage to the trailer that I did no receive compensation for damage. Makes you wonder what they know about their own overseas made tires????
I have since run USA manufactured "LT" light
truck tires on this trailer and all my other trailers and have have never had a tire failure since on any trailer and this includes the triple axle 2 car trailer has been pulled "Coast to Coast" numerous times since that Dallas trip fiasco!
