I'm needing some advice. I've searched the forum for the better part of a week and the internet for longer, I believe I'm needing to replace all my tires as they are badly weather checked/cracked. I currently have 8.25-20 on the drivers and 9.00-20 on the steer axle. I have enough 10.00-20 in good shape that I had for my International Harvester project that I'm no longer going to use on it. Would they fit the stock rims? Below is what I've been able to find on the data plates as well as pics of the current setup. I was able to clean off several layers of paint from one of the rims as well. Not sure what the stamping means, but from my research, I believe these not to be the dread "widowmakers", am I correct? Any and all help would be greatly appreciated
