Difference between 8 ply vs 6 ply trailer tires

8 Ply vs 6 Ply Trailer Tires

The main difference between 6 and 8-ply trailer tires is their maximum loading capacity and safety. The load range capital marks of a trailer tire refer to the ply rating of that tire. For example, a load range ‘B’ indicates it comes with a 4-ply tire with a maximum loading capacity of 35 psi.

A load range ‘C’ means it comes with 6 ply tires with a maximum loading capacity of 50 psi. On the other hand, a tire with a ‘D’ load range indicates it is an 8-ply tire with a maximum loading capacity of 65 psi. Similarly, an ‘F’ load range tire comes with 10 plies with maximum loading capacity. 

6-ply tires meaning 

A 6 ply trailer tire is similar to a ‘C’ load range trailer tire. A 6 ply trailer tire has 6 layers on its sidewalls to strengthen its maximum loading capacity. You can carry its recommended maximum loads at 50 psi without blowing out the tire.

8-ply tires meaning

An 8-ply trailer tire is similar to ‘D’ load range trailer tires. It has eight layers on its sidewalls to provide strongest tires that are suitable for heavy-duty performance. However, you can carry maximum loads at 65 psi with safety.

Comparative study on 8-ply and 6-ply trailer tires 

The difference between 8-ply and 6-ply trailer tires is in their maximum loading capacity. An 8-ply rating trailer tire comes with added extra loading capacity than a 6-ply trailer tire.

In addition, you can carry large and heavy loads with maximum safety with 8-ply trailer tires. An 8-ply trailer tire is more suitable for towing performance than a 6-ply for its strong built-in sidewall structure. 

Which one is best for your trailer 8-ply or 6-ply tires?

Choose the trailer tire ply rating or load range based on your trailer requirements. Heavy loads need a higher ply rating than less heavy loads. For example, if you often need to carry heavy or valuable loads from place to place, then 8-ply tires are best for your trailer.

Containing more plies on the sidewalls makes your trailer tire strong enough to carry its maximum loads. On the contrary, pick 6-ply tires if you need to transport less heavy loads on your trailer. Suppose your current tire has 6-ply in its construction with extra loading capacity; it may not be necessary to go for an 8-ply tire.

If you want to upgrade to an 8-ply tire just for its added loading capacity, it can be a waste of money. Always consider your trips and required loading capacity before choosing the ply rating of your trailer tires. 

Advantages and disadvantages of 8-ply and 6-ply trailer tires
