I have a confirmed P85D order for a December delivery. Wanted to get S owner perspectives on running with the mandatory 21 inch rims for both summer and winter. I am in the Toronto area and plan on driving the P85D as a daily driver plus road trips on most of the Eastern Supercharger routes in all seasons (major snow). In reading the postings there seems to be a lot of P85 and P85+ owners that are running on 19's for summer and winter. Should I be worried about being locked into only 21's on the P85D with respect to bent rims/flat tires etc?
