...and wheel damage, for sure!

Not to mention that the taller sidewall can prevent tire damage.
I went with the Pirelli Scorpion Verde LRR V rated 235/55-18 to keep the overall diameter as close to the original 19” Gemini wheel/tire combo for speedometer accuracy (.1”difference). After 8k miles on them I am really happy with the road feel, ride and most importantly a 255Wh/mi usage that includes many multi hundred mile road trips. Our latest trip will be Phoenix to Orlando in about a weeks time. I’ll keep track of Wh/mi on this highway trip and update the forum.Sorry to resurrect this thread, but I have some questions. First, those who have made this move over to 18" aero, have you been happy with it? Second, from what I see most of the 18" tires that I'm seeing are "V" speed rated instead of "W", will this cause issues? Lastly, I'm trying to figure out which sizes will clear the knuckle that's next to the tire. I've seen 235/55R18 and 255/55R18. I'm thinking of going with 245/55R18 to get slightly narrower for more efficiency but also some more sidewall. DiscountTire's website suggest 245/50R18 for an optional size, so I'm trying to see what I'm missing if anything as there aren't nearly as many of those. Any help/insight would be appreciated!
before your 18" tire replacement, what's your average Wh/mi?I went with the Pirelli Scorpion Verde LRR V rated 235/55-18 to keep the overall diameter as close to the original 19” Gemini wheel/tire combo for speedometer accuracy (.1”difference).

That’s great news! Thanks for pointing this out.Since this thread has become the de facto best place for info about moving to 18" wheels on the Model Y, I wanted to keep the conversation going, and chip in with some new info:
The 2021 Model 3 has new 18" aero wheels! Sure - the biggest visual difference is the new aero wheel covers: flatter profile, with squarer-holes. However, the 2021 18" forged alloy wheels underneath are new as well - every so slightly different than the 18" alloys on earlier Model 3s. And... they have a different load rating: The new 18" Tesla wheels have a 750kg rating stamped inside them - which is identical to the 20" Induction wheels.
Thus - any concerns over running 18" Tesla Aeros on the Model Y due to the weight rating are largely moot if you use 18" wheels from a 2021 Model 3. Now if we could just get Tesla to offer the 18" aero as an off-the menu option!

On the 19” Gemini I was averaging over 275 wH/mi. Brought it down to 256 with the 18” wheel/tire combobefore your 18" tire replacement, what's your average Wh/mi?
UPDATE: Our cross country PHX-FL, 6000 mile trip is complete on the 18” wheel/tire combo. 2 passengers,cooler in frunk, luggage, spare tire, jack, impact wrench and miscellaneous in the back. 95% interstate driving at speeds between 75-85 mph (TX is 80 posted) , head winds both directions, no regen, our average for the 15k miles the Aeros have been on the car is 278 Wh/mi. The trip average was right around 304 Wh/mi.I went with the Pirelli Scorpion Verde LRR V rated 235/55-18 to keep the overall diameter as close to the original 19” Gemini wheel/tire combo for speedometer accuracy (.1”difference).

Not really. The only meaningful difference is the limit on the front axle, but it’s impossible to overload it anyway. I had already updated the charts with the front axle limit and corrected hitch tongue limit for this thread: Model Y Cargo Loading

So I sold my SRY and got MYP.
Anybody know if these will work? Are these the heavier rated wheels? Will they go over my calipers?

So tape a towel over the caliper and see if it rubs?Throw it on the BACK to see! We know that the M3 18" aero wheels fit the front of the MY performance. The speculation is that they will not fit on the rear due to the larger rear brake calipers. But, despite all the speculation NOBODY HAS TRIED IT, so we don't know for sure!
I suspect that it will be very close weather or not it fits, and that even if they don't fit "as is" they would probably fit with a 15mm spacer to move the spokes further out from the caliper...
Please try it and let us know.

Any chance you can take a pic w/ the covers off? Like the Geminis, the 18" Aeros look quite decent as regular wheels when covers aren't necessary (around town, when not taking highway trips). Wonder what they look like on a Y w/o PhotoshopI put 18” Model 3 aero wheels on my Model Y today. I used Pirelli Scorpion Verde A/S Plus tires in 235/55-18 XL104 size and rating. Overall height is virtually the same as the Geminis. The ride is much smoother and quieter than the 19” Gemini/Continentals they replaced. In the short distance I’ve driven on them today, I did notice a lower Wh/mi as compared to the wider 19”s. That is what I was looking for.
I am going to keep track of the Wh/mi over the several thousand milesView attachment 596389View attachment 596390
Don't know if they will fit but don't get the wheel AND tire package -- the tires will be the wrong diameter. I've attached a photo showing the respective size comparison for Model 3 18" wheels and tires and Model Y 19" wheels and tires. 255 50 R18 would be the same diameter. (Model 3 comes with 235 45 R18)So I sold my SRY and got MYP.
