For a more off road tire you are going to be looking at the Westlake ST235/75R15 Radial Tire w 15" Phoenix Aluminum Wheel # LH52FR. This tire is 28.9" tall with a width of 9.3". Compared to the ST205/75R14 # AM32131 which is 26.3" tall and 8.1" wide. This means you will need to ensure you have 4-3/8" vertical clearance so you have 3" of suspension travel vertically on top of the additional 1-3/8" of increased radius of the tire. You will also need to ensure you have 1-5/8" of sidewall clearance on both sides of your tire. 1" for clearance on the new tires and 5/8" for the increased width of the tire on each side.

Please let me know what you find as I can possibly help you with suspension lift on your trailer depending on what suspension system you have.
