The truck came with Continental tires (Model: Conti Hybrid HD3) installed on all six tires (Dual rear wheels). The manufacture tire specification states that the tire is designed to only be installed on the Drive Axle (rear axle). I have been experiencing a steering issue (constant steering wheel correction). This seems to be caused by the tires reacting to any roadway surface anomaly (the tires seem to catch an edge which causes the vehicle to abruptly steer to one side or the other). I tow a 5th wheel RV and the abrupt steering change causes a sever lateral back and forth movement of the trailer when it occurs. This has caused the trailer to leave my traffic lane. I have ensured the air pressure is per the Ford vehicle specification. I am making arrangements to have the steering system inspected and have the alignment checked. I did contact Ford's customer service and asked if the installation of drive axle tires on the steering axle was their intention. The response from Ford's customer service was that the truck was produced with the same tires on all six wheels. I am concerned that the tire may be contributing to the steering issue I am having and may be indicative of a steering safety issue. This has been occurring since we purchased the vehicle on March 21, 2022. The vehicle had approximately 50 miles on it when it was purchased. The vehicle had approximately 1400 miles when we starting using it to tow our RV. The vehicle currently has approximately 4100 miles on it.
