Trailer tires – whenever, whatever, wherever

For best performance, your trailer should be outfitted with Special Trailer (ST) designated tires. These tires are engineered specifically for the demands of towing, including riding under stiff suspension systems that are less sophisticated than automotive suspension systems. ST-sized tires can carry the full weight rating indicated on the sidewalls and run cooler than passenger tires, an important detail when towing.

Many people assume trailer tires are just like car tires when the reality is that trailer tires are not engineered like passenger or light truck tires. They are designed to follow the vehicle towing them, and do not need to steer, transfer power from engine to road, or swerve to avoid obstacles. Their sole purpose is to carry the required loads safely without swaying and impacting the performance of the towing vehicle.

Stiffer sidewalls, heavy duty materials and higher operating pressures are vital for a stable trailer that can be pulled easily.

Proper air pressure is just as important with a trailer tire as it is with a passenger. However, due to the stiffer sidewalls, an under-inflated trailer tire will not sag like a passenger tire will. Because pressure loss isn’t easily spotted, a quality tire gauge should always be on hand, and air pressure should be checked frequently. Don’t forget to check the pressure of the spare tire as well!

A common misconception is that trailer tires do not need to be replaced until the tread shows sign of wear. While this is true for your car, the key indicator of when you should change your trailer tires is time. Recommend that after 4 years of use have your ST Trailer tire inspected by at tire professional at OK Tire.

Your local OK Tire will help you find the right trailer tire for you based on size, type and load range. They will discuss the difference between radial and bias ply tires and help you make an informed decision that will have you confidently towing in no time.
