When it comes to towing a trailer, proper tire inflation is crucial for safety and performance. Trailer tires are designed to carry heavy loads and withstand the stresses of towing, but they require the right amount of air to function properly. In this article, we’ll explore the importance of knowing how much air is in your trailer tires and provide guidance on how to check and maintain the correct pressure.
Why Proper Tire Inflation Matters
Proper tire inflation is essential for several reasons. Firstly, it affects the overall safety of your towing experience. Underinflated tires can lead to reduced traction, increased stopping distances, and a higher risk of tire failure, which can result in accidents or damage to your trailer or tow vehicle. Secondly, proper tire inflation improves fuel efficiency and reduces wear on the tires, which can save you money in the long run.
How to Check Your Trailer Tire Pressure
To check your trailer tire pressure, you’ll need a tire pressure gauge and a few minutes of your time. Here’s a step-by-step guide:
1. Make sure your trailer is on level ground and the tires are cold (i.e., not hot from driving).
2. Locate the tire valve stem and remove the valve cap.
3. Press the tire pressure gauge onto the valve stem and take a reading of the current pressure.
4. Compare the reading to the recommended pressure, which can be found on the tire’s sidewall or in your trailer’s owner’s manual.
5. Add air as needed to reach the recommended pressure, then recheck the pressure to ensure it’s accurate.
What Happens If You Don’t Check Your Tire Pressure
Not checking your tire pressure can have serious consequences. Underinflated tires can lead to:
Reduced traction and control
Increased stopping distances (See Also: Do Tires Come With A Warranty)
Tire failure and blowouts
Increased wear on the tires and suspension
Poor fuel efficiency and increased fuel costs
In this article, we’ll delve deeper into the importance of proper tire inflation and provide guidance on how to check and maintain the correct pressure for your trailer tires. Whether you’re a seasoned RVer or just starting out, understanding how much air is in your trailer tires is crucial for a safe and enjoyable towing experience.
How Much Air In Trailer Tires: A Comprehensive Guide
When it comes to trailer tires, maintaining the correct air pressure is crucial for safety, performance, and longevity. Underinflated tires can lead to reduced traction, increased wear, and even tire failure, while overinflated tires can cause uneven wear and reduced braking performance. In this article, we’ll explore the importance of proper air pressure in trailer tires, how to check and maintain it, and provide a comprehensive guide on how much air to put in trailer tires.
The Importance of Proper Air Pressure
Bernoulli’s principle states that the pressure of a fluid (in this case, air) decreases as its velocity increases. When a tire is underinflated, the air inside the tire is moving at a slower pace, which increases the pressure on the tire’s sidewalls. This can cause the tire to flex more, leading to reduced traction and increased wear on the tire’s tread and sidewalls.
On the other hand, overinflated tires can cause the tire’s tread to flex less, which can lead to reduced braking performance and increased risk of tire blowouts. Additionally, overinflated tires can also cause the tire to ride rougher, which can lead to reduced handling and increased driver fatigue.
How to Check and Maintain Air Pressure
Checking and maintaining air pressure in trailer tires is a relatively simple process. Here are the steps to follow:
-
Make sure the trailer is on level ground and the tires are cool.
-
Check the tire’s sidewall for the recommended inflation pressure, which can be found in the tire’s information placard or on the manufacturer’s website.
-
Use a tire pressure gauge to check the current air pressure in the tire. You can find tire pressure gauges at most auto parts stores or online. (See Also: Does Triple A Plug Tires)
-
Compare the current air pressure to the recommended pressure. If the tire is underinflated, add air to bring it up to the recommended pressure. If the tire is overinflated, release air to bring it down to the recommended pressure.
-
Check the tire pressure at least once a month, and before each use, to ensure it remains at the recommended level.
How Much Air to Put in Trailer Tires
The amount of air to put in trailer tires depends on several factors, including the tire’s size, type, and manufacturer’s recommendations. Here are some general guidelines:
| Tire Size | Recommended Inflation Pressure (PSI) |
|---|---|
| ST225/75R15 | 35-40 PSI |
| ST235/80R17 | 40-45 PSI |
| ST245/70R19.5 | 45-50 PSI |
It’s important to note that these are general guidelines and the recommended inflation pressure may vary depending on the specific tire and manufacturer. Always check the tire’s information placard or manufacturer’s website for the recommended inflation pressure.
Additional Tips and Considerations
Here are some additional tips and considerations to keep in mind when it comes to air pressure in trailer tires:
-
Always check the tire pressure when the tire is cold, as driving can cause the tire to heat up and increase the air pressure.
-
Use a tire pressure gauge that is accurate and reliable, as an inaccurate gauge can lead to incorrect air pressure readings.
-
Check the tire pressure regularly, as it can change over time due to temperature fluctuations, tire wear, and other factors.
-
Consider investing in a tire pressure monitoring system (TPMS), which can alert you to changes in tire pressure and help you maintain the correct air pressure.
Conclusion
Maintaining the correct air pressure in trailer tires is crucial for safety, performance, and longevity. By following the guidelines outlined in this article, you can ensure your trailer tires are properly inflated and ready for use. Remember to check the tire pressure regularly, use the correct air pressure for your tire size and type, and consider investing in a TPMS to help you stay on top of tire pressure maintenance.

Here are five FAQs related to “How Much Air In Trailer Tires”:
FAQs: How Much Air In Trailer Tires
What is the recommended air pressure for my trailer tires?
The recommended air pressure for your trailer tires can be found on the tire’s sidewall or in your trailer’s owner’s manual. It’s essential to check the pressure regularly to ensure proper inflation and to avoid tire damage or blowouts. You can also consult with a tire professional or the manufacturer’s website for more information.
Why is proper air pressure important for trailer tires?
Proper air pressure is crucial for trailer tires because it affects the tire’s performance, durability, and safety. Underinflated tires can lead to reduced traction, uneven tire wear, and increased risk of tire failure, while overinflated tires can cause reduced traction and increased risk of tire blowouts. Proper air pressure helps maintain optimal tire performance, extends tire life, and reduces the risk of accidents.
How do I check the air pressure in my trailer tires?
To check the air pressure in your trailer tires, you’ll need a tire pressure gauge. Make sure the tires are cold, meaning the trailer has not been in use for at least three hours. Remove the valve cap and press the gauge onto the valve stem. Take a reading of the pressure and compare it to the recommended pressure. Add air as needed to reach the recommended pressure.
Can I use a tire pressure gauge at a gas station?
Yes, you can use a tire pressure gauge at a gas station, but make sure it’s a gauge that is specifically designed for tire pressure measurement. Some gas station pumps may not have a built-in gauge, so it’s a good idea to check before using it. Additionally, be sure to check the pressure when the tires are cold, as mentioned earlier.
How often should I check the air pressure in my trailer tires?
It’s recommended to check the air pressure in your trailer tires at least once a month, or before each use if you use your trailer frequently. This helps ensure the tires are properly inflated and reduces the risk of tire damage or failure. You should also check the pressure after towing or hauling heavy loads, as this can affect the tire’s air pressure.
