Hi all,
Apologies for not being able to respond earlier, it was a busy day yesterday driving back from SLC. So the bad news is the service center wasn’t able to get me in as a walk in appointment and lift the vehicle to test the 19” OEM wheel. However, I was able to lift the car at home and test it for myself and it looks like the 19” OEM wheel will fit just fine.*
I have attached some pictures for others to review, but it appears to sit flush against the hub and there wasn’t any issue with the brake caliper; I even went against my better judgement and manually rotated the wheel slightly to make sure it wouldn’t rub against the caliper/control arm. I remember reading in the manual the car/wheels shouldn’t roll without power while parked, but I figured to be thorough, and since it was a minimal amount of rotation, that the risk of damage was minimal (at most). As a note, I tested the 19” wheel on the front hub and the nuts were not torqued, especially down to spec, so if you notice a tiny gap in the picture, that is most likely why. Also, if the rear caliper is significantly different in size than the front caliper then maybe there will be a rubbing issue, but they look about the same to me.
One last thing, sorry for the awful angle of the wheel when fully mounted, the lighting was not being kind and it was the best I could do in the limited time I had. Also, in my excitement that the 19” fit, I completely forgot to measure the distance between caliper and wheel, or have something as a reference for ease of review.
*Although my 19” OEM wheel appears to fit to my novice eyes, someone with more experience on these forums may notice something I did not. Additionally, Tesla may be selling old 19” wheels (I recall seeing pictures of the old wheels without a 3mm lip accommodation) in their winter tire package; if you buy via Tesla or 3rd party, make sure your wheels have the lip accommodation.
