I think for now, I will just be buying some replacement tires for the stock wheels. I know right now I have stock LT265/70R17's on it. I want to reuse the factory wheels until I buy a lift and different wheels/tires. I want to go a little bit bigger and I don't have a leveling kit or anything on it, so it is at stock height. Can anyone please tell me the max tire size I can run without fear of rubbing and issues? I am looking for a little wider and fuller look without having to do mods right now. Also, I need some guidance as far as what Brand to buy, that is a good off-road tire and has a good wear life. I have ran Dueler AT Revos on my Trailblazer (2x sets now), but don't know if anyone has ran them on their Duramax and thought they were a decent investment and wore well. Please let me know what your suggestions are. Thanks.:thumb:
