This is a bit off subject for this site but hoping some 'old timer' can help me out. Have a '68 Dodge W-300 Power Wagon which has 5. 5 x 16 split ring wheels. I'm in the process of mounting new tires, 7. 50-16 Power King's. Broke down the wheels, cleaned them up and painted them, no problem. I installed the tubes and flaps inside the tire them placed the assembly onto the wheel. Now I can't get the tube stem through the hole in the wheel. I can't get the tire spread apart far enough without pulling the tire of the bead on the opposite side. I have mounted many 9. 00 x 16 tires on military split ring wheels. These wheels have a tube stem slot but most split ring wheels have only a hole. Is a special tool needed; is there some trick?? Any ideas or suggestions appreciated. I like my '97 diesel but there's nothing like driving an old truck and I won't be able to until I get my front wheels back on.
