Just to clarify I never said hear say is necessarily bad or we shouldn't accept it. We just have to remember when making a decision that hear say isn't necessarily fact and may be based on incorrect, biased and false information. We all use hear say when making certain decisions, we just have to use a little caution, a little common sense, and what ever knowledge we can gather. Not trying to argue with you bruceb58, just expressing my opinions. My whole point is that most of us know little about trailer tire difference and we therefore rely on what we hear from others. In any event I hope the op finds a quality set of trailer tires and has thousands of miles of uneventful towing.
