Thanks, Kiwakwe and PNWexplorer, for your input on the tire question. I've got quotes on the BFG KO2, General Grabber ATX, and the Hercules Terra Trac AT from a highly recommended local shop that installs and balances for the same price as you'd pay for just the tires, online. Since our dollar is currently worth about 75 cents US, the prices reflect that, so I'm looking at $250 to $300 each for any of them, in the 33" size that I need. All of these have the tri-peak snowflake symbol, which makes them legal for winter use here in BC. Almost all my off pavement driving is mountain logging roads, which are mostly gravel and rock depending on state of repair, but seldom mud, so an AT is what I need.
I've eliminated the cheapest of those, the Hercules, after seeing some negative feedback regarding sidewall failures, but I haven't looked into the Falkens yet, so I guess that's my homework for tonight.
