Do you buy Road Hazard Warranty?

Costco is running a coupon for $70 off michelins (you probably know that). I never buy road hazard, and had forgotten what it was. I haven't had a flat in years or a tire repaired. Seems like a low risk. I also never buy insurance like this, since I know that the companies set the prices on these policies high enough so they make a killing: the customers always lose big time on average.
