No 01: Load Capacity Variations

If you go with 6 ply trailer tires instead of 4 ply tires, you’ll notice significant variations in their load capacity. The ply rating of a tire refers to the number of layers of fabric or cords used in its construction, and it directly affects the tire’s ability to handle heavy loads. A higher ply rating means a stronger tire that can withstand greater weight.

In the case of 6 ply trailer tires, their load capacity is typically higher compared to 4 ply tires. This means that they can carry heavier loads without compromising safety or performance. The increased load capacity of 6 ply tires is particularly beneficial for trailers that haul heavy loads or are used for commercial purposes.

4 ply trailer tires are usually used in residential settings, where lighter loads and less frequent use are the norm. They are cheaper than 6 ply tires, making them an attractive option for recreational trailers.

No 02: Tire Weight and Compatibility with Rims

4-ply tires are typically lighter in weight than 6-ply tires. This can be advantageous for trailers that need to be maneuverable or for smaller vehicles that require lighter loads.

However, it is important to note that the weight of a tire also affects its compatibility with rims. While 4-ply tires may be lighter in weight, they may not be suitable for all rims.

Some rims may be designed specifically for use with 6-ply tires, and attempting to use a 4-ply tire on such a rim could result in compatibility issues, reduced performance, or even safety risks. Therefore, trailer owners should always consult the manufacturer’s recommendations when selecting tires and rims.

No 03: Durability and Longevity

A vehicle’s tires should be durable and long-lasting, as they can greatly affect your vehicle’s performance and lifespan. Regarding 4 ply and 6 ply trailer tires, durability and longevity are key considerations.

Ply is the number of layers of fabric or rubber used in the tire construction. 6 ply indicates a tire with six layers and 4 ply indicates a tire with four layers.

Generally, 6 ply trailer tires are more durable and long-lasting than their lower ply counterparts. The additional layers provide extra strength and resistance to punctures and damage, making them ideal for heavy loads and rough terrains.

Investing in 6 ply trailer tires ensures that your tires can withstand the demands of towing and provide reliable and safe performance for an extended period.

No 04: Handling and Ride Quality

When comparing 4 ply and 6 ply trailer tires, you must consider the impact on handling and ride quality. 4 ply tires, also known as bias ply tires, are constructed with multiple layers of rubber and fabric cords running diagonally across the tire. This design provides a stiffer sidewall, resulting in better stability and improved handling.

However, some trailer owners may notice decreased stability and bumpier ride when compared to heavier 6-ply tires.

On the other hand, 6 ply trailer tires, also known as radial tires, have steel belts running across the tire, which allows for a more flexible sidewall. This flexibility provides a smoother ride, absorbing bumps and vibrations on the road.

No 05: Tire Size Considerations

The size of the tire affects various aspects of the trailer’s performance, including its handling and ride quality. A larger tire size, such as a 6 ply tire, generally offers better stability and load-carrying capacity compared to a ply tire. It can provide enhanced traction and control, especially when towing heavy loads.

4 ply tire size is popular for lighter loads, as it offers a smoother ride and is easier to maneuver. Smaller tires also tend to be more affordable than their 6 ply counterparts.

No 06: Inflation Pressure Impact

With regards to 4-ply vs. 6-ply tires, inflation pressure can affect both options. While 6-ply tires have a higher load capacity than 4-ply tires, they may also require higher inflation pressure to support the weight of your trailer. However, overinflating your 4-ply tires may help compensate for their lower load capacity.

No 07: Vehicle Weight Distribution

Vehicle Weight Distribution

To ensure a smooth and stable towing experience, make sure your vehicle weight is evenly distributed among all four wheels. 6-ply tires are generally recommended for heavier loads and vehicles with unbalanced weight distribution, providing increased durability and load capacity.

However, 4-ply tires may be suitable for lighter loads and properly balanced weight distribution. 

Here are some key factors to consider about vehicle weight distribution:

  • Load distribution: Make sure your cargo’s weight is properly distributed within the trailer. Avoid placing all the weight at the front or rear, as this can cause imbalance and affect the trailer’s stability.
  • Tongue weight: The tongue weight, or the downward force exerted on the hitch by the trailer, should be around 10-15% of the total trailer weight. This helps maintain proper balance and control during towing.
  • Tire capacity: Check the load capacity of your tires and ensure that it is sufficient to handle the weight of your vehicle and trailer. Overloading the tires can lead to tire failure and compromise safety.
  • Suspension system: Consider upgrading your vehicle’s suspension system to handle the additional weight of towing. This can improve stability, control, and overall towing performance.

A properly distributed load can greatly impact the performance and safety of your trailer. Uneven weight distribution can cause excessive wear and tear on tires, leading to blowouts or even accidents.

No 08: Sidewall Strength and Safety

Ensure your vehicle’s sidewall strength is sufficient to handle the weight and stress of towing, as a study found that sidewall failures are responsible for a significant number of tire blowouts during towing.

The sidewall of a tire plays a crucial role in maintaining stability and providing protection against external forces. The sidewall is subjected to increased pressure and strain when towing a heavy load.

Additional layers in 6-ply tires provide extra reinforcement, making them more resistant to wear and punctures. This added strength can be critical for heavy-duty hauling and long-term use.

On the other hand, 4-ply tires may be sufficient for lighter trailers or occasional use, but they may need to be more reliable in high-stress situations. It’s important to note that sidewall strength is just one factor in overall tire safety.

No 09: Rolling Resistance

Considering 4 ply and 6 ply trailer tires, it’s important to consider rolling resistance. Rolling resistance refers to the force required to keep the tires rolling as your vehicle moves. Tires with high rolling resistance require more energy from your engine, leading to increased fuel consumption.

On the other hand, tires with low rolling resistance reduce the energy needed to keep your vehicle in motion, resulting in improved fuel efficiency.

While 4 and 6 ply tires can provide adequate sidewall strength and safety, 4 ply trailer tires tend to have lower rolling resistance due to their construction and materials.

No 10: Fuel Efficiency

When comparing 4 ply and 6 ply trailer tires, fuel efficiency is an important factor to consider. Generally, 4 ply tires are lighter in weight and require less energy to rotate, which can result in better fuel efficiency.

However, the difference in fuel efficiency between a 4 ply and 6 ply tire may be negligible for some towing situations. Factors such as driving habits and vehicle aerodynamics can also impact fuel efficiency.
