Abstract
The present disclosure relates to systems and methods of automatically distributing powertrain demand between tandem drive axles in a tandem drive axle system for balanced tire wear between the tandem drive axles. Examples described herein analyze input signals collected from various vehicle sensors about operating conditions of the front and back tandem drive axles, and automatically bias a distribution of torque demand between the front and back tandem drive axles to correct for asymmetric wear based on known normal wear of the tires under like operating conditions.
