I am needing new boat trailer tires. The Maxxis UE 168 developed a knot on the tread which was shaking the pick up at 65mph. There is lots of tread but they are old enough and need to be replaced. My question is for those of you who have had the Goodyear Endurance long enough to know how well they are going to stand up-are you still impressed with them? Most things are good when they are new. I will have to order the Goodyear tires as there are no longer any dealers here who stock Goodyear tires-at least not the Endurance trailer tires. Most are chinese "May Pops". Thanks
