How to Check Trailer Tire Pressure for Towable Trailers

Proper tire maintenance is crucial for the safety and longevity of your towable trailer. One of the most important aspects of tire care is ensuring the correct PSI (pounds per square inch). Here’s a step-by-step guide on how to check and maintain your trailer tire pressure.

• Tire Place Card: Check the tire place card, typically found within the entry door or on the side of your camper next to the weight and load ratings.
• Owner's Manual: Your owner's manual will also list the correct tire PSI for your specific trailer.

Once you know the proper PSI for your tires, you can use various tools to check the pressure:

• Manual Gauge: A manual gauge is an inexpensive and straightforward tool available at automotive stores. Simply press it onto the tire valve, and it will display the current PSI.
• Digital Gauge: Digital gauges provide a quick and accurate reading.
• Bluetooth Gauge: These gauges offer the convenience of monitoring tire PSI via a smartphone app.

1. Prepare the Gauge: Whether you're using a manual, digital, or Bluetooth tire pressure gauge, ensure it's ready for use.
2. Check the Pressure: Press the gauge onto the tire valve. The gauge will display the current PSI. Compare this reading with the recommended PSI for your trailer.
3. Adjust as Needed: If the pressure is too low or too high, adjust it accordingly. Most gas stations have air pumps that you can use to inflate your tires to the correct PSI.

While checking your tire pressure, it’s also important to inspect your airbag suspension system if your trailer has one. Like your tires, the air pressure in the suspension system can fluctuate.

• Check Regularly: Check your airbag suspension system as often as you check your tires.
• Maintain Proper Range: Ensure the airbag system pressure stays within 2 to 3 PSI of the recommended range specific to your trailer.

Regular inspections are key to maintaining the proper tire pressure on your trailer. Make it a habit to visually inspect your tires before each trip. Look for signs of wear, such as uneven tread or bulges, which could indicate a problem. Also, check for debris like nails or screws that could puncture the tire.

Proper inflation techniques are essential for the longevity and performance of your trailer tires. Always refer to the manufacturer's recommended tire pressure, usually found in the owner’s manual or on the tire sidewall. Use a reliable tire pressure gauge for accurate measurements. Note that trailer tires often require higher pressure than passenger vehicle tires due to the heavier loads they carry.

Monitor tire pressure during different weather conditions, as it can fluctuate with temperature changes. Cold temperatures cause the air inside the tire to contract, lowering pressure, while hot temperatures cause the air to expand, increasing pressure. Adjust the tire pressure accordingly during extreme weather to ensure optimal performance and safety.

Understanding common tire pressure issues can help you maintain performance and safety while towing. One frequent problem is underinflation. Underinflated tires can overheat, leading to premature wear and potential tire failure. They also reduce fuel efficiency and affect handling and stability. Regularly check and maintain the proper tire pressure as per the manufacturer’s recommendations to avoid these issues.

Overinflation is another concern. Overinflated tires can result in a harsher ride and reduced traction due to a smaller contact patch with the road, increasing the risk of skidding or hydroplaning in wet conditions. Always follow the recommended tire pressure guidelines to avoid the drawbacks of overinflation.

Tire pressure fluctuations can occur due to factors like changes in ambient temperature, long-distance travel, or varying load weights. Regularly monitor and adjust tire pressure to maintain optimal performance and safety. A digital tire pressure gauge can be a helpful tool for easy measurement and adjustment.

At Lippert, we understand the importance of proper tire pressure for trailer performance. Our Tire Linc® tire pressure monitoring system is specifically designed for RVs and trailers. It provides real-time updates on tire status and is suitable for trucks, travel trailers, 5th wheels, boat trailers, towed vehicles, large motorhomes, and utility trailers, ensuring a smooth and safe towing experience.

Regularly checking and maintaining the proper tire pressure is essential for even tire wear, preventing tire failure, and safe travels with your towable trailer. Whether using a manual, digital, or Bluetooth gauge, consistency and accuracy are key. Don’t forget also to monitor your airbag suspension system to ensure a smooth and safe journey. Safe travels!
