I walked into a tire store and got the same speach when looking for tires for my 41. Split rims can kill! Well ok. So I started to hunt for some wheels that would fit. I found some ten luggers off a1978 GMC bread van. The only problem was the center hole is bigger than on a 41 11/2 ton, so I use the axels from my old 54 2 ton which had 51/4" center holes and smaller rear drums. The track in the front is 2 1/2 inches wider on each side than a 41 but only a 1/2 inch wider than a 46, so everything fit rather nicely. The wheels were sandblasted and powder coated for $16 each, new radial tires were mounted, they are lighter and easier to mess with and to be honest don't all that different on a dump truck any way. Each to their own solution. I just didn't want to spend $1500 on tires and place them on wheels no one was willing to maintain. But I'm not a purest. Good luck on your solution.
