Claim:
A construction vehicle including: a chassis, a first wheel having a first diameter and a second wheel having a second diameter that differs from the first diameter, the first and second wheels supporting the chassis to drive the chassis over the ground, an electronic controller independently controlling the first wheel within a first output control range including a first maximum allowable speed and a first minimum allowable speed, the electronic controller being configured to adjust the first output control range, a first operator input operably coupled to the electronic controller and supported by the chassis, the first operator input being configured to provide a first input to the electronic controller, and an operator interface operably coupled to the electronic controller, the operator interface including: a second operator input, and a software program configured to show a first tracking adjustment number on the second operator input, the software program configured to adjust the first tracking adjustment number based on an operator tracking adjustment input that accounts for the different first and second diameters, the electronic controller receiving the first tracking adjustment number, the first tracking adjustment number being at least one factor in determining the first output control range.
