PNW (Puyallup) born and raised. I ran exclusively Dunlop D404 out there. 44K (yes, thousand) miles in 18 months on a Kawasaki Vulcan 800A, and the tires still had viable tread when the bottom end of the engine blew up... multiple 140+ mph runs, twisted the speedometer cable apart, twisted the hub drive apart, twisted the gauge apart...
Honestly, as much as it pains me to say it, if they are still in business, Bent Bike. Carry your wheel in, buy a tire and tube from them, mounting is included in the tire price (or was when I worked there anyway). As is disposal.
Have to admit that the Cheng Shin 140/90-15 installed on my 98 LS650 back in 2000 is still on the bike, and is considered a "good to go" spare for my 2003 daily rider. Thousands of miles on it, and it is a bit dried out, but...
Have a new old stock Dunlop Qualifier (cruiser pattern, not sportbike, totally obsolete) on the 2003 right now. Second one in 2 years, and it is hammered. Looks like a square profile no newer than 1984 tire... even with scraping the floorboards (yes, I run boards on a Savage, hate pegs) regularly. Of course, the tire codes out to either 1994 or 2004...
