A backup assist system for a vehicle and trailer combination includes a steering system, a camera generating an image of the trailer, and a controller. The controller receives the image and identifying a wheel therein, determines a trailer hitch angle using at least one of an aspect ratio or location of the wheel in the image, and implements a trailer backup mode including using the estimated hitch angle in view of a kinematic model of the vehicle and trailer combination to control the steering system in reversing the trailer along a user-selected path.
