I just received my new rubber for this season, so...
I have 3 sets of these, with 1/2 to 3/4 rubber left. They are heat cycled out, but otherwise undamaged.
If you are considering a long enduro these would help keep your costs down.
$50 US per tire. Also have a set of 1/2 worn Hoosier Wets, same size, same condition, same price.
Tires are near Mission BC, but would also consider delivery to Seattle/Ridge/Portland as my season permits.
