I recently had a flat tyre on my Tesla caused by a large nail. Two reputable tyre distributors said that I had to buy a new tyre from aTesla Service centre as Tesla hold the complete stock of unique Michelin, Tesla tyres and furthermore punctures could not be repaired on these tyres because of the foam inserts. I contacted Tesla Technical team who advised me that this information is incorrect. Tesla Tyre punctures CAN be repaired (subject to where the damage has occurred and ALL Michelin tyres can be fitted as long as the tyre size matches.
