I'm selling a set of the Track Package / Referral Rims and tires for $3000. They're in my garage. Tesla just delivered them today. Never mounted on a car. Still have all the factory stickers, etc.
I believe they are 40MM. It says 20x9.0J +40MM on an inside spoke. They are the rims that come with the track package upgrade (
Model 3 Track Package). They are wrapped in Michelin Pilot Sport 4S 235/35 ZR20 rubber.
