Tire life
I have a fifth wheel with Goodyear G614 G rated tires. They still have very good tread and still look good but they were made in the 19th week of 2014. I read that you can go between 6 to ten years....

If you’ve kept them clean, proper pressure, used the unit fairly frequently they may good for a while longer. If it’s used once or twice every now and then and sitting for long periods of time, get them professionally inspected. The the worst thing you can do to any RV/Tire is to let it just sit.
