I had the suspension aligned because of the TSB (i had a really bad case). I have since bought aftermarket tires/rims and had them aligned again. 5,500 miles later, they are starting to feather again. Short of buying new tires every 10k miles, what can i do?

I would like to hear what settings others are running with similiar setups.

I have 19/245 tires in the front and 19/275 in the back.
