What Makes the Towstar STR ST175/80R13 the Best Choice for Your Trailer?

Advanced Radial Construction Technology: The ST175/80R13 size designation indicates a 175mm section width, 80% aspect ratio, and 13-inch rim diameter, creating an optimal balance between load capacity and ride comfort. This radial construction provides superior flexibility and heat dissipation compared to traditional bias-ply alternatives.

Enhanced Load Capacity Performance: With a C/6PR load range rating, these tires support up to 1,360 pounds per tire at a maximum inflation pressure of 51 PSI. This substantial load capacity makes them ideal for medium to heavy-duty trailer applications requiring dependable weight-bearing performance.

Superior Stability Features: The “solid center rib design ensures straight-line stability” during highway speeds, while the enhanced shoulder tread pattern provides better heat dissipation for longer and more even wear patterns. This combination significantly extends tire life and improves overall towing safety.

Advanced Engineering Features:

Four Circumferential Groove System: The innovative “four circumferential grooves assist with water evacuation”, dramatically reducing hydroplaning risk during wet weather conditions. This critical safety feature makes the Towstar STR particularly valuable for trailers operating in diverse climate conditions.

Enhanced Heat Dissipation Technology: The specialized shoulder tread design promotes superior heat dissipation, preventing dangerous tire overheating during extended highway use. This feature is especially important for boat trailers and RV applications that frequently encounter sustained high-speed operation.

Radial vs. Bias Construction Benefits: Unlike bias-ply tires, the radial construction provides better fuel economy, improved handling characteristics, and enhanced ride comfort while maintaining the structural integrity required for trailer applications.

Why Choose ST175/80R13 Size for Your Trailer Applications?

The ST175/80R13 tire dimensions create an overall diameter of approximately 24.9 inches when properly mounted and inflated, making this size perfect for:

• Medium-duty utility trailers carrying landscaping equipment and construction materials
• Boat trailers supporting watercraft up to 20 feet in length
• RV trailers and travel trailers require reliable highway performance
• Equipment trailers for commercial and recreational applications
• Cargo trailers are used in delivery and transportation services

The 13-inch rim diameter provides excellent ground clearance while maintaining proper weight distribution, ensuring your trailer operates safely within manufacturer specifications.

How to Maximize Performance from Your Towstar STR Tires

Proper Inflation Maintenance: The maximum PSI rating of 51 pounds requires consistent monitoring to ensure optimal load-bearing capacity and prevent premature wear. Check tire pressure monthly and before long trips, always measuring when tires are cold for accurate readings.

Load Distribution Best Practices: The C/6PR rating provides excellent load-bearing capability when weight is properly distributed across the trailer axle. Ensure your trailer’s cargo is balanced to prevent uneven tire wear and maintain safe handling characteristics.

Speed Rating Considerations: While these high-speed trailer tires can handle highway speeds, always observe posted speed limits and consider reducing speed in adverse weather conditions or when carrying maximum loads.
