Any tires that I had gotten would last for 5 years. Thus the dollar cost per tread life of the Michelins including the lower mileage is much higher. Although they advertise otherwise, this is entire due to the bad design of their tires. Check the most helpful negative review at Consumer Reports, and other reviews, which got exactly the same result. The average rating was only 3.1/5.

Not a low rolling resistance tire
I purchased them because tires are advertised by Michelin as Low Rolling Resistance. I was aware there is no industry standard on LRR, any one can claim any tire to be LRR, but I trusted Michelin on this and am disappointed. Four new Defender XT tires were installed on well maintained 2011 Prius II, real fuel mpg went from avg of 55 / tank to 47 / tank.

I expected a 2-3 mpg loss that happens when ever a new tire is installed but not 7-8 mpg lost. Miles driven were accurately measured using GPS and gallons were measured at the same gas station on the same pump that is calibrated yearly so the mpg loss is real. Prius display was reporting a solid 10 mpg less.
