2018 Ram 3500: tire blowout or tread separation

Filed Jan 29, 2026 · Tires · SC

Trailer King RST 235/80R16: six of them on a triple axle boat trailer. Was towing a boat and experienced a blowout on the passenger rear trailer tire, of which we did not hit a pothole or strike debris. It bent the boat trailer fender and damaged several components of the trailer. It was identified by Discount Tire that the passenger side lead tire experienced belt separation, which is a manufacturer defect and was most likely the cause of the passenger side rear trailer tire to blow out and cause excessive damage to the trailer. There are numerous other customers of this tire who experienced significant blowouts on their trailer, which poses a safety risk to all who own trailers with these Trailer King RST tires and those who travel the roads with them. The belt separation was confirmed by a third-party tire shop recognized nationally. I submitted a claim for the blown out tire with the company manufacturer, and they claim it was not due to manufacturer defect. Unicorn tire does not accept responsibility for the manufacturer defect, even though it was confirmed by the company discount tire. These trailer tires are unsafe. Bottom line: two of six trailer tires that were two years old and had less than 3000 miles on them experienced belt separation, one of which had a significant blowout that could’ve caused serious accidents. This is not an isolated case as other reviews have shown these tires to be unreliable and unsafe disregard the VIN associated with this complaint as it would not accept my trailer VIN.
