If your current wheels are 14 inches in diameter, and have a 5 on 4-1/2 inch bolt pattern, the Taskmaster # AX02455545FPS Aluminum Viking Series wheel would work great for you. The wheel is 5-1/2 inches wide, and will accommodate a 205/75-14 or a 215/75-14 tire size.
If you need a replacement tire, I'd recommend the Kenda # AM10235 205/75-14 Radial Tire in load range D. The tire has a 2200 lb per tire/4400 lb per axle capacity which is plenty for the 3500 lb GVWR of your Travel Trailer. view full answer...

For a hitch ball then you'd want the # A-90 and you'd be set. view full answer...
