3 Signs Your Trailer Needs to be Repaired
3Signs Your Trailer Needs to be Repaired
Owning a trailer comes with plenty of benefits, whether you use it for work to haul your equipment to and from jobsites or for renting out to your customers. While trailers are great when you need them, they also require regular maintenance and occasional repairs. Without the proper maintenance, you may end up dealing with a costly trailer repair.
KNOW WHEN TO GET YOUR TRAILER SERVICED
A trailer in need of repair can be dangerous for you and those on the road with you. It’s a good idea to know the signs that your trailer needs repair before it’s too late. Let’s take a look at some of the indicators for when your trailer needs to be repaired and some of the most common repairs you could end up dealing with.
Hard to Stop
When it becomes difficult to stop your trailer, it’s time to check your braking system and axles for repair needs. If you suspect the brakes aren’t working or would just like to check them for some preventative maintenance, it’s a relatively easy task. First, lift the trailer up on jack stands. Then, whether they're electric or hydraulic brakes, pull the breakaway and try to spin the wheels. The wheels should be locked up. If the wheels can turn, then further diagnosis would be necessary.

a braking system, but any issues you notice stopping the trailer need to be taken seriously. If you are still struggling to get your trailer to stop, it could also be a sign of a bent axle or another needed repair. Depending on how the trailer is acting, you may need to take off one of the tires to further investigate and discover the issue.

Faulty Lighting
Just about every trailer comes equipped with lights and wiring, and sometimes it needs to be repaired. If the lights are flickering or not working, this can be a significant safety issue. You may be dealing with something as simple as a blown fuse, a loose connection or something as severe as faulty wiring or electrical shorts.
Tire Failure
Tire maintenance is undoubtedly the most critical safety component on a vehicle. Where the rubber meets the road affects traction, handling, steering, stability and braking. Because of this, a sudden tire failure can have serious consequences, especially if it occurs at highway speeds.
Many tires today are capable of going thousands of miles or more — provided they are properly installed, maintained, and inspected regularly. With proper care, tire maintenance and “normal” use, most tires will go the distance without a problem. But sometimes tires fail.
When the trailer starts to pull your vehicle to one side or another, you might have a tire issue. Before each tow, you should check your trailer’s tire pressure and inspect it for wear. During the inspection, you might notice a crack or bulge in one of the tires. If this is the case, it’s time to get your trailer tires checked out and changed before you end up stranded on the side of the road.
Also, trailer tires may be worn out even though they have plenty of treads left. This is because trailer tires have to carry a lot of weight all the time, even when not in use. It's actually better for the tire to be rolling down the road than to be idle because during use, the tire releases lubricants that are beneficial to tire life. So, using the trailer tires often also helps prevent flat spots from developing.
But to do that requires proper maintenance. For starters, it is recommended to carry a tire pressure gauge in your tow vehicle. Secondly, pay attention to these key terms:
Underinflation: Check your tire’s sidewall for recommended PSI (Max

6 Common Trailer Tire Questions
Felling Trailers’ parts and service team field a lot of questions on parts and trailer repairs each day, with the most popular being about trailer tires. Here are the five most common trailer tire questions and the answers from Fellings’ Trailer Tires Parts & Service experts.
How long do trailer tires last?
Trailer tires can last three to four years or 10,000 to 12,000 miles. The tire life may vary depending on the tire’s quality, the type of roads and terrain it travels on, and the load weight that is being carried.
Can you put regular car tires on a trailer? Why?
No, regular car tires cannot be put in a trailer. This can be dangerous. Tire tread on car tires is different than the tread designed for trailers, which can cause irregular wear on the tire and will blow. Load ratings are also carefully chosen for car or truck tires and completely differ from trailer tires.
What is a “load range” on a trailer tire?
The load range is the load capacity of the trailer tire. A tire’s load range is located on the sidewall of the tire. The load range is rated with a single letter, such as B, C, D, etc. If you have two tires of the same size, but one with a load range of B and D, the D range tire will have a higher weight capacity. Keep in mind that going to a higher capacity tire does not increase the capacity of the trailer.
What is the difference between a passenger tire (P) vs. a trailer tire (ST)?
ST stands for “special trailer tire.” P or LT stands for “passenger” or “light truck” tire. Because of an ST tire’s heavier design, it is designated to carry more load than a P or LT tire. Tread patterns between the two are also specific to their applications. STs have an equal volume of air space, and LT tires are sometimes used on larger trailers due to their stiff sidewalls. As a rule of thumb though, you want to stick with ST trailer tires for your trailer. That’s what they are made for.

Do you need to balance your trailer tires?
No, balancing your trailer tires is not necessary. Trailer tires are meant to support a load! You are more likely to feel an imbalance in your vehicle than a trailer. Trailer tires are designed to support the load that is carrying, not providing a smooth ride.
How do you prevent dry rot on trailer tires?
Dry rot happens when the tires sit in the sun over a long period of time. Covering your tires should prevent major dry rot issues. UV exposure and oxygen are the two major degradation factors for tires.
Permissible Inflation Pressure). If tire pressure is lower than recommended PSI, take note of the difference between measured pressure and correct pressure, then add the missing pounds of air pressure to each tire that is underinflated.
Overloaded: Check tire placard, know your capacities, and on the tire face is listed the Load Range as C, D, E, G, etc. The Load Range tells you what the weight capacity of your tire(s) is. Surpassing this limit can result in failure.
Potholes & Other Hazards:
Hazards on the road can impact the internal structure of the tire and be the cause of a blowout in months to follow.
Weather Checking: If a trailer sits stationary and is exposed to the environment for extended periods of time like weeks, months, etc., the tire’s surface can start to crack. This typically occurs on the sidewalls or at the base of the tread grooves causing weather checking or ozone cracking. If this is observed, then it's time to start looking into replacing the tires.
Lack of Maintenance: i.e. all of the above
The most common trailer repair you will encounter will have to do with your tires, but beyond that, there are other common wear parts that will need to be repaired or replaced, such as: • Hub replacement • Bent axles • Repacking bearing • Wiring/lighting repair
Anytime your trailer isn’t towing normal, you want to diagnose the problem. Sometimes, it’s as simple as inspecting the trailer and finding the issue. But you should always complete a pre-trip walk around before each use.
