How to Pick the Best Trailer Tyre

We may make use of our SUV’s, trucks or cars throughout the week However, trailers are truly the engines of the automobile world. Without them our vehicles, toys, equipment, and all of our daily necessities would not get the place they are required to be. However, how often do we keep track of the rubber beneath our trailers? The most common answer is “very often.” Unfortunately the trailer tyre is one of the least-used vehicle components that travel on the road. Many people don’t know that there are specialized tyres for trailers, even if they aren’t aware of the fact that trailer tyres are not to be replaced with automobile tyres.

What others are reading

When choosing the right tyre for your trailer the tyre’s style size, load range, and the gross vehicle weight ratings (GVWR) should be considered. To aid you find the perfect trailer tyre we’ve not only explained the main distinctions between car and trailer tyres, but also explained how the bias-ply as well as radial tyres differ. Additionally, we’ll explain the correct air pressure and its relationship to capacity for carrying load, proper sizes as well as tread wear tips, and proper maintenance for tyres. Your tow-rig is your joy and pride. Let’s ensure it can tow your trailer as efficiently and safely as is possible.

What exactly is a trailer Tyre?

In the first place, don’t put the tyres of a car onto your vehicle. Car tire is based on ride comfort and the ride, which requires the sidewall being more flexible. It is the opposite for a trailer tyre which has a stiff sidewall. what you need to achieve maximum load capability and stability. Specific tyres for trailers are divided into two categories that are bias and radial. Both are part of”special trailer (or “ST”) tire category. A lot of radial trailer tyres have low resistance to rolling for maximum performance as well as wear-protection. The load ranges of bias or radial ply tires vary from B to F.

Radial Trailer Tyres

The distinctive design that makes up a radial tire includes an inner belt of steel that is positioned at a 90 degree angle from the tread’s center line. Radials have a lower resistance to rolling as compared to their bias-ply equivalents so they are able to disperse heat more efficiently and, as a result, the tread will last longer. The low resistance to rolling makes them more fuel efficient. efficiency. It’s important to note that unlike bias ply tyres these radial trailer tires aren’t likely to have flat spots develop when being used for prolonged durations of time. For trailers with seasonal use, such as campers and travel trailers this is an important benefit of the radials instead of bias.

Bias Ply Tires for Trailers

A different construction style from that of an radial trailer tyre one with a bias ply design has the innermost layer made of cross-hatched nylon as well as steel cords, that are placed in a 30-45-degree angle to the center line of tread. In general they are more durable as opposed to radials, which helps in ensuring stability and reduces trailer sway. When you’re driving the bias ply’s more rigid design tends to allow them to more straight than the radials. They’re also generally less expensive than the radial equivalent.


The search for the best tyres for your trailer will always start by determining the truck’s gross weight capacity (GVWR). GVWR comprises the amount of weight the truck as well as the maximum load it can hold (i.e. it’s “loaded” amount). For instance, A 10,000-pound GVWR travel trailer that weighs 6,300 pounds empty could be filled with 3,700 pounds of cargo prior to its GVWR. In this example of a tandem axle each tyre will need to be equipped with (at at least) an 2,500-pound capacity to carry a load. To determine the load carrying capacity must be minimum to be, just multiply that trailer’s GVWR by the total number of tyres (in our example, 10,000/4 = 2,250). Fortunately, manufacturers of trailers generally include tyres which (when when combined) outstrip that trailer’s maximum GVWR, by an acceptable distance.


The next thing to take a take a look at is the trailer’s Gross Axle Weight Rating (GAWR). The GAWR of every axle in the trailer will always exceed the trailer’s GVWR, however this doesn’t mean that you are able to pull more than your GVWR. Similar to thinking that just because you purchased tyres that have a load carrying capacity that is higher than the trailer was originally equipped with does not mean that you are able to overload your trailer.

Speed Ratings

A second tip on trailer tyres is to be sure to check the speed rating. Although you may find the best price for a high-performance, 14-ply set of tyres speed rating might be lower than you believe. The majority of trailer tyres’ speed ratings range from 65-mph. The tyre with a rating of 65-mph that’s 75-mph along the highway could increase the pressure of its inflation by to as high as 10psi without causing an increases in its load. The numbers that are listed close to the rim’s edge in the picture above, you’ll see the letter “N.” Its speed ratings indicates that the maximum speed rated for the tyre is the speed of 87 in mph.

Capacity for Load Carrying Explained

The load-carrying capacity should be determined in accordance with the trailer’s GVWR and GAWR information. However, instead of being able to match the trailer’s GVWR it’s a good idea to include a small amount of insurance. In the above photo it is clear that each tyre that is on a tandem, single-wheel axle toy hauler can be rated at a maximum amount of 2800 pounds. The trailer that is fully loaded (i.e. its GVWR) weighs in at 9,995 pounds. However the tyres, if they’re inflated to the maximum pressure manage 11,320 pounds theoretically. It is important to note that when using dual wheel models, the carrying capacity of each tyre is lower 2470 pounds. This is a common practice.

Keep the same tire Size

Whatever you opt for bias or radial Ply trailer tyres, it’s ideal to adhere to the recommended size of the tyres by the manufacturer of your trailer’s size. In this way, you should make sure that the load range stays similar (or at a minimum, close to the original load index number of the tyres that is clearly visible along the sides of the tyre). Avoid mixing or matching different kinds of tyres. Different models, brands and types can wear differently and possess a different capacity to carry loads. Be sure to ensure that your spare is the exact size and has the same capacity to carry loads. If you require the spare but it isn’t able to carry the same load as the other ones, you may end in the middle of the road once more.

How to Make the Trailer Tyres Last

Longevity of the tyres on your trailer starts by adjusting the air pressure. Always verify, inflate, or bleed pressure in the event that the tyres have become cold. Also, make sure that you make use of a reliable gauge. Each month, prior to going on a long trip, make sure that the air pressure is exactly where it is meant to be. For trailer tyres it is usually a matter of running them at their highest inflated pressure for the maximum capacity for carrying loads. It is equally important to keep all tyres of an axle at the same pressure. Insufficient inflation can result in lower fuel efficiency, which hinders the maximum potential for braking and reduces the tyre’s performance.

Rotate every 5,000 to 6,000 Miles

Similar to your vehicle, truck and SUVs, rotating the trailer’s tires every 5,000 to 6,000 miles allows the tyres to wear equally as they can. Also, keep an eye on tread wear using the tread depth gauge. The general rule is that trailer tyres must be replaced when the tread depth is 3/32 inches. No matter the condition, tyres need to replace every 6-8 years, and immediately if wear or corrosion, or any other damage is discovered. Maintaining tyres that are relatively new on your trailer could help you avoid more than the inconvenience of having to put in your spare at the end of your journey. It will prevent the type of blow-out that results in flooring, fender as well as body damages to your trailer.

One of Tyres Most feared enemies is the Sun

The life of a trailer tire isn’t easy. Contrary to the treads on your car or truck that might spend the majority of the times in the garage the trailer tyres typically are subject to weather conditions throughout the year. In addition (literally) some trailers have weight constantly on them, like those with enclosed box trailers as well as travel trailers. According to our experience, the most harmful threat that your tyres are subjected to is continual exposure to sun. After prolonged exposure to its UV sunlight, it dries out the oil that is present in the compound of the tyre that causes dry-rotting, and rust. The best method to prolong the life of tyres on trailers is to take them out of direct sunlight either by putting the trailer in shade or (most affordable) covering them from the sun with tyre covers.
