    Trailer Tires Buying Guide

    To ensure that your towing experience goes to plan, you should ensure the tires of the trailer are in the best condition. If you notice that they are losing pressure, have cracks in the sidewall or irregular tread wear, it is advise to replace them.

    To help you make an informed buying decision, we have produced the comprehensive guide below regarding trailer tires.

    Best Travel Trailer Tires

    Type of Tire

    At the beginning of the tire size metrics, there is a letter that states the tire type. For example, winter tires will have the letters “M+S” whereas trailer tires are labelled with “ST”. The abbreviation “ST” stands for “Special Trailer” and these types of tires are designed specifically for trailers. Unlike standard passenger tires, they are far tougher as they are constructed of a heavier duty material.

    Bias Ply vs Radial

    When browsing through the various tires available for trailers, you will come across bias ply and radial tires. The main difference is the way the plies are constructed within the tire.

    Radial Construction

    Radial tires have plies that run perpendicular across the belt of the tire. They are the best option for trailer tires as they run cooler, less likely to develop flat spots and are tougher due to to the fact they use steel belts. This makes them more suitable for heavy loads.

    Bias Ply Construction

    Unlike plies that run perpendicular, this type of tire has plies that run at 30 degree angles with a cross hatched construction. This provides them with a stronger sidewall but they may not last as long as the radial alternative. However, they are normally much cheaper, which can be very beneficial for those requiring multiple tires.

    Tire Sizing

    On all tires, there will be tire sizes marked upon the sidewall. These include the width, aspect ratio/profile and the diameter.

    The first three digits refer to the width in millimeters, which usually ranges between 145 and 235 mm. The next two digits refers to the aspect ratio or profile of the tire, which is the percentage of the tires width. The last two digits refer to the diameter of the tire in inches.

    Common trailer tire sizes that suit a range of applications include:

    • 235/85r16
    • 225/75r15
    • 205/75r15
    • 215/75r14
    • 205/75r14
    • 185/70r14

    Load Range/Ply Rating

    Just as important as the size of the tire are the load ranges. Depending upon the number of plies and the rating of the ply, will play a big part in the load capacity of the tire. Load ranges for trailer tires vary from B to F, which determines whether they can handle light or heavy loads.

    Speed Rating

    The speed rating of the tire is another rating to check but the majority of drivers will rarely travel at high speeds whilst towing. Most ST trailer tires are rated at 65 MPH/104 KM/H but there are premium tires that exceed these speed limitations.

    The inflation and load conditions may increase or decrease the speed at which the tire is capable of handling. Exceed the speed may result in additional heat, which can cause a blow out such as the below image.

    Uniform Tire Quality Grading

    The UTQG rating of a tire stands for Uniform Tire Quality Grading. It is a rating system that provides additional information such as the tread life, traction and temperature grading of tires. The system is developed by the US Department of Transportation with the ratings engraved onto the sidewall.

    Trailer Tire Pressure

    Inflating the tires to the correct pressure is crucial to ensuring you have the best towing experience. Maintaining the pressure will also extend the life of the tire and ensure maximum safety out on the road.

    Under-inflation causes additional strain of the sidewall that produces excess heat and weakens the structure of the tire. Eventually, this will increase the chance of a blow out, which is very dangerous at high speed.

    Over-inflation is less common and is usually caused by not reading the max PSI rating on the sidewall. Exceeding the maximum pressure reduces the tread contact with the road, causes uneven wear, skipping of the trailer and a bouncier towing experience.

    We strongly recommend that you have a tire inflator that you can use to regularly check the pressures. It is advised to match the pressure of each tire and check them before any long journey.

    Maintenance and Safety

    Maintaining your trailer tires not only ensures that they are safe to use on the road but also improves the longevity of the tires. Inspecting them on a regular basis before departing upon a road trip is essential. Visual checks of the sidewall and tread can uncover multiple defects that could potentially cause a blow out.

    All tires have a lifespan and will need to be replaced eventually. However, exposure to UV rays can reduce the lifespan of the tires quite significantly and cause cracks to appear on the sidewalls. If the trailer cannot be stored under shelter, we strongly recommend that you invest in tire covers for protection.

    Tires that tend to lose pressure after a few weeks or days may have issues with the valve stems. The best way to test whether they are defective is by simply pushing against the stem and listen for any hissing sound. If you do hear the hissing, this indicates that air is leaving the tire and the stems need changing.

    If you intend on leaving heavy loads upon on a trailer that is left to sit around, the tires may develop flat spots. To prevent this from happening, we recommend that you jack up the trailer and place jack stands underneath to keep the tires lifted off the ground.

    Conclusion

    All of our recommendations are suited for a range of trailer loads and available in a variety of sizes. Trailer tires do not last forever and are often left neglected, which can lead to a blow out if they reach high temperatures. Therefore, it is critical that you check them on a regular basis.

    Before purchasing any tires for your trailer, its strongly advised that you ensure the size and load rating is correct. You should also ensure the trailer hubs and other components are is good condition before departing upon any long journeys.
