Sounds like you would like to upgrade your tire and wheels on your trailer. You may substitute a 14 inch tire and wheel as long as you have both the wheel well height and width clearance for it, the capacity of your trailer, and has the 5 on 4-1/2 same bolt pattern.
If you are trying to substitute just the tires, the Kenda # AM1ST77 will fit rims that measure 13 x 4-1/2 inches, 13 x 5 inches, and 13 x 5-1/2 inches. Increasing to the 14 inch 205/75-14 tire like # TR20514 will fit a 14 x 5 inch, 14 x 5-1/2 inch, 14 x 6 inch, and 14 x 6-1/2 inch wheels. It is important to have the same type of tire on the other end of the axle. This will prevent any uneven wear or reduced performance.
A 14 inch tire and wheel combination with the 5 on 4-1/2 inch bolt pattern is the Kenda Load Range D # AM32161. This tire and wheels outer diameter is going to be 26.3 inches compared to your current 24.4 inches with your 185/80-13. This tire and wheel combo will have a width of 8.1 inches.
If you prefer to have a 14 inch load range c tire and wheel combination I would recommend the Taskmaster # TA82MR. This will have an outer diameter of 26.14 inches and a width of 8.5 inches. If your trailer can accommodate these widths, then they will be a great fit for your trailer. It is typically recommended to have at least an inch of width clearance and 4-1/2 inches of height clearance on your trailer for the tires to fit properly.

Hi Jackie, I have 2013 X17Z Jayco Feather camping trailer with 185/80R13 tires on it. My question if I can upgrade my wheels to 14" with 205/75R14 tires?
