I am trading in my P85D for a X and have some gently used winter tires and rims. They are 19" directly from the Lawrence store Jan 2015. On the invoice they are labelled as "winter tire set" - they are Pirelli Sottozero 19" 240 OEM directly from the Lawrence store Jan 2015. They are currently in storage at the Lawrence store. They have been used for 2 winters, approx. 10k of use, and the tread has been noted to be 8/32 by Tesla Service. They were $2700+ tax new (ouch!) Contact me if you are interested with an offer.
