I've followed the thought processes about the RV owners who are to blame for tire failures. While this may be true in cases, to use this as a continuing rationale for TowMax tire blow-outs & failures insults the intelligence of careful, thoughtful owners.
You're not the problem, these tires are no matter what others may espouse as truth
To say that because you clipped a curb or hit a pothole, and therefore you are to blame is just ludicrous. Every tire on the market has to endure these types of road hazards. Not to say that you shouldn't strive not to do so, but it is going to happen on occasion. I know I have clipped a curb a couple times with my Ribs, when a car cut me off part way through my turn. I hated it and I remember exactly where I was both times it happened. So far they have not bubbled or blown. I assume that I am not alone here, but I do meticulously check tire pressure, use a TPMS, and perform visual inspections at every stop and have the tires rotated and balanced regularly.
