I'm getting rid of these after beefing up just a skosh to 14" rims. Pretty good tread all around. I just swapped them in my driveway and the sun had set. Let me know if you want some photos with more illumination!
I would love to have those but I think shipping them to seattle might kill it though. If you don't get any interest from anyone else, please check what the cost would be to freight them to 98126. Tire rack ships tires to all of their customers so maybe it won't be too crazy.
I always forget about shipping on greyhound. At least for heavy boxes, Fedex seemed to be cheaper than greyhound if you have an account. I'll check into it in a bit if I don't get any interest locally.
