Many RV owners look at tread depth to judge when itβs time to replace their tires. But unlike passenger cars, RV tires often age out before they wear out.
Because RVs may sit for long periods and carry heavy loads, sidewall condition and manufacturing date can matter as much as tread. Thatβs why checking the DOT date code on each tire is important-it tells you when the tire was produced.
Tire manufacturers generally recommend regular inspections after several years of service and replacement within a specific time frame, even if tread appears good. Sun exposure, storage conditions, inflation practices, and weight all influence how long a tire lasts.
Experienced RVers make it a habit to:
β’ Check tire date codes, including the spare
β’ Inspect sidewalls for cracking or bulging
β’ Maintain proper inflation based on load
β’ Protect tires from prolonged UV exposure when stored
Replacing tires based on age as well as condition may feel premature-but it can reduce the risk of roadside failures and costly damage.
