Run Flat Tires

I have run flat tires on my mini-van (actually it is more like my friend Darcy says .. "Uhm girlfriend, there ain't nothin' mini about that van").

I am run flat tired these says and even more so upon hearing my darling father-in-law express with visible dismay that my tires needed to be replaced. There are lawsuits pending or resolved etc. Now I am going to somehow need to deal with the idea that I need to get my tires replaced on what feels like a new car, which I can get over, but the whole deal whereby I receive possibly free new tires if I sign away my rights to further litigation. I hate all of that stuff. I know it's no big deal but my tread is unevenly wearing these days.
