Abstract
Methods and apparatus are provided for evaluating tread depth on at least one tire. One or more laser scanners are positioned at an offset position from a tire path of the at least one tire. A profile of the at least one tire is obtained and the tread depth is determined from the profile. Additional information, such as identifying information and mileage information, can optionally be obtained from the at least one tire.
