How to Properly Inflate and Check Your Trailer Tires

Proper tire care is important for keeping your trailer safe and running well. Whether you’re carrying heavy loads or going on a long trip, it’s essential to keep your trailer tires properly inflated and check them regularly. This helps prevent blowouts, improves fuel efficiency, and makes your tires last longer. In this guide, we’ll explain how to check and inflate your trailer tires to keep them in great shape.

Why is Proper Tire Inflation Important?

Keeping the right air pressure in your trailer tires is important for several reasons:

Prevents Blowouts — Low-pressure tires get too hot and can burst.
Saves Fuel — Properly inflated tires reduce resistance, helping you use less fuel.
Handles Heavy Loads Better — Correct pressure helps tires support your trailer’s weight.
Makes Tires Last Longer — Too much or too little air can wear tires out faster.

How to Check Your Trailer Tire Pressure

Checking your tire pressure should be part of your regular trailer maintenance, especially before a long trip. Follow these steps:

Use a Tire Pressure Gauge — A digital or manual gauge will give you an accurate reading.
Check When Tires Are Cold — Tire pressure rises when tires heat up, so check them before driving or after they’ve been parked for a few hours.
Find the Recommended PSI — The correct pressure (PSI) is listed on the tire’s sidewall or in the trailer’s manual.
Measure the Tire Pressure — Take off the valve cap, press the gauge on the valve stem, and check the reading.
Compare to the Recommended PSI — If it’s too high or too low, adjust the pressure.

How to Inflate Your Trailer Tires Properly

If your tires need air, follow these steps for safe and accurate inflation:

Use an Air Compressor — A portable or gas station compressor works well.
Add Air in Small Amounts — Inflate slowly and check the pressure often to avoid overinflation.
Check the PSI Again — Once the tire reaches the recommended pressure, confirm it with your gauge.
Put the Valve Cap Back On — This keeps dirt and moisture out.

More Trailer Tire Maintenance Tips

Look for Damage — Check for cracks, bulges, or uneven tread wear.
Check Tire Pressure Regularly — At least once a month and before long trips
Rotate Your Tires — If possible, rotate them to ensure even wear.
Replace Old Tires — Even if they look fine, replace them every 3–5 years since rubber breaks down over time.

Final Thoughts

Keeping your trailer tires properly inflated and regularly checked is an easy way to stay safe on the road.
