Model 3 has Arrived.
I am wondering if there will be a class action lawsuit from the P3D owners next year, if the EPA range is impossible to achieve with OEM 20" tires.
I'm sure you can hit it....if you drive under 60 MPH.....

How much would changing tires from the OE Michelin all seasons to a set of performance all seasons or summer tires affect the range by on an AWD M3?
Would Tesla be willing to buy back the tires (even at a discount) before delivery if I ordered a new set of tires for them to install?
Range loss depends not just on tire, but on wheels as well, and on driving style changes - if all that extra traction from premium summer tires, one is always tempted to explore its larger traction envelope, with obvious impact on mileage.
Once a tire is mounted, NO ONE will be willing to buy it back (unless it's obviously defective), so that's not something even Tesla is likely to even consider.
Right, that's what I'm trying to figure out. If I upgrade to heavier 19's with PS4S, I will likely be driving more aggressively so the range will take a hit - which in these scenarios I would happily trade the range for. But if I drive the exact same speed and acceleration as with stock aeros will it still be a big impact or only a few percentage points instead?
My Mercedes dealership has always offered to buyback tires if I send them something else to put on pre-delivery so certainly not the case with every dealership.
And this point I'm sure will be controversial and many will disagree, but I have driven Continential contisportcontact 5 ssr summer tires during the winter in 20 degree temperatures and in non-snow conditions they still perform better than all-seasons in both my RWD C63 and AWD C300. Driving in any snow would be risky and dangerous but I personally have not found low temperatures to be of any issue for summer tires, at least mine specifically. Has there been any actual tests showing significantly reduced performance below the level of an all-season during cold temps?

EPA rules allow manufacturers to use a particular option configuration as the test vehicle. The performance is apparently being classified as an option of the normal AWD.
I base this on the fact that the most recent published EPA results (dated October 2018 - see here: https://www.epa.gov/sites/productio...vehicle-test-results-report-2014-present.xlsx) only have records of two tests for the Model 3 - one in 2017 for the RWD and one in 2018 for the AWD. Those results are apparently being applied to all Tesla Model 3 variants (the MR may be too recent to be reflected in these data and will need its own test).
So basically the 20" wheels/tires are irrelevant - it wasn't the configuration used for the EPA numbers, which appears perfectly permissible under current rules.
That made sense before because you could choose to have the 18" wheels on the P3D. But now all came with 20" wheels. It is no longer a configuration that could be chosen by customer. Could they put on 16" super light weighted wheel/tires and do the test and then give you no option of getting them with the car? Just wondering...
You're thinking of the P as a separate model.
I think from the EPA ratings perspective all the AWD variants (including the Performance) are simply versions of the same car. So the options (considering only the power limiter settings and wheel size) are/were:
1. Power limiter, 18" wheels
2. Power limiter, 19" wheels
3. Performance 20" wheels
4. the now defunct Performance 18" wheels
The fact that option 4 was eliminated doesn't matter because option 1 appears to be the reference configuration they used for all AWD variants anyway.
The whole EPA process is flaky to begin with - great as a general guideline but very inexact. YMMV
