I picked up a set of MotoMaster Total Terrain AT2s today for my GMC Sierra 3500, but they would also fit all 360s with 16" rims and 1.5" spacers. These are regularly priced at $209.95, but currently on sale for only $130. Since my Bridgestone Dueler Revos were down to the legal limit, it was time for a replacement, and at this price, I couldn't resist! AFAIK, these are only available in Canada.

My price, out the door, mounted, balanced, new stems, enviro fees, and taxes, was still only $814 (CDN), that's only about $600 (US) at current exchange rates.
Oddly enough, almost all the other sizes for our trucks are priced a bit higher, at $150 CDN each, but still a great deal.
