I'll start off by saying, thank you for the picture; you can tell that you're taking the necessary precautions to maximize the life on your tires by not only keeping your 5th wheel shielded from the elements with a car port, but also using tyre guards like the Adco Ultra Tyre Gard RV Wheel Cover # 290-3953 to help specifically shield the tires from UV rays-which are especially hard on tires.

Generally speaking, you should change the tires on a trailer every 5-6 years from the time they're mounted on your trailer (assuming that they were stored in a controlled environment between manufacture and resale). Since you're not driving on them much, I think it's safe to use this number as your baseline, but I recommend checking them periodically, and before and after each trip for cracks along the sidewalls or general deformities that may be indicative of dry rot on the tires- which is going to be your main concern with such limited use. As long as the tires don't appear to be gaining small cracks and scaling, they should be safe to use. However, as soon as they start showing those signs, it's going to be time to change them out for new ones. I can't give you a specific time because of the variables but after 5-6 years of safe storage, it's probably time to start paying close attention and be ready to replace them; it may not be necessary immediately, but there is a good chance it's around the corner.
