How to Determine the
Age of RV Tires:
There will be two rows of letters and numbers that run around the sidewall of a tire.
The final four numbers on the inner ring of letter and number combinations refers to the week and the year that the tire was manufactured.
For example, if the final four numbers on the inner ring of a tire read 1819, then the tire was manufactured in the 18th week (the first week of May) in 2019.
