Trailer tires are one of the most important components of a safe, stable haul, and the most frequently neglected. Unlike standard vehicle tires, trailer tires face unique stresses from heavy loads, extended periods of disuse, and sharp cornering. When they fail, the consequences can be severe: blowouts, uneven handling, or costly delays.
In this guide, we’ll show you how to spot and solve common trailer tire problems, understand why they happen, and how to prevent them before your next trip.
Troubleshooting Trailer Tire Problems
If you already suspect a tire issue or notice a problem while on the road, this section will help you quickly identify and resolve it.
1. Uneven Tire Wear
What it looks like: Tread is worn more on one side, in the center, or along the edges.
Causes: Misaligned axles, over/under-inflation, or worn suspension parts.
Fix: Start by checking tire pressure on all wheels and adjust according to the trailer’s load and manufacturer’s recommendations. Uneven wear on just one tire may point to a bent axle or misalignment, which should be inspected and corrected by a professional. If the wear is edge-to-edge or across multiple tires, the issue may be systemic, such as sagging leaf springs or worn suspension bushings. Replacing these components can restore proper geometry and extend tire life.
2. Tire Blowout
What it looks like: A sudden loud pop followed by tire failure, often leaving shredded rubber behind.
Causes: Overloading, under-inflation, worn or dry-rotted tires, or excessive heat from long-distance towing.
Fix: Safely replace the blown tire with a spare that matches the load and size requirements. If one tire blows, check the others immediately; they may be in a similar condition. Going forward, monitor your load weight carefully, check tire pressure before every trip, and avoid driving on old or weathered tires. Heat is also a major factor, so take breaks during long hauls and avoid underinflated tires that generate excess friction.
3. Dry Rot or Cracking
What it looks like: Cracks in the sidewall or tread surface, sometimes small and spiderweb-like or deep and splitting.
Causes: UV exposure, rubber aging, and extended storage without movement.
Fix: Tires showing signs of dry rot should be replaced, even if they still have plenty of tread. Rubber degrades over time and becomes brittle, which makes it prone to blowouts. Store the trailer in a garage, under a carport, or use tire covers to block UV rays. During long periods of inactivity, move the trailer occasionally to prevent stress on one part of the tire and reduce cracking from static pressure.
4. Tires Wearing Out Too Quickly
What it looks like: Tires appear bald or badly worn after just a few trips or low mileage.
Causes: Cheap tires, improper inflation, or an unevenly loaded trailer.
Fix: Replace low-quality or mismatched tires with trailer-specific (ST-rated) models from reputable manufacturers. Make sure all tires are inflated to their correct pressure, based on both the manufacturer’s recommendation and your current load. Use a weight distribution system or trailer scale if needed to ensure even loading across the axles. Tires wearing too quickly is often a sign that stress is being placed unevenly on your trailer, and the fix could be as simple as rearranging cargo.
5. Vibration or Wobble While Towing
What it feels like: A shaky or wobbly sensation at certain speeds, possibly felt through the tow vehicle.
Causes: Out-of-balance tires, bent or damaged rims, or worn wheel bearings.
Fix: Vibrations during towing usually point to a mechanical imbalance. Start by having the tires balanced at a tire shop that handles trailer wheels. Check for dents, flat spots, or warping in the rims; even a small bend can throw off rotation. Spin each wheel by hand while the trailer is jacked up and listen or feel for grinding or looseness. If the hub wobbles or makes noise, it’s time to replace the wheel bearings and possibly the hub assembly.
Why Trailer Tires Fail
Many trailer tire problems can be traced back to one or more of the following causes:
Under or Overinflation
Incorrect tire pressure is one of the most common causes of trailer tire failure. When tires are underinflated, they flex more than designed, generating excess heat as the sidewalls bend and move. This heat buildup can weaken the tire structure and lead to dangerous blowouts, especially at highway speeds. Overinflated tires are also a problem; they ride stiff, reduce traction, and wear out faster in the center of the tread. Both conditions put unnecessary stress on the tire and reduce its lifespan. Always check tire pressure when the tires are cold and adjust according to the trailer manufacturer’s guidelines.
Overloading
Exceeding the trailer’s weight rating places more pressure on each tire than it was built to handle. Overloaded tires are more likely to overheat, wear unevenly, and fail under stress. This can lead to sudden blowouts or damage to the trailer’s axle and suspension. Many drivers overload without realizing it, especially when hauling equipment or heavy cargo. Always verify the combined load does not exceed the Gross Vehicle Weight Rating (GVWR) and that each tire’s load rating is appropriate for the total weight it’s supporting.
Age & Storage Conditions
Tires naturally degrade over time, even if they’re not in regular use. UV rays, temperature changes, moisture, and long periods of inactivity all contribute to dry rot and cracking. Storing a trailer outdoors without protection can significantly shorten a tire’s lifespan, even if the tread still looks good. Rubber becomes brittle with age, making the tire more susceptible to cracking and failure under load. Most trailer tires should be replaced every 5 to 7 years, regardless of mileage, especially if they show signs of aging.
Poor Maintenance
Neglecting basic tire maintenance can lead to premature failure and avoidable repair costs. Skipping regular pressure checks, ignoring tread wear, or failing to inspect the sidewalls can let small problems grow into major ones. Unlubricated or worn wheel bearings can cause uneven tire stress and heat buildup. Loose lug nuts or neglected hub components can create wobbles or alignment issues that wear tires unevenly. Maintenance shouldn’t take up much time, but it can dramatically improve tire performance and safety.
Cheap or Mismatched Tires
Not all tires are created equal. Using passenger car tires or mixing different tire brands, sizes, or load ratings can cause poor handling, uneven wear, and early failure. Trailer-rated tires are specifically built with stiffer sidewalls and higher load capacities to handle towing forces. Choosing low-cost or mismatched tires might save money upfront, but it often results in more frequent replacements and safety risks on the road.
Signs of Trailer Tire Problems
Look for these signs before and during your trip:
- Cracking, splitting, or visible dry rot
- Uneven or excessive tread wear
- Vibration or wobbling while towing
- Bulges or blisters in the sidewall
- Frequent air loss or slow leaks
- Tires older than 5–6 years, even if the tread looks good
How to Prevent Trailer Tire Problems
Check Tire Pressure Before Every Trip
Maintaining the correct tire pressure is the single most important thing you can do to extend the life of your trailer tires. Always use a quality tire gauge and check pressure when the tires are cold. Adjust according to the manufacturer’s specifications, which are usually listed on the tire sidewall or trailer placard.
Use a Tire Pressure Monitoring System (TPMS)
A TPMS provides real-time updates on each tire’s pressure and temperature while you’re driving. This helps you catch slow leaks, overheating, or pressure drops before they turn into dangerous blowouts on the road.
Keep Your Trailer Tires Covered When Stored Outdoors
UV rays and weather exposure accelerate tire aging. Use tire covers or park the trailer in a shaded area to reduce the risk of dry rot and cracking. Even short-term exposure to direct sunlight can cause damage over time.
Rotate and Inspect Tires Regularly
Just like with a vehicle, rotating your trailer tires helps ensure even wear. While rotating, take time to inspect each tire for signs of wear, damage, or aging. Catching these early can prevent roadside breakdowns.
Invest in Trailer-Rated Tires from Reputable Brands
Not all tires are the same. Always choose trailer-specific tires (designated ST) that are rated for higher load capacity and pressure. Four Winds Trailers supplies premium ST-rated tires with consistent tread patterns, reinforced sidewalls, and load ratings matched to your trailer’s axle configuration. Choosing the right tires from the start helps reduce wear, improve towing stability, and lower your risk of tire-related breakdowns.
Make Sure Your Load Is Balanced & Within the Trailer’s Rated Capacity
Uneven or excessive weight puts stress on individual tires, leading to uneven wear or blowouts. Distribute cargo evenly and stay within the weight ratings for your trailer and tires. Use a scale if you’re unsure.
Replace Tires Every 3-5 Years Regardless of Tread
Even if the tread looks fine, rubber degrades over time. Most tire manufacturers recommend replacing trailer tires every 3 to 5 years, even if they haven’t reached the mileage limit. Age-related issues like dry rot can cause sudden failures.
