So I'm heading down to the BCS title game in glendale,az from the Portland, OR area and am wondering how bad of an idea it is to keep my blizzaks on the car? I'm kind of worried about the weather but i'm even more worried about how much it's going to eat up my tires that I've only had for one year? I know there are quite a few people who live in Arizona on the board so I thought i would get their take on the weather down there driving on Highway 10 as well. Any input/suggestions would be helpful. Thanks.
