As the old saying goes, “a chain is only as strong as its weakest link.” When it comes to towing a trailer, the tires are a crucial component that can make or break the overall safety and reliability of the rig. While it may be tempting to let trailer tires ride on their tread depth alone, there are several other factors that must be considered to ensure the tires are up to the task.
One important thing to keep in mind is that trailer tires have to carry a lot of weight all the time, even when not in use. This constant weight bearing can cause trailer tires to wear out faster than regular car tires, even if they still have plenty of tread left. In fact, some experts claim that the average life of a trailer tire is only about five years under normal use and maintenance conditions. After three years, it is recommended to replace the trailer tires with new ones, even if the tires still have adequate tread depth.
Another factor that can affect the longevity of trailer tires is their level of use. It is actually better for the tire to be rolling down the road than to be idle. During use, the tire releases lubricants that are beneficial to tire life. Using the trailer tires often also helps prevent flat spots from developing.
Proper tire inflation is also crucial for trailer tire longevity. The main cause of tire failure is improper inflation. Check the cold tire inflation pressures at least once a week to ensure proper inflation levels. “Cold” means that the tires are at the same temperature as the surrounding air, such as when the vehicle has been parked overnight. Wheel and tire manufacturers recommend adjusting the air pressure to the trailer manufacturer’s recommended cold inflation pressure, in pounds per square inch (PSI) stated on the vehicle’s Federal Certification Label or Tire Placard when the trailer is loaded to its gross vehicle weight rating (GVWR).
Trailer tires are an essential component of a trailer, providing the necessary traction and support for the weight of the trailer and its contents. However, like any other tire, trailer tires can lose air pressure over time and suffer from heat degradation.
It is important to regularly check the air pressure of your trailer tires, as a drop in pressure can lead to excessive heat build up and potential tire failure. Tires can lose 1 to 3 PSI per month, so checking the pressure at least once a month is recommended. If a tire is under-inflated, even for a short period of time, it could suffer internal damage.
High speed towing in hot conditions can also degrade trailer tires significantly. As heat builds up during driving, the tire’s internal structure starts to break down, compromising its strength. To prevent this, it is recommended to drive at moderate speeds and avoid prolonged high-speed towing.
The average life of a trailer tire is about five years under normal use and maintenance conditions. After three years, it is recommended to consider replacing the trailer tires with new ones, even if the tires have adequate tread depth. Some experts claim that after five years, trailer tires are considered worn out and should be replaced, regardless of their use. However, this is a general statement and it is best to have your tires inspected by a tire supplier to determine if they need to be replaced.
If you are storing your trailer for an extended period, make sure the tires are fully inflated to the maximum rated pressure and store them in a cool, dry place, such as a garage. Using tire covers can also protect the trailer tires from the harsh effects of the sun.
In conclusion, properly maintaining your trailer tires is essential for safe towing and to extend their life. Regularly check the air pressure, avoid high-speed towing in hot conditions, and consider replacing the tires after three to five years of use. Proper storage and tire covers can also help protect your trailer tires.
