Tire pressures for a trailer

The correct tire pressure on your trailer improves road safety and extends the lifespan of your tires, optimizing the vehicle's overall performance. 

In this article, we explain how to determine the correct pressure and what precautions you should take to avoid problems during your trips.

Why is it important to maintain the correct tire pressure on a trailer?

The tire pressure of a trailer directly affects its stability, load capacity, and fuel consumption. Incorrect pressure can have serious consequences, such as:

• Increased tire wear: Insufficient or excessive pressure can cause uneven wear, reducing the tires' lifespan.
• Loss of stability: Incorrectly inflated tires can affect the trailer's maneuverability, increasing the risk of accidents.
• Higher risk of punctures: Low pressure increases heat generated by friction, which can lead to a blowout.

How to determine the correct pressure for your trailers tires?

To find the correct pressure for your trailer tires, follow these steps:

• Consult the trailer manual: The manufacturer indicates the recommended pressure based on the maximum authorized weight (MMA) of the trailer.
• Check the tire specifications: On the side of the tire, you will find information about the maximum allowable pressure. Adjust the pressure according to the weight you are transporting.
• Consider the load: If you're carrying an empty trailer, the pressure may be lower. On the other hand, with a fully loaded trailer, you will need to adjust it to the maximum allowed.

Practical tips for maintaining the tire pressure on your trailer

Ensure that your trailer tires are always in optimal condition with these practical tips to help you maintain the proper pressure and ensure a safe and efficient trip.

• Check the pressure regularly: Use a pressure gauge to check the pressure before each trip, especially if you plan to cover long distances.
• Adjust the pressure according to load conditions: A loaded trailer requires higher pressure than an empty one.
• Check the tires when cold: The pressure should be measured when the tires are cold, as the heat generated during use can alter the readings.
• Avoid overloading the trailer: Excess weight can cause tire deformation and increase the risk of accidents.

What happens if the pressure is incorrect?

Incorrect tire pressure can cause:

• Low pressure: Increased rolling resistance, higher fuel consumption, premature tire wear, and risk of blowouts.
• High pressure: Less tire contact with the ground, reduced stability, and increased wear in the center of the tread.

Maintaining the correct tire pressure on your trailer is crucial for ensuring a safe and efficient trip. Check the manufacturer's recommendations, regularly check the pressure, and adjust it according to load conditions to prolong the tire's lifespan and avoid incidents on the road.
