Hercules Power STR 235-85R16 Trailer Tires Review

Hercules Power STR 235/85R16 Trailer Tires Review


The size of this tire is 235/85R16 128L. It has a 235mm surface width, with a tire thickness of 85% compared to the width. Besides, it fits the wheels whose diameter is 16 inches.

Moreover, the maximum payload that this tire can load is 3968 pounds at 95 PSI.


This tire consists of two main materials synthetic rubber and steel. In particular, synthetic rubber accounts for the majority of tires, and steel is used to produce the inside steel belts to support the tire.

Rubber is an extremely elastic material that helps reduce shock and increase adhesion to the road surface when using vehicles. Besides, the durable stainless steel helps maximize support and extend the tire life.


Structurally, since this is a radial steel-belted tire, it has steel straps running in the direction perpendicular to the centerline of the tire.

These steel belts work to strengthen the wheel, thereby balancing the tire’s pressure with the vehicle weight that the wheel can load.

Next, the tread pattern on the outside of the tire is symmetric style, in which the centerline of the tire is the symmetrical center, and the two sides look like reflecting each other.

This tread pattern is quite popular because of its flexibility. It’s also called a “multi-directional” pattern because when you change or rotate in different directions, it still keeps the wheel stable.


As mentioned above, the proper materials and special designs create outstanding features for the tire itself.

One of the features that we can’t ignore is versatility. Besides the flexibility in changing direction, this tire can be used under many different weather conditions.

It can hold onto the road surfaces no matter whether they’re dry or wet. At the same time, extreme weather conditions such as the cold air in winter can’t challenge this tire.

Moreover, Hercules Power STR 235 / 85R16 is quiet and enduring. It won’t distract you while driving just because of the annoying sounds.


  • Flexibility

1. Is Hercules Power STR 235/85R16 Steel-belted Or Ply?

Hercules Power STR 235 / 85R16 128L is a radical steel-belted tire. The design of this type will help the tire balance the inside pressure and outside weight to have safe journeys and ensure durability for the trailers.

2. Is It Suitable For Car/Truck?

You can assemble this tire for a car/truck, and your vehicles may work. However, I recommend you shouldn’t do that.

Each type of tire for different vehicles will have particular designs to support your car, truck, etc. optimally. If you don’t use the right type of vehicle, it’s easy to affect their durabilities adversely, and most importantly, it’s dangerous when you’re on trips.

3. How Should I Preserve It?

First, when the tires aren’t in use, it’s best to keep them or your trailers in storage as the UV ray from the sun is one of the leading causes of tire damage. At the same time, this also helps reduce the negative impact of cold airflow in winter.

Also, you should use the cover when storing the tires to increase their protectability.

Secondly, If possible, use the jack under the trailer to lift the tires off the ground a bit. This way helps minimize wear and tear effectively.

Next, always keep the inside pressure of the tire at the standard. Excessive pumping and insufficient pressure will do the same will cause it to wear out quickly.

4. Do I Need To Balance All The Tires?

The answer is yes.

Balancing the tires will help your vehicles to operate more stably and safely. Besides, the evenly distributed gravity on the wheels will limit one of them is wear out before the others.

Last but not least, I recommend using one type of tire for all wheels, particularly not combining Radical and Bias tires.


I hope that my Hercules trailer tires review has given you the most useful information about Hercules Power STR 235/85R16 128L.

Overall, this is a product with all the advantages of becoming the best horse trailer tires, such as being durable, flexible in moving, quiet in operating, and so on.
