Aftermarket wheels efficiency hit

[Bluemont]

Just curious what others are seeing for the efficiency loss after adding aftermarket wheels? It is hard to say for sure because it varies so much from many different factors. But I was often doing about 270 wh/mi back and forth to work and now it is looking like about 290-300 wh/mi. So that would be about a 10% hit. Are others seeing similar results? These are a little heavier so I expected it but am curious...

Did you change tire type or wheel/tire width? Primarily city miles or highway?

Performance tires, wider tires, or simply non-low rolling resistance tires can hit efficiency. Wheel weight should affect city efficiency but shouldn't affect highway efficiency very much.

Went to Michelin Pilot 4S tires and they are a bit wider. I drive about 36 miles each way. It technically is considered highway but it isn't unusual about half of it to be like city driving.
