Hi All - Heading to Big Bear today from San Diego. There is a big storm scheduled. I have a P85+ with 21 inch rims. The snow chains are arriving in a few minutes (K-Summit K45) and I hope they will fit. I'll take pictures and share info because there is no information anywhere on using these with Tesla. I'll even consider loaning them out to any Tesla people in the SD area that needs them if they work. I'm not worried about range but just hope that the chains work. Any advice appreciated. Will charge till Sunday with 120V at the cabin so should be good on that too... Fingers crossed!!
