I’ve noticed that with these tires, my trailer feels more stable on the road, especially when I’m hauling heavier equipment or supplies.
Another reason I find the ST175 80D13 necessary is their durability. They are built to withstand the unique stresses trailers face, like prolonged towing and occasional rough terrain. This gives me peace of mind knowing I’m less likely to experience tire blowouts or excessive wear, which can be dangerous and costly during a trip.

My Buying Guides on St175 80D13 Trailer Tire
When I first started shopping for the right trailer tire, I quickly realized how important it is to pick one that fits my specific needs. The ST175 80D13 trailer tire is a popular choice, and here’s what I learned during my search that might help you too.
Understanding What ST175 80D13 Means
Before buying, I made sure to understand the tire size code. “ST” stands for Special Trailer, which means this tire is designed specifically for trailers, not passenger vehicles. The “175” is the tire width in millimeters. “80” is the aspect ratio, indicating the height of the tire’s sidewall as a percentage of the width. “D” means it has a diagonal (bias-ply) construction, and “13” is the rim diameter in inches. Knowing this helped me ensure I got the right fit for my trailer wheels.
Why Choose a Bias-Ply (D) Tire?
I noticed the “D” in 80D13 stands for bias-ply construction. While radial tires are common, bias-ply tires like these offer some benefits for trailers—they tend to have stiffer sidewalls which help with stability when towing heavy loads. For my trailer, which carries a lot of weight, this was a key factor. However, I also considered my typical towing speed and distance because bias-ply tires might wear faster on highways compared to radials.
Load Capacity and Speed Rating
One of the first things I checked was the tire’s load rating. Trailer tires come with specific load capacities to ensure safety. The ST175 80D13 usually supports around 1,820 lbs per tire at 65 mph, but I double-checked the specs on the tire label to match my trailer’s weight. Overloading a tire can cause blowouts, so I recommend verifying this carefully.
Durability and Weather Resistance
Since my trailer is often parked outdoors, I wanted a tire that could handle different weather conditions without cracking or deteriorating quickly. I looked for tires with good UV protection and durable rubber compounds. Some brands also offer tires with enhanced sidewall protection, which is great if you often park on rough terrain.
Price vs. Quality
I found a wide price range when shopping. While it’s tempting to go for the cheapest option, I learned that investing a little more in a reputable brand gave me peace of mind about safety and longevity. Sometimes paying more upfront saves money in the long run by avoiding premature replacements.
Where to Buy and Warranty Considerations
I chose to buy from sellers that offered clear return policies and good warranties. Trailer tires can sometimes have manufacturing defects, so a warranty is important. Also, buying from a reliable dealer meant I got proper guidance and support if I had questions after purchase.
Final Tips From My Experience
- Always match the tire size exactly to your trailer’s requirements.
- Check the load and speed ratings carefully.
- Consider the type of terrain and weather exposure your trailer will face.
- Don’t rush—compare brands and reviews for reliability.
- Keep an eye on tire maintenance once installed (pressure, wear, etc.).
I hope my experience helps you find the perfect ST175 80D13 trailer tire for your towing needs!
