I plan on ordering the Performance version (P# 1117) soon and wondering what others that live in snow country plan to do for winter tires. The 21" performance tires just don't seem at all practical for those of us living in snow country, so as of now I'll probably buy an extra set of 19" wheels/tires for winter driving. Any other thoughts/ideas about this? Anyone know of 3rd party wheels that fit the S yet? Has anyone gotten a quote from Tesla for and extra set of 19" wheels/tires? I'm retired and don't do a lot of winter snow driving, but cannot handle the idea of not being able to use my S all winter. Anyone interested in selling their 19" wheels/tires?
