Those tubeless 10 lug on 7.25" wheels actually came with 8x22.5 or even 7x22.5 tires. These sizes likely aren't available any more, I haven't seen theme except old crispy tires on these wheels.
The available replacement is a 9R22.5 tire, which should be used on 6" wide rim minimum. The old wheels are only 5.25" wide, the 9R22.5 tires do still easily fit and in many cases will work fine, but not advised by the tire manufacturer.
