The bulk of the energy reaching the tires is spent on two things: Drag and tires rolling resistance. Aptera is a marvel of engineering when it comes to the coefficient of Drag. So, most of the energy will theoretically be spent on overcoming tires rolling resistance. I believe Aptera deserves a serious effort devoted to developing specifically designed tires especially that the vehicle is light but most importantly that it is a three wheeler. Regardless of the fact that steering and suspension are kept as is, there may be a favorable improvement. I did not come across much in the literature that applies to such a case.
