Whose Running Michelin Defender LTX M/S tires on a 1/2 ton??

Had a set of Defenders on my wife's Malibu. Terrible tires, uneven wear, refused to stay balanced. They were down to the wear bars well short of the 90K mileage rating, but it was more than three years, so no adjustment. No more Michelins for me. I always have bad luck with them.
