ROI for the wheel and tire combo is more difficult to calculate in the ev world at least. Do you calculate just the energy costs for 0,4€/kwh at fast chargers. With that you get 1500€ investment/0,4=3750kWh-->payback 375000km driven. Not very tempting.

If you have to replace the tires anyhow it drops the costs to half when you just buy new wheels. Payback 187500km already much reasonable. Also you can sell your old wheel bringing the costs down even more. Or if you have a new car and you need second set of wheel anyhow then the aftermarket solution is already cheaper than OEM solution.

If you calculate any value to your time standing at the charger, which was main reason I sold my ID3 where one charging trip was 50 minutes of time wasted. 10 minute drive to charger and 30 minute charge and drive back 10 minutes. Lets here put a hourly rate of minimum 15€/h. To drive 10% longer means you can drive with the same charge amount 18750 more km. With consumption of 14 kwh in real life per 100km that means 428km per charge (60kwh of energy charged) -->43,8 charger visits less-->36,5 hours of you time saved-->547€. Now you can calculate this with your own numbers.

Do these e primacys last more km than the grippier stock size. My guess would yes they do last more. That also impacts the ROI.

However to get the car more silent is priceless or diffucult to put value on that.

Get more comfort/softer ride same thing what you value or want from your car.

Do you start to calculate how much more does it cost to have 10% bigger battery? However more efficient car is faster to drive on longer journeys at least on theory level as you need less energy to load into the battery.

So there is so many things that tire wheel change impacts its not a easy task to say what is the ROI for this change. From 1-5 years is my estimate.

In Teslas minimum Wheel size is about 18". In model 3 you migth be able to fit also 17" but there is more to this story. Here I am talking only the Model 3, but that same size will work also on Model Y and Model S Teslas and most all other evs out there as well. You just need correct offset wheels. In Model S I need to make custom wheels, but that is the case anyhow if I want more aerodynamic wheels.
