I purchased these to replace the much smaller wheels on my 6500 watt generator. The small wheels were ok on hard flat surface but not on dirt around camp. The mounts on the generator were smaller than the new wheel bearing size. It took a little fooling around an 2 new axel bolts but all went together well. These new wheels make the generator more stable and much easier to move. I scored the durability a little low as I am unsure how long the rubber will last. Time will tell.
