Cannot find the correct tire size in the drop-down. But these tires are Bridgestone Dueler H/T 265/60/20 685. These tires are extremely unstable on this vehicle going any rate of speed on the highway with rigid surface. The vehicle sways back-and-forth as if it was on ice and has a little to no control road conditions are clear when this happens. Even worse when it rains I want to take the vehicle on the highway. I believe due to the gap of the tread pattern. They are catching on the grooves and throw the vehicle back-and-forth dangerously. I had also had a trailer that weighed an estimate of 8500 pounds with the tires, and was worse as the trailer would fishtail tire pressure is at factory recommendation as well. These tires need to be reevaluated and does not belong on this type of vehicle. There are no warning lamps that come on other than a very unstable ride. My vehicle was involved in an accident due to a driver swerving directly into our lane on the highway as a result of trying to gain control. The tires were very unstable, and did not have control as a result of trying to gain control on the passenger side of my truck I slid in the concrete barrier when trying to correct the steering.
