My experience is the tires will rot before they wear out. Hard to put enough miles on a camper trailer, i.e. popup.
They will rot just standing there and some say they last longer when driven more. Any tires over 5-6 years are likely unreliable, even premium Michelins, when used or stored on a trailer, unless kept out of the sunlight (which is brutal here in the desert Southwest.)
Depending on where you are, Walmart has a great selection in all price ranges and quality, even online. For years I wouldn't shop there, but since moving to New Mexico, I have found many great items in the local stores, and to my surprise, while the customers often leave something to be desired, the staff tends to be super polite and helpful.
