Tire Care and Maintenance

Tire care is crucial for the safety and efficiency of your dump trailer. By keeping an eye on a few key aspects, you can ensure your tires are always in good shape, ready to take on the load and the road ahead.

Air Pressure

PSI matching is the first step in tire maintenance. It’s essential to inflate your tires to the pressure recommended in your owner’s manual. Why? Because the right air pressure ensures your tires wear evenly, improves fuel efficiency, and prevents accidents.

Here’s a simple way to remember it: Too little air, and your tires wear out on the sides. Too much air, and they wear out in the middle. Just right, and you get the longest life out of your tires.

Checking the air pressure should be part of your pre-trip routine. It takes only a few minutes but can save you hours and dollars down the road.

Damage Inspection

Next up, inspect your tires for uneven wear and excessive wear. Uneven wear could indicate issues with your trailer’s alignment or suspension – something you’ll want to get checked out. Excessive wear means it’s time for a replacement.

Look for signs of damage, too. Things like cuts, punctures, or bulges on your tires are red flags. These issues can lead to blowouts, which are dangerous and can cause accidents or damage to your trailer and load.

The condition of your tires is directly tied to safety. Never compromise on this. If you notice any issues during your inspection, it’s better to replace the tire than risk a failure on the road.


When it comes to replacing your tires, don’t wait until it’s too late. If the tread is worn down past the legal limit (use the penny test – if you can see the top of Lincoln’s head, it’s time for new tires), or if there’s significant damage, get them replaced.

Always choose high-quality tires that are suitable for heavy-duty use. This might seem like a higher upfront cost, but it’s an investment in the safety and longevity of your dump trailer.

Your dump trailer is only as reliable as its weakest link. Don’t let that be your tires. Regular checks, proper inflation, and timely replacements are key to keeping your dump trailer rolling smoothly and safely.

By following these simple steps, you can ensure your tires are always in top condition, helping you avoid unnecessary breakdowns and ensuring your dump trailer operates safely and efficiently. This is just one aspect of dump trailer maintenance, but it’s a crucial one. Don’t overlook it.

Hydraulic System Upkeep

Maintaining the hydraulic system of your dump trailer is essential for its efficient operation. This system, which enables the raising and lowering of the dump bed, can be prone to issues if not properly cared for. Here, we’ll guide you through leak detection, battery connections, professional inspections, and more.

Temporary Fixes

Sometimes, you might find yourself in a situation where the hydraulic system isn’t functioning correctly. A common issue is the dump trailer bed getting stuck in the raised position. If this happens, a quick temporary fix involves adjusting the coils on the pump. Look for a square-shaped coil and a round-shaped coil. Loosening the nuts of each coil and switching them might allow you to lower the bed enough to take your trailer in for a professional inspection. This is a stop-gap measure, not a long-term solution.

Fluid Management

The lifeblood of your hydraulic system is the hydraulic fluid. For optimal performance, use the right type of fluid, typically automatic transmission fluid, due to its non-foaming properties. These properties are crucial because foaming can lead to decreased hydraulic system efficiency and increased wear on components.

When adding or replacing hydraulic fluid, ensure you don’t overfill the reservoir. Excess fluid can lead to leaks and other issues. Check your owner’s manual for the recommended fluid level and type. Regularly checking the fluid level should be part of your routine maintenance schedule, ideally every 1,000 hours of operation.

Leak Detection and Battery Connection

Leaks in the hydraulic system can often be traced back to a low battery charge. A fully charged battery is crucial for maintaining the right pressure within the system. If you notice any leaks, start by checking the battery’s charge and connections. Ensure the battery terminals are clean and secure, as poor connections can also lead to system issues.

If the problem persists or you’re unsure how to resolve it, don’t hesitate to seek professional help. A qualified technician can diagnose and fix problems that might be beyond the scope of basic maintenance.
