That’s great to hear.I have the performance package with the 21" tires. I got a screw in a rear tire right in the middle of the tread. Easy fix I thought. WRONG! Took the car to a local big box tire facility and when they pulled the tire it had the acoustic foam! The manager remarked that he didn't even know Perelli made an acoustic foam tire. He said they cannot patch it because the foam is glued into the tire and it would ruin their tool. So he said I needed to contact Tesla because he could not order that tire. So I called Tesla roadside service and they said the foam tires cannot be fixed and it would cost me $462.50 for a new one. I just about blew a gasket. My front one that I destroyed a year ago was only $325 and it was truly unusable. This situation is I have a simple screw puncture. So I read an obscure thread on here about taking it to a "small shop" and get a plug. So I found a hole in the wall small tire shop that would do plugs. However when I got there the owner said "we can patch that tire! We have done it before on Tesla's. I explained what the other guy told me and what Tesla said about needing a new tire and he laughed. So I watch in delight as they carefully pulled back the acoustic foam, removed the residual glue, put a bonafide patch on and the reset the foam with some of their glue. I looked perfect when done! Total cost... $25. Your results may vary.
If you google how to repair a tire with foam insulation, one of the results is a how to article from GM (of all companies). They show exactly what your tire repair person did - carefully cut and remove the foam, patch the hole, re-apply the foam piece.
