Tesla Model S Arachnid Wheels Michelin Pilot Tires (Set of 4). Factory new, never used. I am selling a brand new and complete set of four 21" Tesla Arachnid forged flow aluminum wheels, with pre-mounted Michelin tires. Already balanced. With TPMS and valve caps. These forged lightweight set of wheels are wrapped with staggered Michelin Pilot SuperSport T0 tires and have 100% tread remaining. That's right, ZERO miles! Tires are 245/35/21 front and 265/35/21 rear. Front wheels are 8.5" x 21" and rears are 9.0" x 21".
