I would say it is, especially if you don't "control" who's driving the vehicle most of the time...road debris is common and not always avoidable. I purchased new tires from Discount Tire for my daughters Disco...she had a flat at work took the tire in and they replaced it. The seller on the insurance for me was it's a national replacement warranty so it's a no brainer for my kid...and you can figure how that goes!
