Someone mentioned using tires with visible cracks. I wouldn't. That is a sign of "dry rot" and the tires are definitely weakened.
BTW, the age of the tire and exposure to direct sunlight are only two factors. Tires deteriorate due to lack of use. I know that sounds crazy but I had an unused spare tire that cracked after about 4 years. The tire had been stored up under the bed of my pickup. A tire expert explained the issue. Tires have compounds to protect against UV light and oxidation. These compounds are weathered away but are replaced from within the rubber when the tire becomes hot and flexes.
Yup. Although I think we use our trailer often at least once or twice a month. Going today to get new tires spare included.
