I made 2 trips between Southern CA and Las Vegas. Once using the factory AeroSport wheels and tires (without inserts) and another trip the following month using the new wheels and tries. The battery charged to exactly 411 miles at 100% for each trip.
The resulting mi/kWh for both trips were virtually the same. So with regards to mileage, I don't think the new wheels and tires made a noticeable impact. I'm sure that on paper, the factory wheels and tires would produce better calculated efficiency. But in real world driving, driving style/technique has a greater impact to efficiency.
Looking at my cars stats below, I would say roughly half the total miles shown in trip B were on the new wheels and tires. I've never reset Trip A or Trip B since I took delivery in December 2023. I find can also easily get around 3.00 mi/kWh by changing my driving habits but I didn't purchase a GT-P to drive like that.

At the end of the day, just drive the car as you would an ICE car ... and enjoy it.
