Many good points here, I agree the tires must have been low, but I have checked them before I loaded the trailer so the pressure wass fine. I can only guess there was a fast leak of some sort during the trip causing a overflex. As for the wieght, I really doubt it was overloaded, how do I know, I also pull a 22 footer camper that is 3,500lbs and its rated for 5K of combined weight and it didnt feel any heavier then that. The wood was dead elm so its extremely dry, but still great burning firewood. Since its dry elm, I would say it weighs alot less then maple or other hardwoods. I have been shopping for trailer tires and can't seem to find a good price. I was hoping to find matching tires as the date on the tires says 2007. The oringinal tire is towmaster brand.
I have stopped at TSC and they carry carlise (sp?) and load star. Walmart in my area only carrys carlise and I am trying to stay away from it. Does anyone have good online sources they like? I have googled trialer tires and found many. Looks like I might have to bite the bullet and get one at TSC. Does anyone have opinions on load star brands from TSC ?
