I have a set of Michelin Defender LTX MS on my 03 Suburban 1500. Not sure of the mileage, I am guessing somewhere around 10k.
I had some cupping (choppy) wear on my inner front tires at my first tire rotation interval around 5k miles.
The wear had a low spot on the front edge of each inner tread block and the opposite side of the tread block was high.
I put new shocks on the front and adjusted torsion bars.
The tires were rotated to the rear, which also has relatively new shocks.
Now at another 5k miles, the outside of those same tires on the rear are cupping. The middle tread wear is good, even and still pretty deep.
Could this type of wear be a tire issue? I can't imagine any suspension related issue on the rear that would cause outside tread wear.
Perhaps my outer tread blocks are cupping because of the bounce created by the choppy inner tread wear?
They are starting to get noisy as well on highway.
