1. A method for providing balanced tire wear between tandem drive axles, comprising:
receiving sensor input about an operating condition of a front axle and a rear axle of a tandem drive axle assembly of a vehicle;
determining a balanced tire wear torque bias factor based on the operating condition;
receiving a driver accelerator pedal request;
calculating a torque request corresponding to an amount of torque to propel the vehicle based on the driver accelerator pedal request;
determining a distribution of the torque request between the front axle and the rear axle;
biasing the distribution based on the balanced tire wear torque bias factor; and
requesting a biased amount of torque from the front axle and a biased amount of torque from the rear axle based on the biased distribution.
