Hello
Next season I plan to do about 11 weekend trips from San Mateo to Incline Village (Highways 80 - 267) between mid December and mid March.
I will be transporting precious cargo (my 7 & 9 year old children).
I was thinking of getting another set of rims and winter tires and leaving them on for 3 months Dec-March.
Will there be ice on the roads during these weekend trips? If the answer is yes, either stud your tires or get a studless tire like the WS80, Xi3, etc. Icy roads are much more treacherous than snow covered roads. If ice will be a rare occurrence, then the tires you listed will be OK. Another option for snow covered (but not ice covered) roads is an All Weather tire.
