When it comes to towing safety, your trailer tires are one of the most critical components. Proper maintenance isn’t just about keeping your trailer on the road—it’s also about ensuring the safety of yourself and others. Unfortunately, many trailer owners overlook tire care until it’s too late, often resulting in expensive blowouts or, worse, accidents.
This guide will walk you through everything you need to know about trailer tire maintenance, from understanding tire types to implementing practical tips for preventing blowouts.
What You Need to Know About Trailer Tires
Before tackling maintenance, it’s important to understand the basics of trailer tires and their unique requirements. Unlike regular vehicle tires, trailer tires are designed to handle specific loads and conditions that demand specialized care.
Types of Trailer Tires
There are two main types of trailer tires:
- ST Tires (Special Trailer Tires): These are specifically designed for trailers and offer stiff sidewalls to handle heavy trailer loads without swaying. They are built for towing, not for standard vehicle use.
- LT Tires (Light Truck Tires): Occasionally used for trailers, LT tires are more flexible than ST tires. However, they may not be ideal for larger, heavier trailers due to their less robust construction.
For most trailer owners, ST tires are the better choice due to their durability and load-bearing capabilities.
How to Read Tire Sidewall Markings
Deciphering the information on the sidewall of your tires can provide a wealth of knowledge. Here’s what to look for:
- Size Code: Information like “ST205/75R15” denotes the tire type, width, aspect ratio, and wheel diameter.
- Load Range: Indicates the tire’s load-carrying capacity. For example, Load Range C is sufficient for light trailers, while Load Range E is typically used for more substantial loads.
- Max PSI: This specifies the recommended maximum inflation pressure for safe operation.
Understanding these details can help you select the right tires for your trailer and determine if your current tires meet your needs.
Tips to Prevent Blowouts & Extend Tire Life
Tire blowouts are not only inconvenient but also dangerous. Here are some actionable tips to keep your trailer tires in peak condition:
1. Maintain Proper Inflation
Over-inflated or under-inflated tires are a leading cause of blowouts. Always check and maintain tire pressure according to the manufacturer’s specifications. Use a high-quality tire pressure gauge and adjust the PSI when tires are cold for the most accurate reading.
2. Avoid Overloading Your Trailer
Each tire has a specific load capacity. Overloading your trailer increases the strain on the tires, potentially leading to structural failure. Refer to the Gross Vehicle Weight Rating (GVWR) of your trailer and ensure that your tires are equipped to handle the load you’re towing.
3. Monitor Tire Age and Replace When Needed
Tires degrade over time, even if they appear to be in good condition. An often-cited rule of thumb is to replace trailer tires every 5-7 years, regardless of mileage. Check the DOT code on the sidewall to determine the tire’s manufacturing date, and factor the age into your replacement plan.
4. Perform Regular Inspections
Before every trip, inspect your tires for visible damage, such as cracks, bulges, or punctures. Look for uneven wear patterns, which may indicate improper inflation or alignment issues. Regular inspections can catch small problems before they escalate into major ones.
5. Ensure Proper Wheel Alignment
Misaligned trailer wheels can cause uneven tire wear, affecting both tire performance and towing safety. Schedule periodic alignment checks with a professional maintenance provider to ensure your trailer’s wheels are properly aligned.
6. Store Your Trailer Tires Correctly
If your trailer will sit idle for an extended period, proper storage can protect your tires from weather damage:
- Keep your trailer in a shaded or indoor area to avoid direct sunlight, which can degrade rubber.
- Use tire covers to shield tires from UV rays.
- Inflate tires to their recommended pressure during storage to maintain their shape and prevent flat spots.
Stay Safe & Keep Rolling
Maintaining your trailer tires is essential for safety, cost savings, and peace of mind. By following these simple yet effective tips, you can extend the life of your tires and avoid the headaches that come with preventable blowouts.
