I am not sure which style wheels are on said trailer so I would not be able to offer any recommendations without a photo, but I have attached a full list of our selection that match this size below. If the old wheel is still usable then you can just swap out the tire for which I recommend the Provider ST225/75R15 Radial Trailer Tire part # TR225LRE. view full answer...
While there is still an option to add some lift to your trailer, the Lippert Lift Kit you mentioned will not work with boot hangers.
Instead, what you'll need is an over/under conversion kit, which moves your trailer's leaf springs to the top of your axle and lifts your trailer approximately the same amount as your axle's diameter plus the height of the leaf spring pack. The correct kit will depend on the diameter of your axles.
