I was thinking about getting the Kumho Ecsta 712 (205/50/15), but was concerned how they handle in the rain and snow. I live in Southern California where, its mostly dry weather. But I do like to go up to mountains during the winter time to do some boarding. So my question is, would I be ok taking these tires through the little snow I go through? Would snow chains compensate for the lack of snow traction? Any opinions? Thanks.
