I had the center belts break on a tire, on our less than a year old 5er. I caught it before any damage was caused while checking the tires noticed it was balloned out in the center. I called tow max and they have a 5 year warranty on defects and they shipped a new tire to my tire dealer at no charge, they just wanted the old tire back. Also said if you have a blow out or any problems with a tire to keep the old tire and call them if less than 5 years old and if any damage to the trailer from a blow out that they will cover it if from a defect in the tire. Anyone with problems should call them direct.
