Travel trailer tires are even more important, and they must be filled to the proper PSI.


But how do you know what PSI to use? We’ll find out, so keep reading!

It will cost you a few hundred dollars to replace the tires when the thread is gone or when they blow out. Tires will last longer if they are inflated to the proper PSI.


As a result, make sure the travel trailer tires are inflated to the proper PSI.

What is the recommended PSI for travel trailer tires?

In order to maintain the tires in excellent shape, they must be inflated to the right pressure. So, what is the proper tire pressure for a travel trailer?


There isn’t a single solution that applies to all travel trailers. It depends on the kind of travel trailer you have and the type of tire you have.

Unless you replaced the original tires with different load capacity, you should adjust the travel trailer tire pressure to what the placard inside your rig or the manual recommends. The maximum cold pressure is shown on the sidewall of tires by the PSI.


The PSI shown on the tire sidewall is the highest pressure that may be set, but you don’t have to use it unless it’s needed.

It’s crucial to have the right PSI for your RV’s load. Too little pressure may induce sidewall bend, which leads to heating and can cause blowouts. Too high tire PSI might cause the travel trailer to lose traction.

The pressure for the tires will be provided based on the maximum weight bearing capability of each travel trailer. The pressure that has to be set for the tires is usually listed on a label someplace within the travel trailer.


Aside from the label within the trailer, the trailer tire would have typical sidewall ratings. If the tire arrived with the new trailer, the pressure would be the same or nearly the same in both locations, with a tiny variance. When such is the case, everything is simple for you. Just keep the pressure in the tires at a safe level.


Investing in a tire pressure monitoring system, such as this one from EEZ RV, is a smart idea. It’s a multi-purpose system with anti-theft features. It’s a three-year warranty on an advanced alert system for your RV. Every 6 seconds, it continually measures tire pressure and temperature.


Inside the trailer, the label may be absent at times. That information may be obtained by contacting the dealer, or it may be found in the owner’s handbook.


So, how does the average psi look?

Tire pressure on most travel trailers is typically between 40 and 65 psi. Remember, this is what the average numbers look like, not what you have to set. That is to say, most travel trailer tires will be filled to this PSI range.

This range is determined by the weight of the trailers, which typically vary from 1500 to 15,000 pounds, therefore the psi range.



The preceding item is really important.

Set tire pressure for your trailer tires without comparing them to the tires on your neighbor’s travel trailer. Two trailers will always be different, with differing GAWR (gross axle weight rating) and GVWR (gross vehicle weight rating) (gross vehicle weight rating).

That’s all there is to it. The only way to figure out what pressure to use is to consult your manufacturer’s recommendations. If you can’t discover those ratings, have your RV weighed and get professional assistance on how to properly inflate the tires.


Choosing the Correct PSI

So, because your trailer is old, it’s time to change the tires on it. The pressure on the trailer label is different, and the tires you ordered have a different psi.

Now, one thing you should avoid is getting tires with a lower pressure than the one specified on the trailer.

  • The trailer manufacturer specifies the psi for tires that will be needed to support the trailer’s weight, and any lower pressure means the tire will not be capable of carrying that weight. As a result, your tire psi should not be less than that.

What if the psi was higher? This is something that occurs to a lot of individuals. When you purchase a trailer, the tires that come with it are usually just good enough to support the weight of the trailer. When you purchase a new tire later, it may be rated at a higher pressure.

So, what are your options in such situation? Do you go with the pressure shown on the tires or the psi listed in the RV manual?

The psi required to transport the travel trailer’s maximum weight is specified in the RV handbook or label, but the tires have a maximum load rating of psi.


As a result, it’s best to stick to the pressure recommended on the tire. This does not, however, imply that the trailer’s weight carrying capability will be increased. However, due to the greater pressure of the tires, the trailer may not ride as well as it should.

It’s also OK to drop the pressure to the level specified in the trailer. Everything is determined by the pressure and the weight being carried. However, be sure the pressure is not less than what the RV manual or label recommends. Lower pressure will cause the tires to overheat and blow out.

Setting a greater pressure than the tires are rated for will also result in traction loss.


Tires on the trailer need to be replaced.

In most cases, a trailer tire will survive for 4-6 years or even more.

When it’s time to change your tires, be sure you choose ones with the same load capacity.


The trailer would also have numerous additional sections or components that would be intended for that weight, therefore having the same capacity is required. This also aids in the avoidance of psi setup confusion.

Proceed with the pressure you have written on the tires and in the trailer instructions. The psi may be increased to about +5 but not more than 10 at times. This should be avoided at all costs. When you don’t have a full load on the trailer, don’t set the pressure lower than what is specified.

Through trailer tire pressure charts or trailer tire size charts, RV specialists or tire experts may also assist you. If you know what kind of tires were originally installed on the trailer, stick with the same brand and grade.

The trailer is overloaded.

This is one element that might cause tire blowouts or shorten the tire’s lifespan over time. Make sure the trailer isn’t overloaded since your trailer tires won’t be able to take the weight.

The tires are rated for the trailer’s maximum weight. If you exceed that weight restriction, the pressure in your tires won’t be able to handle the load.

Overloading the trailer endangers not only you, your vehicle, and the trailer, but also other drivers on the road. A trailer that is overloaded might slip and flip over, as well as collide with other vehicles.

Regularly weighing your travel trailer might assist you in planning. Because few of us weigh our RVs on a regular basis, we often overburden the trailer without realizing it. That, however, is not a good practice.


Not properly inflating the tires

The weight bearing capability of the tires on the trailer will be reduced if the tire pressure is not adjusted to the figure specified on the tires or trailer.

Inflationary Conditions

The trailer tires’ sidewalls are intended to carry the trailer’s top load, thus they must be properly inflated. However, if the pressure is less than the recommended value, the tire sidewalls will overheat and fail.

Excessive ballooning

Similarly, over-inflating the trailer’s tires might lead to failure. This causes the tires in the middle to wear out. However, the final consequence is the same. As a result, it’s critical that you properly inflate the tires.

Another thing to keep in mind is that when the trailer rolls, the tires will heat up, causing the pressure to rise. As a result, the best practice is to check tire pressure while the tires are cold. This exercise is best done first thing in the morning when you haven’t driven yet.

Before embarking on a lengthy journey, it’s usually a good idea to check the tire pressure. Make careful to perform this first thing in the morning, when the tires will be cold and therefore provide accurate pressure readings.

What are the best trailer tires?

Buying a tire for a vehicle vs a trailer is a whole different experience. Trailer tires are developed specifically for trailers, and the letters “ST” are printed on the sidewalls. Special trailers, abbreviated as ST, feature thick sides. As a result, they are capable of handling the vertical load.

Tires for travel trailers are made by a variety of brands, including Goodyear, Michelin, and others. Choosing the appropriate tire for your trailer or fifth wheel is crucial, so think hard before purchasing a new one.

In addition to adequate inflation,

The most crucial part of keeping trailer tires in excellent condition is to maintain tire pressure. Let’s take a look at the other pointers and see whether they’re getting the same treatment. This advice will undoubtedly extend the life of trailer tires.

1. Examine the sides

Check the sidewalls of your tires before you start your camping trip. Before you hit the road, look for cracks or breaks. It is essential that you have properly fitted tires and do not take any chances. An inspection like this should be on your trip to-do list.

On RVs and campers, people often misuse their tires. It should be your top responsibility to replace tires on schedule. Tires are typically replaced every 4-5 years, so keeping track of them is vital. It’s also possible that you won’t be able to tell whether the tire is still excellent or not. Take the trailer to a specialist and get the tires evaluated in such circumstances.

Remember that a blowout in the middle of the road is both hazardous and expensive. A trailer that breaks down in the middle of the road must be hauled to a mechanic. And it may be a time-consuming and expensive task. That is something you do not want to happen to you.

2. Additional weight on the trailer

Maintaining the specified pressure is required to sustain the weight while pulling a trailer. The manufacturer specifies the maximum pressure that the trailer can withstand in psi.

If the weight exceeds the limit, the tires will be unable to handle the load. And anything may happen as a consequence of this. Remember that even a few pounds of excess weight might cause problems. Make sure you weigh the trailer correctly and stay under the weight limitations.

We often carry needless goods while embarking on a lengthy trip. As a result, the weight reaches dangerously high levels. Keeping a comprehensive checklist and removing unnecessary items might assist in determining the weight.

3. Tire storage considerations

There’s a considerable probability that the travel trailer camper will be damaged while it’s in storage. Ensure that the tires are well-protected. Tire coverings may be used for this purpose. Keeping the tires off the ground might also assist relieve pressure.

Leaving them exposed to UV rays and/or moisture can also harm the tires. Also, throughout the winter, it is essential that the whole trailer be carefully kept; otherwise, you may have difficulty pulling it out the next season.

Other towable RVs, such as pop-up campers or tent trailers, as well as motorhomes, such as class C RVs or class A RVs, need similar maintenance. During the winter, RVs need particular storage.

4. Replace as soon as possible

It is critical to change the tire as soon as possible. Because they have a limited lifespan, you should replace them before a blowout occurs. Otherwise, the consequences might be disastrous. Period inspections on sidewalls, as well as inspecting for wear and tear, may greatly assist in making a decision.

This may be taken care of by routine trailer maintenance. Also, be certain that the tires you use have the same grade and capacity. Many times, you’ll get tires that aren’t the same, which might lead to psi misunderstanding.

It is preferable to get tires that the manufacturer advises. Whether you have a Jayco travel trailer, an Airstream travel trailer, or a Winnebago RV, you must take excellent care of it and change the tires on time.
