I've got a 1 ton engine hoist I've been using to move materials and equipment around, but the wheels on the damn thing are designed for perfectly smooth floors and I've got some pretty rough concrete in spots. I'm considering buying new wheels for the thing and getting some 4" wheels instead of the 2" ones that are on it. Has anyone had any issues with a replacement of this kind that I can't imagine? I'm going to get wheels good up to 1000lbs each, so even if the weight shifts weirdly, I've got enough wheel capacity for the full 1 ton. I can't think 2" of height would be enough to make center of gravity a concern, but I'm open to being told I'm wrong.
