Tires, that is a big ticket maintenance item on EV's. Due to all the torque and weight you go through them much faster than normal.
I noticed the nice Michelins on a friend's Tesla this week. Most people I know that drive this class of car spend for good tires as they understand how important tires are. I have one friend who drives M3 BMWs and he goes through tires in 20K miles. I would think that Tesla drivers are similar.
