Finally have a Maxxis issue!

I got the Duro's by chance years ago and used them on a Heavy Utility trailer that used to blow through trailer tires every three years.. I had the Duro's on one side and went through many sets on the other side, and never had to replace the Duros..So from my experience from that, I will definatly will go with Duro's when my factory Lance 1685's tires get old/bad...I never Covered the Duro's either, Also, you could tell by the way the sidewall was molded into the tread pattern was seemless and almost one piece.. Where as all other trailer tires ive seen have a separate tread on top of the tire that's glued on or something and can separate like that one set of unnamed trailer tires did..
