OK guys here goes. I have a set of stock tyres on my 2013 D22, Bridgestone Dueller 693 A/T that have only done 10K. They're in great nick and I'm not overly keen to have to trade them as I won't get any $$$ back. Problem is, I'm planning a Simmo Desert trip, going to Mildura, Flinders Ranges, Oodnadatta, Mt Dare, Simmo, Birdsville, Innaminka, Bourke, Dubbo and back home. My dilemma is, I don't think the Duellers will cope, even though they've only done 10K. I'm on a tight budget and have been thinking to replace them with BFG's or Maxxis A/T's or something like it. I'm kinda thinking at the moment perhaps I should hold on to my stocks and get a set of muddies instead just for the trip. I can get Maxxis MT Bighorns for $250 each which is $100 cheaper than the BFG's. Added benefit is that I keep my stock, so when I get back I can swap over again and run them out for another year or so. Might get some steelies and throw the muddies on so I can swap at will. Biggest question, it's a 5000km trip with 600km of sand but also rough rocky terrain on the way in and out. That's why I'm thinking the muddies, although they're not ideal in sand I thought they'd cope still. What I'm after is some advice from those that've been there done that and constructive criticism is welcome.
