I realize this is probably a loaded question with no clear-cut "line in the sand" answer, but I'd still like to see what people say. I live 3 hours from Tahoe area, so in the winter it is nice to have true ice/snow tires for going to the ski resorts on the weekends. BUT... my Mon-Fri drives around home are done at sea level, on completely dry (or rain wet) pavement, usually in the 45-65F range.
I know why it's not a good idea to drive winter tires year round, but I don't see any published specs from tire mfr's regarding what max temp they suggest their tire be used in. I'm faced with the options of:
a) leaving tires on all winter which at best will cause faster wear on them, and at worst will be a safety concern if I give up traction on wet "warm" pavement
b) swap tires every weekend, which is obviously a PITA, though I know at least one person living nearby who does this
I'm aware that performance winters may have been a better solution for my situation compared to ice/snow tires, but I do not want to even give up a tiny fraction of ice performance, after a scary incident I had on ice last year.
