Buying the Right Tires for Your Trailer


There is a wrong perception that trailer tires  are similar to car tires and this wrong opinion is the reason why many people end up changing tires too soon and waste a lot of money. Trailer tires and wheels are different than average car tires and that is why it is important to buy the right tires for your trailer.


          There is no denying that the most critical piece of equipment for any kind of trailer is tires. Whether it is a cargo trailer, car hauler, utility trailer, or a horse trailer, it is imperative to use the right tire for the job to ensure that your equipment is safe and the ride is fully comfortable. Needless to say, if you are using the right tires, your trailer’s efficiency will increase, it will be more stable and pull better.

Important Requirement to Consider Before Buying Trailer Tires

You have to keep in mind that there are different requirements for the tires on a trailer than the ones for the tires on a tow vehicle. Two of the most integral elements of a passenger car tire is:

-         Comfort: The comfort part is achieved by simply making the sidewalls of the tire soft enough so that they can easily flex under normal driving conditions.

-         Traction: The traction is needed for turning, acceleration, and braking.

Other key components of trailer tires that always need to be considered are inflation pressure and load range. The ST (Special Trailer) tires are specifically engineered for heavier loads and run at higher inflation pressure as compared to passenger car tires.

ST (Special Trailer Tires) vs. Passenger Car (P) Tires

These tires are specifically designed for your trailer’s requirements. In order to prevent your rig from swaying, these tires have stiff sidewalls. Their heavy-duty capacity makes them more suitable for your trailer – these tires have 40% more load capacity as compared to Passenger car (P) tires and 10% more than LT tires.

Passenger car tires achieve comfort by softening the sidewalls of the tires (this also enables the sidewalls to flex). Given the fact that many trailers have a higher center of gravity as compared to a typical tow vehicle, the sidewall flexing can be responsible for an increased trailer sway. This is where ST tires prove to be very useful with their higher inflation pressure and stiffer sidewalls.

In addition, the polyester cords in ST tire are bigger as compared to an “LT” or “P” tire. And ST tire has steel cords that have the greater tensile strength and larger diameter to easily meet the additional load requirements.

All in all, it is fair to say that ST tires provide a better pull and smooth ride to the trailers as compared to other tires.

Trailer Tire Safety Tips

Here are some tips that’ll help in increasing the service life of your trailer tires and wheels:

-         Maintain the right trailer tire pressure

-         Prevent contamination  of internal rubber valve by keeping a cap on the valve stem

-         You need to know about the maximum load for the tires of your trailer. Make sure that you do not overload tires of your trailer (extra weight increases the chances of a flat tire because more weight creates more heat)

-         You need to get the right size of the tires of your trailer

-         Check the tires monthly for any sidewall cracks, air loss, signs of damage, or irregular tread wear patterns

-         Have the tires inspected once in a year

-         Always have a spare tire

-         Regardless of the tread wear, it is best to replace tires every 3-5 years
