42K miles on the 19" OEM Goodyears and still going. I want to replace them soon, but they could probably last past 50K easily.

I have about 33K on the 19" OEM Goodyears. I think I'll get another 5K out of them. Rotated every 7 to 8K.

Has anyone switched to a smaller wheel, 18" or 17", while keeping the same overall diameter for increased sidewall height/comfort, and more tire options?

Just replaced the OEM Goodyears at 30K. If it was summer, I would have pushed them into the wear bars but it is the cold rainy season here. Bought the Pirelli CINTURATO P7 ALL SEASON PLUS , 700 wear index hoping for better longevity.

Totally good choice on car options in your sig line.
But "Totally depends on..."?? Reading this thread, I see NO discussion of road types, very little on driving types.
I live at 1500' above Napa Valley. Everywhere I go is up or down hill, around 15 mph curves, usually with a vehicle behind. I LOVE having a pickup pushing me down the hill (at 5 - 10 mph over speed limit) and then I keep it at speed around the "hairpin". He gone!
And, yes, they speed going up hill, too, there being a college up top, and a lot of young drivers trying to get to class. Or somewhere. You aren't popular on a single lane road seven miles long if you creep at ten under the limit.
My tires last about 20K. I buy from Tire Rack, my local tire dealer puts them on. But I would definitely imagine that ANY brand, type, model or configuration is going to wear poorly up here. but it's "totally" worth it.
When I drove a RAV4EV (VERY carefully) I would get about 20K on my tires, and my friend who lives in the 25mph suburbs and then would drive down the freeway at less than 55, always got nearer to 60K miles. Some difference!! Exactly same tires.
Primacy MXM4's tires
I contacted Michelin regarding the treadwear guarantee for the Primacy MXM4 tires supplied as original equipment on a Tesla. I was told these tires have a treadwear guarantee of 45,000 miles. If you purchase a new set of the same tires from a Michelin dealer, i.e. Discount Tire, the new tires should be pro-rated per the Michelin guarantee.

Agree with this 100%. Driving style and road conditions play more of a factor in tire wear than most other factors. With that said, it would be useful if the manufacturer told us under which conditions the tires were tested to get the tread rating. I think throwing a number like 40k, 50k or even 75k mlies is highly misleading. How does a consumer knowledgeably buy tires?? I've gone with recommendations from Discount Tires and have always felt like they were pushing me into tires they had excess inventory of and wanted to get rid of rather than tires that were best for my car. They never ask about my driving style or where I drive, just rely on some rating in their system. Frustrating to say the least.
im determined not to make the same mistake with the Tesla but have no idea how.

A treadwear number is part of the UTQG rating on every tire. It's not perfect because the only constraint is that it can't be higher than the numbers arrived in during testing, and some manufacturers are more conservative with their ratings than others. So far I haven't seen any evidence that any tires are getting more (on average) than the 19" Michelin Primacy.
The UTQG test is performed on the first 5000 miles on a track and then extrapolated. This is supposed to result in a conservative value because tires wear slower as tread depth is reduced.
The two most important things you can do to prolong tire life are maintaining the inflation pressures and alignment.
As far as road construction goes, new roads wear tires faster than old roads. Mountainous areas tend to use aggregates that will provide more friction (and faster tire wear) than flatland areas do. Gravel roads wear tires out faster than paved roads.

It is my understanding that the UTQG treadwear rating is most useful within one manufacturer's line of tires and understanding their product offerings. That treadwear rating becomes less useful when comparing a tire from manufacturer A vs manufacturer B. The manufacturers do their own testing and assign the ratings themselves. However they are useful in a general approximation of what to expect. The higher the number the better however, as is typical, there are always trade offs... you oftentimes get some feature at the expense of other features. You get this but give up that.
Recently, here in CT there has been quite a lot of road resurfacing going on with the milling off of old asphalt and laying down new road surfaces. I often run on one of these newly resurfaced roads but when I get on that highway, the initial surface is older. The asphalt has a lot of the "fines" eroded away and as a result that initial stretch of road is quite noisy as the pebble and aggregate make noise.
Then the road transitions to the new surface... there is no erosion yet and the road is blissfully quiet. No tire noise at all.
The surface you ride upon, and its condition has quite a lot to do with perceived road noise. A factor that is important to many Tesla owners I suspect.

That's correct as some manufacturers have more conservative ratings than others.
That is also correct. In addition, certain tires are quieter on certain road surfaces than others. So a tire perceived as quiet in California might not be quiet in Colorado.

Glad I'm not the only one. 23k on the car, but 5k of that was on snow tires. The Primacies are now off again and will replace them over the winter sometime. Lots of hills and turns here and I have a heavy foot at every light (it is why I bought the car), but the tire wear is a little shocking.
I am considering using my referral credits for the new set but appears Amazon (with free Prime shipping) is offering the same tires as a significant discount compared to quoted prices from Tesla. Since the wheel aren't on the car, I can ferry them to be mounted up anywhere (we don't have service center anyway) so I might do that. And try to be more gentle on the next set.

New OEM Goodyear at 18k, 39k and 57k. Tire Rack price for 4 tires, delivered to my local installer, was $505.
No way did that have perfect alignment. This is typical toe-out plus camber. If the alignment machine said it was perfect, then the alignment machine was way out of calibration (an unfortunately common occurrence).
