Suntek HD Plus Tire Review

Finding the perfect heavy-duty tire set for your trailer can be tedious. However, it does not have to be.

Trailer tires should not be used on light trucks, and vice versa. Therefore, it is important to get the best possible ST tire set for your trailer to ensure its security performance.

While the tire market is oversaturated with various subpar trailer models, getting a good quality set does not have to be difficult.

Take the Suntek HD Plus for instance.

This tire is made for load durability, without sacrificing its controllability and all season traction.

But how is this achieved? What does the Suntek HD Plus offer for your trailer?

Let’s take a closer look at this phenomenal trailer tire, which you can find at Priority Tire.

Experience the Suntek HD Plus

The Suntek HD Plus is a highway terrain, all season tire made for trailers. It is manufactured with a stronger internal structure, features a symmetric ribbed tread design, and utilizes a durable compound. The combination of these elements ensures the tire’s exceptional performing capabilities.

So, what does the Suntek HD Plus actually provide?

All Season Traction

First off, great all season traction. The durable, all season compound is molded into a symmetric ribbed tread design. These guarantee the tire’s excellent surface traction in dry, wet, and even light winter conditions.

The stronger rubber materials manage to maintain their flexibility in versatile weather conditions. They avoid heat build-up across the tread area and ensure its year-round application. On the other hand, the ribbed pattern with the rib-edge and S-shaped sipes provides extra biting edges. They optimize the grip on the road surface throughout the year.

Additionally, the four circumferential grooves of the Suntek HD Plus prevent hydroplaning. They manage to channel water and slush through the footprint, preventing them from blocking the surface contact. In this manner, water and slush stuck on the road surface cannot cause the tire’s hydroplaning.

Optimizing Controllability

The flat footprint and the ribbed tread design, along with the stronger shoulders, enhance the trailer’s controllability. Improving the tread elements and their road contact allows the tire to ensure its constant surface contact.

These tread elements ensure the tire’s surface contact throughout its performance. The footprint closely follows the road surface at all times, boosting the steering responsiveness and driving stability. Not only does this ensure the towing vehicle’s control over the trailer, but it also effectively minimizes the possibility of trailer swaying.

What do we mean by that?

The stability the structure and road contact offer places the Suntek HD Plus firmly on the road surface. This significantly minimizes the possibility of side forces (pressure affecting the trailer) from moving the trailer side to side behind the towing vehicle.

As a result, the tire is able to promote a safer towing experience.

Improved Load Durability

The most important feature of any trailer tire is its load capacity. They have to maintain their ideal shape under heavy loads, without ruining their handing or traction in the process.

In other words, the reinforced radial internal structure withstands heavy loads with ease. The Suntek HD Plus does not deform during its heavy-duty application. This makes the tire perfect for trailers, which are used for heavy load transportation.


  • Stronger all weather traction
  • Improved controllability
  • Prevention of trailer sway
  • Upgraded load capacity


  • Only available in one size 225/75R15

Product Information

The Suntek HD Plus is a trailer tire that provides exceptional all season traction and handling. This model is available in only one size, 255/75R15, which is a bit of a letdown. However, if your trailer carries this size, you are in luck!

This features a 14ply structure and comes with a 124/121M load and speed rating, and a G load range.

But what does this mean?

Tires with a 124/121 load rating can handle 3527 pounds per tire if two tires are mounted on one axle, and 3297 pounds per tire if four tires are mounted on one axle. Additionally, the G load range indicated its 14 ply construction, which optimizes the overall load handling ability.

On the other hand, the M speed rating notes its speed durability. In other words, the tire can withstand a speed up to 81 mph. This makes the Suntek HD Plus a bit slow, but that is normal for ST tires.

Is the Suntek HD Plus the Right Tire for You?

To decide if the Suntek HD Plus is the right tire for you or not, you need to take a look at what you are putting your trailer through.

Does it need heavy load capacity? Does it have problems with swaying? Did the previous ST tires have traction problems?

The Suntek HD Plus is an excellent choice if you are looking for heavy-duty tires, which offer great all season traction and handling.

That said, this model’s biggest flex is its load durability, which is ensured with the radial structure. You can rest assured that its construction will be able to handle anything you throw at it – or on the trailer.
