Maybe you're looking for a smoother ride. Came off of my Model S @ ~20K mi. when I switched to winter tires. Selling b/c I plan to ride the winter tires until the 21" Arachnids arrive. Last measurements I have from a Service Center visit a few mos. back put the tread at 6/32 on all tires. Pictures are from right before taking the wheels off. Moderate amount of curb rash included at no extra charge. Wheels and tires, no TPMS or caps. In 4 wheel covers (included). Wheels have only ever been handled by the Service Center. Selling all 4 together as a set (no single/spare tire sales). $750 OBO Pick up in Palo Alto.
