Thanks for sharing this. I like to blend a bit of both form and function. I'll likely never track my car, but I can expect to take it canyon carving occasionally, and overall want to maintain its oem driving dynamics feel. So while I know any mods in the wheels and tires can affect driving dynamics, i'm looking to maximize range while also having a more flush look in the rears without having to add spacers.I can say without a doubt tire compound matters the most for efficiency below 70 mph. I have done extensive testing on this with different size diameter and width wheels/tires. Changing dimensions does make a difference. However, switching to the Hankook iON EVO AS tires alone made the biggest difference.
I have tested a RWD with 18" Aeros on my 25 mile test loop and it did 191 wh/mi. However, I was able to do 194 wh/mi with my 2022 Model 3 Performance on the same loop with the same 59.9 mph GPS measured average speed with 235/35/20 Hankook iON EVO AS tires.
To be able to match RWD 18" Aero efficiency with 20" Aero wheels on a Model 3 Performance is game changing. With a new 82.1 kWh(79 kWh usable) battery I am looking at 400+ miles of range at 60 mph. Even at 70+ mph I could achieve about 340 miles of range. I even did 299 miles on non Aero 18" wheels and summer tires on my Model 3 Performance once.
Switching tires is critical for someone who lives in a colder snowy climate and needs to go on 330+ mile commutes and still wants some wheels and tires for the track a few times a month. The stock wheels and tires will be my track setup. The All season tires will be my long commute tires.
So i'm thinking i'll stick with the oem 20s, and eventually change it out to 19s. I personally think 19s provides the best benefits of range and form. So I have the Hankook ION EVO AS tires on my radar now. I also plan to lower mine ever so slight by another half inch. So i'm waiting for aftermarket options that will be compatible with the electronic dampers on this car.
