How Old Is Too Old for RV Tires?
RV tires can age out before they wear out because many rigs accumulate relatively few miles while spending long periods exposed to heat, sunlight and static loading.
Read the DOT date code
The final four digits of the DOT code typically identify the week and year of manufacture. For example, a code ending in 2424 indicates production in the 24th week of 2024. Check each tire because replacement dates can differ.
Age is only one risk factor
Heat, underinflation, overload, curb damage, long storage and UV exposure can shorten tire life. A newer tire with damage or repeated overload can require replacement well before an age-based interval.
Tread depth can be misleading on RVs
Low-mileage RV tires may still show deep tread while rubber and internal structure age. That is why visual inspection and age history matter more for RVs than for many high-mileage passenger vehicles.
Use load-based inflation information
Pressure should follow appropriate vehicle/tire guidance and actual loads rather than a generic number from another owner. Weighing axle or individual-wheel loads can improve inflation and load decisions where supported by the tire maker’s tables.
