Like all types of insurance, if you have a blowout on a steering tire you will likely wish you had them, if you never have a blowout, they are a waste of money. We use a TPMS and check all tires at every stop. Not as complete protection from road debris as the front bands would be but alerts us to other common tire faults that can cause blowouts.
