Has anyone tried replacing dual drive tires with super singles?

[Ross]

There are no super singles over 10,000 each as the market would only
be for overweight vehicles. Too small for production.
Fed law allows the maximum single axle weight to be 20,000 lbs.
Some builders have more than that as their GAWR ,and as a safety
factor ,that is great. Legally ,however , you run the risk of fines or
penalties if the load is over 20,000 lbs.

The 365 tire has a maximum load of over 10,000 but would not be
suitable.
