Interesting article. One line caught my attention though.
“He says trailer overloading, not tire quality, leads to ST tire failures.“
Either he doesn’t know what he’s talking about, or the masses here on RV.net don’t. I’d like to see some numbers though. The difference in damage done between bias ply and radial when they do blow is undeniable. Radial damage is often very extensive. Bias ply blowout damage is none. But if bias plies blow far more than radials, there may be something to it. I’ll be staying with bias ply on my boat trailer. I do not want steel belts whipping my boat in case of a blow out.
