When Should You Replace Your Trailer Tires?

There are many factors to consider when it comes to replacing your trailer tires, and some are less obvious than others. Before you head out on the road, it's important to understand the different conditions that can affect your trailer's safety. In this article, we'll cover the key signs that determine when it is time for a tire replacement. 

Low Tread Depth

Low tread is the most common sign that your tires need to be replaced. Once the tire's tread depth reaches 2/32nds of an inch or less, it's time for new tires. Worn tread increases braking distance, reduces traction, and raises your risk of hydroplaning. If you don’t have access to a tread depth gauge, a penny works just as well. Place it between the tread blocks with Abraham Lincoln's head facing down. If the tread doesn't reach the top of his head, it's definitely time to replace your tires.

Tire Age

Age is just as important as tread depth when it comes to a trailer tire's lifespan. Regardless of how much tread remains, most tires have a service life of about 5 years, or whatever the manufacturer recommends. Exceptions are made for tires that have been kept in climate-controlled storage away from direct sunlight.
To check a tire's age, look for the DOT code on the sidewall. The last four digits indicate the week and year of manufacture. For example, '2125' means the tire was made in the 21st week of 2025. If your trailer's tires are older than 5 years, it's worth considering a replacement, especially if you spot dry rot, cracking, or separation in the tread or sidewall.

Tire Defects

Whether caused by age, impacts, or manufacturing issues, tire defects can lead to trouble if they go undetected. Cracking, bulges, and separation are usually easy to spot with a simple visual inspection, but if left unrepaired, they can result in a serious blowout. Before any trip with your trailer, take a few minutes to check your tires for abnormalities - it could save you from an expensive repair bill down the road.
If you notice these issues on a tire less than 5 years old, it's worth contacting the manufacturer about a potential warranty claim.

Tire Damage

Some things on the road are simply out of our control. While minor tire issues can often be repaired, certain damage calls for a replacement. Impact breaks on the tread or sidewall, large cuts or punctures, and bead damage all fall into this category. Even something as small as a nail is unrepairable if it's within an inch of the sidewall. Tire damage shouldn't be ignored, as letting it go unaddressed can put you and others on the road at risk.

Underinflated Tires

Unlike modern cars and trucks, most trailers don't come equipped with tire pressure monitoring systems to alert drivers when pressure gets too low. Without that kind of warning, underinflated tires can easily go unnoticed, and over time, lead to premature tire failure. When a tire runs below its recommended pressure for an extended period of time, excessive heat builds up in the sidewalls, gradually deteriorating the inner lining. Because this damage can be difficult to spot from the outside, it often goes undetected until the tire blows out. Even if a tire looks fine visually, it's best to check your trailer's tire pressure before every journey.
