I sold my Model S and selling my Silver Arachnid Wheels with TMPS for $1200 OBO. Wheels are genuine Tesla wheels ordered, received and installed by local Tesla service center. They are 21" staggered forged rims 8.5" front and 9" rear. I was asked about trying to take pictures for any markings. I looked all over and only markings I can find was the "made in England" label and the Tesla marking on there tire pressure sensors. Wheels are in great shape as pictured. I would prefer local pickup with payment via PayPal, but I am able to ship via Fedex ground throughout the U.S. for $70 a wheel.
PM me if interested.
