Abstract: Increased tyre wear in electric vehicles is a major concern from an economic and environmental perspective. Changing certain vehicle parameters can help reduce the tyre wear. This paper investigates how tyre wear would vary if the centre of gravity position and drivetrain configuration are changed. To calculate tyre wear, a full-vehicle model and a non-linear brush tyre model is used in conjunction with Reye's wear method. The simulations performed are constant velocity, straight line acceleration and steady-state cornering events. As expected, the results show that equally distributing the vertical load and the driving torque between the front and rear axles gives the lowest wear rate in most scenarios. An increase in acceleration has the dominating effect on wear followed by torque distribution and lastly mass distribution. Torque and mass distribution have a larger effect on tyre wear during the straight line tests than the cornering ones.
