A vehicle includes a first wheel, a second wheel, and a controller. The first and second of wheels have first and second tires, respectively. The controller is programmed to receive inputs indicative of tire tread wear of the first and second wheels. The controller is further programmed to, in response to a command to adjust torques of the first and second wheels to first and second desired torque values, respectively, and a difference between a tire tread wear of the first wheel and a tire tread wear of the second wheel exceeding a threshold, adjust the torque of the first electric machine to less than the first desired torque value and adjust the torque of the second electric machine to greater than the second desired torque value.
