Good looking truck! I have a 54 6100 and it came with 8.25 X 20's on it. However when I turn sharply going up an incline the tire rubs on the frame. My old tire man told me that quite often the old trucks used 7.50 X 20's on the front. I put on the 7.5o's and no more problems. I had trouble finding someone to change the tires on split rims so I bought the tools and change them myself. Jim
