Interesting test. I wonder how much of a weight difference there is between the pizza wheels vs others? Also, I believe the wheels are “turbine” instead of “turbo”
You're right on the 'turbine' wheel naming. I haven't been able to find the wheel weight differences in any specs I have. Maybe a viewer that has both sets can comment. Thanks for the feedback!
I agree with your conclusion, the 427 and 429 are too similar to make a noticeable difference. I had the same experience on my 2015 REx... 428's for summer and 427's for winter... it was hard to tell if the efficiency improved since the wheels were similar weight, same diameter etc. However, now on my 2019 i3s BEV, it has the big 431's and they are much heavier and not aerodynamic at all. They are the widest tires ever used on an i3. So when I bolt on the skinny 427s for the winter the efficiency improvement is noticeable. Now I haven't tried to scientifically prove it like you (altho it would be fun) so I can't provide solid proof, plus summer vs winter variables here in Canada are constantly changing. However it seems that on roadtrips the 427's help make up for some of the range hit from the cold for sure, not to mention the car accelerates much harder with the 427's since they weigh less, tho the tires scrabble for traction at times compared to the sticky EP500's. Keep up the great work!
I am not a fan of how covered wheels look, and as we all know these cars are designed for lower speed usage. I doubt at these lower speeds you will gain anything, other than having an uglier car, ad you can't monitor your brakes etc. at a glance. Thanks for the experiment, I did wonder about this... My main concern with these is proper tire pressure and where to get new tires from that don't cost the price of a cheap ice car?
Fair enough! I run with higher tire pressure to improve the range, as it is one of the bigger factors. I just picked up a screw in my rear tire, and thankfully it could be patched, else ~$600 for a new rear set!
Yep, but for 95% of the time I rarely use any braking (try to use regen only and get the "5 stars" on the driving efficency screen!), so overheating is less of a concern. Thanks for watching!
Viewers may be interested in this Utube video looking at Tesla range differences with different wheel options. Tesla publish data on this so some reliable test data. ruclips.net/video/NYvKxsYFqO8/видео.html The wheel options do vary in width and profile so there are more variables at play. Hope you find this informative and interesting
Thanks for sharing the link. Wheel diameter is quite a big influence. A few percentage points of efficiency due to wheel configuration doesn't sound like much until you multiply it by millions of cars!

Great experiment! Is there a way you could you measure energy usage directly versus mi/kWh?

I’m happy with the look of my Diamond cut 20” wheels even if they are not so energy efficient. ❤
Those 20" are nice wheels for sure. Maybe not as efficient, but low profile tires are supposedly better for handling. Thanks for watching!

My first thought - brake overheating, rotor warping, brake fluid boiling without any air flow into the wheel, but you knew that.
