What’s the Right Tire Pressure for My Trailer, and How Do I Prevent a Blowout?

Key Takeaways
- Tire Pressure is Key: The correct tire pressure for your trailer is the maximum PSI listed on the tire’s sidewall.
- Prevent Blowouts with Regular Checks: The best way to prevent a blowout is to check your tires for correct pressure and signs of wear before every single trip.
- Don’t Overload: Always make sure the weight of your trailer’s load is below its weight limit (GAWR) to prevent tire stress and potential failure.
The correct tire pressure for your trailer is the maximum PSI (Pounds per Square Inch) listed on the tire’s sidewall or on the trailer’s VIN sticker. You prevent a blowout by maintaining this pressure, avoiding overloading your trailer, and regularly inspecting your tires for cracks or wear. A tire blowout is often caused by underinflation, which causes the tire to flex excessively, build up heat, and fail.
At Lowery’s True Value, we’re here to help you understand what the right pressure is and how to prevent that unexpected “BANG!” from happening.
What’s the Right Tire Pressure for My Trailer?
This is the big question! It’s super important because the right pressure helps your tires last longer, keeps you safe on the road, and even saves you money on gas.
Most people think, “I’ll just pump them up until they look full.” But that’s a big no-no. Your trailer tires need a specific amount of air, and it’s almost always different from your car’s tires.
How do you find the right number?
Look on the side of your trailer tire. You’ll see some numbers and letters printed there. The most important one is the “Max. PSI” (which stands for Pounds per Square Inch). This number tells you the maximum amount of air pressure the tire can handle. For trailers, it’s a good idea to fill them up to this maximum pressure. This helps the tire carry the heavy load of your trailer without getting too hot or getting squished.
If you can’t find the PSI on the tire itself, check the sticker on the side of your trailer. The manufacturer usually puts a sticker with the recommended tire pressure and load information right there.
How Do I Prevent a Blowout?
Preventing a blowout is all about being a little bit prepared. Here are some simple steps that can make a huge difference:
Check Your Tires Before Every Trip. This is the number one thing you can do. Grab a tire pressure gauge (we have lots of them here at Lowery’s True Value!) and check the PSI of each tire. It only takes a few minutes but can save you from a major problem.
Don’t Overload Your Trailer. Just like your backpack can only hold so many books, your trailer has a limit to how much weight it can carry. The sticker on your trailer will also tell you the “GAWR,” or Gross Axle Weight Rating. Don’t go over that number! An overloaded trailer puts a lot of stress on the tires, which is a common cause of blowouts.
Look for Cracks and Wear. Take a quick peek at your tires. Do you see any small cracks on the sidewall? Are the treads worn down? These are signs that your tires are getting old and might need to be replaced.

Frequently Asked Questions
- Can I use my car’s tire pressure gauge?
Yes, you can! A regular car tire pressure gauge will work just fine for checking your trailer’s PSI.
- Should I check the pressure when the tires are hot?
It’s best to check your tires when they are “cold,” meaning they haven’t been driven on for a few hours. Driving heats up the air inside the tire, which can give you a higher reading.
- What happens if my tires have too much pressure?
Over-inflating your tires can make them more likely to pop if they hit a pothole or a bump. It can also make your trailer bounce around more on the road.
- What about under-inflated tires?
This is the most common problem! Under-inflated tires can heat up really fast, which is a major cause of blowouts. They also wear out much quicker.
- How often should I check my trailer tires?
You should check them before every trip, no matter how short. It’s a quick safety check that makes a big difference.
