All motot tire just south of Seattle has them in stock, mounting for free with wheel off bike. Also, South Sound BMW has Heidenau in stock, just off I-5 in Fife, WA (South of Seattle 25 miles). TouraTech has proper size tires in stock, but usually TKC80.
I am in seattle and have a m/c lift if you need some help taking a wheel off bike.
