Here's a couple a takaways from my (almost) trip to Tuk...The Tuk road was too muddy for passage when I was there. Unless you are specifically planning DS roads on the way north, ride on road tires. There is no need for DS tires otherwise. For the actual Tuk road, order some DS tires online Via Canada and have them shipped and waiting for you in Dawson City. I ordered mine via Fortnine.com Bear spray: Yes, have it attached and readily available-not IN something. On the Cassiar Hwy I came upon 8 grizzly bears walking down the road-not all at once. Some were eating road kill, all were looking for food. I was on the C just after the snow melt in early June. I also camped.
