Many tire shops will not touch split rims now, no matter what the style. What is your wheel bolt pattern? If it is 5/10 on 7.25, tubeless rims are hard to find but out there. Started with first tubeless in late '50's, look on farm trucks. 9" tires will fit on those wheels, are the most readily available size. About 36" OD.

Joined: May 2005 Posts: 8,878 | The larger tires on front of an AD truck may, or will, limit how far you can cut the wheels in a turn. The larger tires rub at back of leaf springs. | | | | | Joined: Nov 2017 Posts: 33 'Bolter | | 'Bolter Joined: Nov 2017 Posts: 33 | That's kinda what I was thinking. I've got a good set of 8.25x20 I can use. | | |
