My original question was has anyone had experience with a flat and Tesla road service. What was the outcome, a new tire and what was the cost?
Yes, I have. Tesla roadside will contact one of their local "towing partners" on your behalf, and if that towing partner has a loaner wheel, they will bring it. The loaner wheel is always a 19 inch wheel without TPMS (per what I was told when this happened to me) regardless of what actual tesla tire size you have (18,19,20).
My car has is a Model 3P with the 20s, and I had a discussion with the roadside assistance person about this, asking direct, pointed questions about why they would send a loaner 19 inch wheel for my car with 20 inch tires, and they told me that their engineers had determined that the 19 inch wheel was ok with any of the stock tire sizes tesla sells on the car.
Since there is no transmission, I guess that is why they determined they can do this. Anyway, when they come with the 19inch loaner tire, they also bring a loaner tire agreement you need to sign. The tow truck driver will take your damaged wheel to the nearest service center, or, if you want, you can take your own wheel yourself to deal with it. The loaner 19 does not have TPMS so the car throws errors about not being able to read the TPMS. Tesla roadside sends you this fact in an email before hand as well, regarding the lack of TPMS. Guessing they get a LOT of complaints about the wheel still reporting flat... enough that they have a boilerplate email / text they send about it.
The loaner wheel is marked to show it belongs to tesla (unfortunately I have hit 2 potholes this year that have damaged my 20s so am somewhat familiar with this process). In one case, the loaner wheel had red paint smeared on the various spokes in the shape of clumsy "T"'s. In the other case, the loaner wheel had 2-3 tesla red stickers on the spokes.
Tesla has had an issue with people stealing the loaner wheels (as in, getting a loaner wheel and never dealing with their own, original wheel) even though they sign an agreement saying they will do so. Anyway, you have 72 hours to deal with your wheel. If you had the tow driver take it to the SC, then you make an appointment with the SC for them to sell you a tire / rim (or rim and tire) at whatever the rate is for that.
If you took your own wheel, you can go wherever you want to repair, replace it, and then take the loaner back to tesla SC.
In my case, once both rims were damaged and I wanted OEM replacement rims, and tesla charges, I believe 715 a rim for the OEM 20s. The OEM 20 inch tires are PS4S's and those are an expensive tire, I think they charge low 300s for those not including mounting / balancing / new TPMS.
Tesla roadside is pretty communicative during the " I am stuck" process, with updates on the tow drivers progress etc. My tow driver got stuck in traffic so I was stuck for 1.5 hours the second time waiting for him. With that being said, They told me where he was at least 2 different times, and that he was stuck in traffic, so I felt communicated to.
Also, all things considered, there are WAY worse ways to be stuck in a car than in your tesla. I was sitting there in my climate controlled car, took a conference call meeting (possible in other cars of course), and when done flipped on netflix and caught up on an episode of a show I am watching (not possible in other cars, at least not on the cars infotainment system).
I even called my wife and told her to watch episode X of Y because I was watching it in my car while I was stuck. Fairly painless process actually, all things considered, especially because you can take your own wheel and get it repaired somewhere you want to, if you want to do that. I didnt want to be bothered (and my wheel was busted on the sidewall anyway so needed replaceing, and I wanted tesla TPMS etc. No worry about whether some tire shop was going to torque it down correctly or whatnot. Thats what I wanted, and I was willing to pay tesla replacment costs to get it. Not mandatory though.
