This is a set of (4) brand new Tesla Silver Arachnid Rims for the Model S (not Model X). Not only do they look gorgeous, but they are forged from aluminum and provide about 34lbs of weight reduction over the standard 19" rims. $3,000. Because they're aluminum they lower the total weight of your car and add performance (no tire spin!). The front wheels are 51.8 lbs, while the rear wheels are 53.9 lbs. These are not for sale to the public and are only available from Tesla through their Referral Program. These 4 wheels are fully mounted, balanced, and have the Tire Pressure Monitors installed by my local Tesla Service Center. The wheels have never been mounted and the tires are brand new and never used. Tires are Michelin Pilot Super Sport as shown with (2) 265/35's for the rear and (2) 245/35's for the front. The sale includes: -(4) 21" staggered Silver Arachnid Rims -(4) Michelin Pilot SuperSport (PSS) Acoustic Tires -(4) Generation 2 Tire Pressure Sensors -(4) Tesla logo Center caps Local pickup (cash only) in Los Angeles or shipping at cost to the continental USA via Ground.
