I recently got a flat on my rear wheel on a refresh MSLR. I have 21” Arachnids which are awesome but have run into a major problem. Tire is a Michelin pilot sport 4s 295/30/21. They are on national backorder and no one locally had them or could even get them. Had to tow to Tesla dealership who is overnighting one of the two left in their nationwide stock to put on. I’ve asked and evidently no one has a “different “ tire to replace either. Not sure what to do to avoid going through this again ever, much less before there’s a increase in national stock. Poor planning on someone’s part.
