there's no difference in range due to wheel size.can anyone confirm downsizing from 21 to 19 or 20 can help increasing range on model Y performance?
weight is always an issue.Maybe I’m crazy, but I thought heavier (larger diameter) wheels harmed range. Like, this was EV gospel.
Is there is, is there no range difference due to wheel size (weight)? I think EV collective wisdom is that there is. Bigger wheels = shorter range.weight is always an issue.
Tesla wheels aren't light, and many aftermarket wheels are also not light; a few are lighter but cost more.
Not the Tesla Model Y LR. The 19” and 20” tires are the same width. Not sure about weight differences of the tires, but the 20” rims do weigh more.In general, bigger wheels generally weigh more and are fitted with larger/wider tires which again weigh more. Added weight reduces range.
Yes. Reducing the weight of the wheels and tires reduces the unsprung weight. Narrower tires have a smaller frontal area which also slightly reduces air resistance. Switching from the OE 21" wheels and tires to 19" wheels and tires will improve efficiency by ~10% starting at ~55 MPH. Wheel size/weight efficiency is also tied to your speed so at speeds over 75 MPH the difference in efficiency is even greater.by downsizing i also mean lighter wheels. the 21" uberturbine is almost 40lb each, if i can shave 5lb at each corner, will that improve the range?
Yes. All of the available MY wheels fit the MYP. At one point (way back at the start of MY production), there was even a 'stealth' variant MYP with the 19" Gemini. Same with aftermarket wheels from TSportline - all of their 19" (and even 18" now) work on MYP. We have the TSportline 18" TSS on our MYP - they fit with no issue at all.side question. does 19" Gemini wheel fit Model Y Performance?
Yes but Tesla will not sell you the Gemini winter wheel package if you have a Performance Model Y (Tesla states the 19" Gemini wheel is not compatible with the Performance Model Y. This may due to the speed rating of the winter tires that is the issue.) The 19" Gemini wheel does fit the Performance Model Y. It is an easy swap that will provide a net ~10% improvement in range and efficiency when used with the Gemini wheel covers.side question. does 19" Gemini wheel fit Model Y Performance?

Hard to give an exact answer, as we traded from a 2020 MYLR w/20" Inductions, and swapped out the MYP's 21" Uberturbine wheels with only 2 miles on the car (the distance from the SC to the shop). But... closing in on 8K miles, with average 294 Wh/mile, including a fair mix of highway and local driving, as well as loading it with 3-4 people fairly often. Very comfortable too, compared to the Inductions.you're running 18" on your MYP? have you noticed increase in range?
Yes, I have 19 Geminis on my MYP right now.side question. does 19" Gemini wheel fit Model Y Performance?
Good point. FYI on our MYP's 18" TSportlines, we have the default ones that come with the wheels: Michelin Pilot Sport 4 (245/50-18). This has yielded average 294 wh/mi over about 8,000 miles.When posting wheel changes and efficiency, it's very important that you post the tire model and size. There are a lot of variables that are being ignored.
