    After installing tsportline 20" wheels to replace my Model X slipstreams, I noticed about a 5-10% increase in wh/mi. Tires are the same. It surprises me because the old and new wheels are the same size. For example, my regular route home would take about 330 wh/mi on slipstreams but is now taking 365 wh/mi. It feels like more energy is required to reach the same speeds particularly when accelerating. What is your wh/mi impact on new wheels?

    That's actually an increase in wh/mi or a decrease in efficiency.
    Yes, the weight of the rims can have an effect
    Also, if you have new tires, they are 'stickier' and may use more energy initially
