1. Carlisle Radial Trail HD: Best Overall
The Carlisle Radial Trail HD is our top pick for ST175/80R13 trailer tires. In our evaluation, its radial construction provides superior stability and heat dissipation compared to bias-ply tires, making it ideal for highway towing. Owner feedback consistently highlights long tread life and resistance to sidewall damage, even under maximum load. Load Range C with a 1360 lb capacity per tire meets the needs of most single-axle trailers.
However, this tire commands a higher price than budget alternatives. If you tow only short distances at low speeds, a bias-ply tire may offer better value. We recommend the Radial Trail HD for those who frequently tow on highways or need maximum durability. Skip it if your trailer sees only occasional, low-speed use and you are on a tight budget.
- Radial construction for better stability and heat dissipation at highway speeds
- Reinforced sidewalls resist cuts and abrasions from road debris
- Consistent owner reports of long tread life even under heavy loads
Pros: Excellent highway stability; Durable sidewall construction
Cons: Premium price point compared to bias-ply options
2. Goodyear Endurance: Premium Pick
The Goodyear Endurance stands out with its Load Range D rating, offering a generous 1760 lb capacity per tire. In our research, this tire is a favorite among owners of heavier trailers due to its robust construction and low heat buildup. The advanced tread compound is designed to resist punctures, and owner feedback confirms exceptional durability even on rough roads.
On the downside, the stiffer sidewalls can make the ride slightly harsher, and the price is among the highest in this size. If your trailer is lighter than 3000 lbs GVWR, you may not need the extra capacity. We recommend the Endurance for those towing near the weight limit or who prioritize maximum safety margin. Skip it if you want a smoother ride or lower upfront cost.
- Higher load range D for heavier trailers and extra safety margin
- Advanced tread compound reduces heat buildup and extends wear
- Widely praised for puncture resistance and long service life
Pros: Higher load capacity; Excellent puncture resistance
Cons: Stiffer ride may transmit more road vibration to the trailer
3. Kenda Karrier Loadstar K399: Best Value
The Kenda Karrier Loadstar K399 is a bias-ply tire that delivers solid value for budget-conscious buyers. Our analysis of owner feedback shows it performs well for local towing and on unpaved roads, with a deep tread that grips loose surfaces. Load Range C provides adequate capacity for typical utility and boat trailers.
However, bias-ply construction means it is not ideal for long highway trips at high speeds, as heat buildup can accelerate wear. If you tow primarily at low speeds and want to save money, this is a great choice. We recommend it for light-duty, occasional use. Skip it if you frequently tow on highways or need maximum tread life.
- Bias-ply design offers excellent stability at lower speeds and lower cost
- Deep tread pattern provides good traction on loose surfaces
- Many owners report satisfactory tread life for the price
Pros: Affordable price; Good traction on gravel
Cons: Not recommended for sustained highway speeds above 65 mph
4. Taskmaster Premium ST: Budget Friendly
The Taskmaster Premium ST is one of the most affordable ST175/80R13 tires available. In our evaluation, it performs adequately for light-duty applications like small utility trailers used around town. Owner feedback indicates that it is easy to mount and balances well for the price.
However, the trade-off is reduced durability and tread life. Many owners report needing replacement after a couple of seasons of regular use. We do not recommend this tire for highway travel or heavy loads. Skip it if you tow long distances or want a tire that will last several years.
- Very low price point makes it accessible for tight budgets
- Bias-ply construction suitable for low-speed, short-distance towing
- Basic tread pattern adequate for dry pavement
Pros: Extremely affordable; Lightweight and easy to mount
Cons: Shorter tread life compared to premium options; Not for highway use
5. Maxxis M8008 ST Radial: Radial Upgrade
The Maxxis M8008 ST Radial offers a solid radial option at a mid-range price. In our research, it provides good stability and fuel efficiency for highway towing, with many owners reporting even tread wear over time. The Load Range C capacity matches most single-axle trailers.
Availability can be an issue, and some owners have noted that the tire is slightly noisier than the Carlisle. We recommend it for those who want a radial tire but find the Carlisle or Goodyear out of budget. Skip it if you need the highest load capacity or prefer bias-ply for low-speed use.
- Radial design for improved fuel economy and longer tread wear
- Sturdy sidewalls resist flexing under load
- Positive owner feedback on highway stability
Pros: Good highway manners; Longer tread life than bias-ply tires
Cons: Not as widely available as some competitors
6. Trailer King ST Radial: Entry Radial
The Trailer King ST Radial is an entry-level radial tire that offers a step up from bias-ply without breaking the bank. Our evaluation of owner feedback shows it provides acceptable highway stability and a smoother ride than bias-ply tires. It is a popular choice for budget-minded owners who tow occasionally on highways.
However, some owners report premature wear or sidewall issues after a few thousand miles. We recommend it only for light loads and moderate use. Skip it if you need a tire for heavy towing or long-distance travel.
- Affordable radial option for those wanting radial benefits on a budget
- Decent highway stability for the price
- Lightweight design aids fuel efficiency
Pros: Radial benefits at low cost; Good value for money
Cons: Lower overall durability reported by some owners; Tread life shorter than premium radials
7. Greenball Towmaster ST: Specialty Use
The Greenball Towmaster ST is designed for trailers that venture off pavement, such as boat launches or construction sites. In our research, its aggressive tread pattern provides grip on mud and gravel, and the reinforced lugs help resist damage from sharp rocks. Owner feedback confirms it performs well in challenging terrain.
However, on paved roads, the tread is noisy and wears quickly. This tire is not ideal for highway use or as a primary road tire. We recommend it only for those who regularly tow on unimproved surfaces. Skip it if most of your towing is on asphalt.
- Bias-ply tire with a focus on off-road and rough terrain use
- Aggressive tread pattern for traction on soft surfaces
- Reinforced shoulder lugs resist cuts
Pros: Good off-road traction; Reinforced lugs for durability
Cons: Noisy on pavement; Faster tread wear on hard surfaces
Frequently Asked Questions
What does ST175/80R13 mean?
ST stands for Special Trailer, indicating the tire is designed for trailer use only. 175 is the section width in millimeters, 80 is the aspect ratio (sidewall height is 80% of width), and R13 means radial construction with a 13-inch rim diameter.
Can I use passenger car tires instead of ST trailer tires?
No. ST trailer tires have stronger sidewalls and higher load capacities than passenger tires. Using passenger tires on a trailer can lead to overheating, blowouts, and unsafe towing. Always use ST tires for trailers.
What is the difference between Load Range C and D?
Load Range indicates ply rating and maximum air pressure. Load Range C typically has a 6-ply rating and max pressure of 50 psi, while Load Range D has an 8-ply rating and max pressure of 65 psi. D tires can carry more weight but ride stiffer.
How often should I replace ST175/80R13 trailer tires?
Replace tires every 5-6 years regardless of tread depth, or sooner if you see cracks, bulges, or excessive wear. Check pressure and condition before each trip. Tread life varies with load and speed.
What is the correct tire pressure for ST175/80R13 trailer tires?
Always inflate to the maximum pressure molded on the sidewall (typically 50 psi for Load Range C, 65 psi for D). Underinflation causes heat buildup and blowouts. Check pressure when tires are cold.
Our Verdict
After researching and comparing the top ST175/80R13 trailer tires, the Carlisle Radial Trail HD is our top pick for its excellent highway stability and durability.
