Tire Replacement Guidelines
and Sidewall Weathering
Tire Replacement Guidelines
Goodyear does not state a specific replacement age for RV tires because there are many conditions that dictate a
tire's life span. Some factors that influence how long a tire will last are:
- Usage per year - more frequent usage will result in longer life
- Vehicle storage practices (6 months loaded with little or no rotation is not good!)
- Usage in warmer climates can also impact a tire's overall life due to greater extreme ozone exposure
Sidewall Weathering
Weather cracking is a naturally occurring condition that results from exposure to heat and sunlight. Goodyear's warranty
for weather cracking is four years from purchase date (or four years from manufacture date if proof of purchase is not
available).
Weather cracking is common in RV tires from all manufacturers.
- Appears as crazing and or cracking in the flex area of the sidewall
- Probable causes of sidewall weathering
- — Long periods of inactivity or storage
- — Direct exposure to air and sunlight
- — Exposure to high levels of ozone (smog, electrical generators)
- — Excessive washing or dressing using alcohol or petroleum based cleaners
When should the tire be replaced?
- Cracks > 2/32" deep
- Internal components of tire (steel or fabric body plies) are visible
Without evidence of weather cracking, use the following as a gauge:
- Usage per year --More frequent usage will result in longer life
- Vehicle storage practices (6 months loaded with little or no rotation is not good!)
- Casing quality --Absence of repairs, liner wrinkles, weather cracking, sidewall scuffs or cuts
Tread Depth
Tread depth is an indication of whether the tire can safely remain in service. Less than 6/32" tread depth may require
replacement to maintain sufficient traction and handling performance. Consult your local Goodyear RV tire retailer to confirm
that your tires need replacement if you measure less than 6/32" tread depth remaining.
Casing Quality
Satisfactory casing quality is another gauge of a tire's overall condition. Casing quality relates to inner liner wrinkles,
tire repairs or any visual signs of tire abuse (sidewall cuts or scuffs etc).
