How Much PSI In Trailer Tires | Tire Hubz

Most people don’t know how much air pressure is in their tires, let alone how much psi (pounds per square inch) is in a trailer tire. The average car or truck tire has about 32 PSI of air pressure. That’s enough to keep the vehicle moving on most surfaces, but not enough to provide a comfortable ride or good fuel economy.

A trailer tire, on the other hand, can have as much as 80 PSI of air pressure. That’s because a trailer puts more weight on the tires than a car or truck does. The extra weight means the tires need more air pressure to support it.

If you’ve ever wondered how much psi (pounds per square inch) is in your trailer tires, wonder no more! The answer may surprise you. Most trailers are equipped with four or six tires, and each one contains around 60-80 psi of air pressure.

That means that there is a total of 240-480 psi of air pressure in your trailer tires! This high level of air pressure is necessary to ensure that your trailer remains stable on the road, especially when carrying a heavy load. It’s also important to remember that trailer tires can lose pressure over time, so it’s always a good idea to check them regularly and inflate them as needed.

How Much Psi in Trailer Tires


What PSI Should Trailer Tires Be Inflated To?

Most trailers have four or five tires, so it’s important to know the correct psi for all of them. The average PSI for a trailer tire is between 50 and 60. However, this can vary depending on the type of tire and the weight that it’s carrying.

For example, if you’re carrying a heavy load, you may need to inflate your tires to a higher psi. Always check your owner’s manual or with the manufacturer to be sure you’re inflating your tires to the correct PSI.

Should You Put Max PSI in Trailer Tires?

It is not recommended that you put max psi in trailer tires. Overinflating your tires can lead to a number of problems, including decreased traction, increased wear and tear on the tire treads, and reduced fuel economy. Keep your trailer tires inflated to the manufacturer’s recommended pressure for the best results.

Why Do Trailer Tires Have High PSI?

Trailer tires have high PSI for a variety of reasons. One reason is that trailers are often carrying heavy loads, so the tires need to be inflated to their maximum capacity in order to support the weight.

Another reason is that trailer tires are typically used on rough terrain, so they need to be inflated to a higher psi in order to prevent flats. Finally, high psi trailer tires can help improve fuel economy by reducing rolling resistance.

Small Trailer Tire PSI

Tire pressure is one of the most critical aspects of towing a trailer. Too much pressure and the tires can overheat, too little, and they can become overloaded. The ideal tire pressure for small trailers is between 30 and 35 PSI.

In general, it’s best to err on the side of caution when it comes to tire pressure. Overinflated tires are more likely to blow out, while underinflated tires can lead to uneven wear and premature failure. If you’re not sure what PSI to use, consult your trailer’s owner’s manual or the manufacturer of your tires.

When checking tire pressure, always do so when the tires are cold (meaning they haven’t been driven on for at least three hours). This will give you an accurate reading. Use a digital tire gauge for the most precise measurement possible.

If you notice that your trailer’s tires seem to be losing air frequently, there could be a problem with the valve stems. Check them for cracks or leaks and replace them if necessary. Also, make sure that the caps are tight and secure before hitting the road again.

80 PSI Trailer Tires

If you’re shopping for new trailer tires, you may be wondering what the best tire pressure is. For most 80 psi trailer tires, the recommended pressure is between 60 and 80 PSI. This range varies depending on the load capacity of the tire and the manufacturer’s recommendations.

It’s important to check your trailer tires regularly to make sure they are inflated to the proper pressure. Under-inflated tires can overheat and fail, which could lead to a serious accident. Over-inflated tires can also cause problems, such as a bumpy ride and premature wear.

To get the most accurate reading, use a digital tire gauge rather than an analog one. If you don’t have a digital gauge, you can usually find the recommended pressure range printed on the side of the tire. When inflating your trailer tires, always err on the side of caution and inflate them to the higher end of the range. You can always let out some air if needed, but it’s much harder to add air if you’re already at maximum capacity.

12 Inch Trailer Tire Pressure

If you have a trailer with 12-inch tires, you need to be aware of the proper tire pressure. Overinflated or underinflated tires can lead to problems on the road. The ideal pressure for 12-inch trailer tires is 80 PSI.

However, you may need to adjust this based on the load your trailer is carrying. If your trailer is carrying a heavy load, you may need to increase the pressure to 90 PSI. Conversely, if your trailer is carrying a light load, you may be able to get away with 70 PSI.

It’s important to check your tire pressure regularly. A good rule of thumb is to check it before every trip. This way, you can catch any potential problems early and avoid them becoming bigger issues down the road.

Why It’s Important To Keep Trailer Tires Properly Inflated

10 Ply Trailer Tires Air Pressure

When it comes to 10-ply trailer tires, the air pressure is an important factor to consider. The right amount of air pressure will help to ensure that your tires last longer and provide a smoother ride. Too much or too little air pressure can lead to problems down the road.

The first thing you need to do is find out what the recommended air pressure is for your specific tires. This information can be found on the sidewall of the tire or in the owner’s manual for your vehicle. Once you know this number, you can then adjust accordingly.

If you are carrying a heavy load, it is important to add a few extra pounds of air pressure to account for the extra weight. Likewise, if you are driving in hot weather conditions, you may want to slightly reduce the amount of air pressure in your tires. This will help to prevent them from overheating and potentially failing.

As a general rule of thumb, it is always best to err on the side of caution when it comes to 10-ply trailer tires and air pressure. It is better to have slightly too much air pressure than not enough. This way, you can avoid any potential problems down the road.

Frequently Asked Questions (FAQs)

1. What Is The Ideal Psi For Trailer Tires?

The ideal PSI (Pounds per Square Inch) for trailer tires typically falls between 50 and 65 PSI. However, it’s important to always refer to the tire manufacturer’s guidelines or the tire placard on the trailer, as the recommended PSI can vary based on the tire size, load capacity, and type of trailer.

2. How Often Should I Check The Psi In My Trailer Tires?

It’s recommended to check the PSI in your trailer tires at least once a month, and before any long trips. Tires should be checked when they are cold, as heat can increase tire pressure and give inaccurate readings.

3. What Happens If The Psi In My Trailer Tires Is Too High?

If the PSI in your trailer tires is too high, it can cause the tires to become overinflated. This can lead to a harsher ride, excessive tire wear in the center tread, and increased risk of a tire blowout due to lessened traction and the tire is more susceptible to damage from potholes or debris.

4. What Happens If The Psi In My Trailer Tires Is Too Low?

If the PSI in your trailer tires is too low, it can cause the tires to become underinflated, which increases the tire’s contact with the road and results in higher friction. This can lead to excessive tire wear, decreased fuel efficiency, poor handling, and a higher risk of tire failure.

5. How Do I Find The Manufacturer’s Recommended Psi For My Trailer Tires?

The manufacturer’s recommended PSI for your trailer tires can usually be found in the trailer’s owner’s manual, on a label located on the trailer, or molded into the sidewall of the tires themselves. If you can’t find this information, contact the trailer or tire manufacturer.


If you’re wondering how much psi (pounds per square inch) should be in your trailer tires, you’re not alone. It’s a common question with no easy answer. The amount of psi in your trailer tires depends on a number of factors, including the type and size of the tire, the weight of your trailer, and the terrain you’ll be driving on.

The best way to determine the correct psi for your trailer tires is to consult the owner’s manual or ask a professional at A tire shop. However, as a general rule of thumb, most trailer tires should be inflated to between 50 and 60 psi.
