I totally realize this is a VERY subjective question but I'm wondering how long wiper blades should last in Colorado. We have fairly hot summers and can have very cold winters (albeit not for long stretches). The climate is very dry.
I've read What wears out windshield wipers? and realize that running blades on dry windshields is less than ideal as well as dry climates will dry out rubber faster.
If my current wear and tear is "normal," how often should I be replacing them? Thanks.
