Shortly after driving away from the dealer, the tire pressure sensor system reported faults. After bringing it in to Tesla they said the newer tires and older car were not compatible, but they could easily downgrade the electronics in the wheels or upgrade the electronics on the car. They were both about the same cost, so I just had them update the wheels.</text><parent_chain><item><author>jac_no_k</author><text>This &amp;quot;continuous deployment&amp;quot; for cars must be a logistical nightmare.
