4.) Use your RV- Tires are designed to be used and will age much faster and dry out if not used regularly. If storing your RV for an extended period of time make sure to at least move the vehicle once every couple months at the least. This helps the sidewalls from cracking due to sitting in one place for too long.

If you are unsure and want to know the year of manufacture on your tires check the sidewalls for the DOT number which tells you the week of the year and the last two digits identify the year. The tire industry sets the standard for a maximum of 10 years but many tire companies suggest changing them every six-years.
