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.

Bought truck brand new in 2019. Around 16-17,000 miles, I had to replace both front tires, the steel belt had shifted inside the tire causing a bulge and making the vehicle vibrate severly while transporting 3 horses (Approximate trailer w/ horse weight = 14000lbs). I brought back to the dealership, replaced with the same brand as I was unaware of these issues.
