I saw you post from 2015 about "scalloped" tag axle tire wear. I have a 2016 DS on a K2 Spartan. The K2 has the steerable tag. I am having this scalloping issue on the Passenger side tag tire. Seeing scalloped or shaved off portions on the outermost tread. Wondering if you ever came up with any answers? Very strange situation. Thanks for any input you might have. Curtis
