I'm considering a used M3 and it has the 19" sport wheels. How much efficiency loss can I expect between those and 18" aeros?

Several studies have shown 5%. I have the 18” and would definitely do it again. The 18” are also cheaper and I hear they last longer as well.
How long do your 19” last? I got 33,000 on my 18” tires.
The first set lasted 33,000 the second set looks great after 8. Note that is on the Model 3 NOT the tire manufacturer’s claim. The Model 3 eats tires compared to most cars. Circle back when you have driven your 19” 40,000 actual miles on your Model 3.
Wow! That's a great chart. Thanks for the info.The efficiency differences with any setup are primarily due to the tire, not the wheel. The wheel itself accounts for a minimal difference (~1% no aero cover, ~4% with aero cover) assuming the tires are the same.
That being said, assuming OEM tires, this link will answer your question: Teslike.com
In short, OEM 18's with Aero Covers can travel ~7% further than OEM 19's.
Yea I've been surprised how well the 19" have held up. With all this talk of how RWD's REALLY need to be rotated, I've been vigilant about checking the treads but at 11k miles they are all at 7/32 still.19s look so much better, glad to hear they last longer as well. My 19s are still doing great at 18k miles. And I do launch from most stoplights when possible.
efficiency is impacted by weather to a much greater degree than wheels. But, I would believe 5% sounds reasonable
This. The visual different between the 19's and 18's is worth the range loss.19s look so much better, glad to hear they last longer as well. My 19s are still doing great at 18k miles. And I do launch from most stoplights when possible.

Keep the 19" Sport Wheel, It's a $1,500 option, they look so much nicer than the 18" wheel with or without the plastic cover.I'm considering a used M3 and it has the 19" sport wheels.

I’ve gotten used to them. For me range is king. I had 19s on my last 3.The ride was awful. Really rough. The 18s with aero wheels are fine. The ride is orders of magnitude better than the the 19s. My 2 cents.This. The visual different between the 19's and 18's is worth the range loss.
The 18's are gross IMO.
100%I have the 19s. Honestly, it's worth it.
Only concern of mine is that it would increase battery wear & tear for the same amount of driving... but for range anxiety, I'll be keeping my MXM4s.Keep the 19" Sport Wheel, It's a $1,500 option, they look so much nicer than the 18" wheel with or without the plastic cover.
About range, electricity is very cheap, even if it was 5% loss, on a 200 miles, a 10 extra miles would be less than 1 kWh or $0.10.
