How are new tires going to prevent flats? :h
New tires will not prevent all flats. however. New will give a much better chance. And may prevent tread separation.
As mentioned. Tires deteriorate with age, Tires oil themselves while rolling, as the side walls and tread flex. Trailer "most" trailer tire sit for months at a time, so they don't oil, and dry out really quick.

This is an extremely important concept that applies to any of us who have RVs but may not drive them frequently. I almost learned this lesson the hard way. I had a pickup truck with a 4 year old spare tire stored in the provided location under the truck bed. Due to road damage, I had replaced my front tires a few months before. I decided to buy a new tire for the rear and rotate in the spare. Everything seemed good until a few weeks later when I was preparing for an extended trip. I noticed that the former spare tire had serious cracks.
I learned from an expert that tires deteriorate rapidly if they are not used or infrequently used. Sun light is hard on tires but even in the shade or covered, tires will "dry rot" due to exposure to the air and ozone. Tires are built to "oil" themselves with the heat and flexing of use. Without the heat and flexing chemical that are on the surface will wash off and the tire will rot. With use, protectant chemical in the tire will migrate to the surface and maintain protection. With use a tire should last about 7 years. Without frequent use, a tire will deteriorate in half that time.
