What Makes the RubberMaster S380 Your Best Choice for 4.80-8 Trailer Tires?

The RubberMaster S380 (P819) is a high-speed trailer tire that features five circumferential ribs that are wear-resistant and designed for any road and all weather conditions. This innovative design sets the foundation for superior performance, making it an ideal choice for boat trailers, utility trailers, and small cargo applications.

Our 4.80-8 B/4PR tire specifications include a robust 4-ply rating construction that provides excellent load-bearing capacity while maintaining optimal flexibility for smooth rides. The B load range rating ensures these tires can handle substantial weight distributions without compromising safety or performance standards.

Key Performance Features:

Five Circumferential Ribs Design: The tire’s advanced tread pattern incorporates five strategically positioned ribs that enhance stability during highway speeds and provide exceptional wear resistance. This design element significantly extends tire life compared to conventional trailer tire options.

Superior Water Dispersal Technology: The zig-zag longitudinal grooves disperse water out of the tire’s tread and reduce the aquaplaning risk. This critical safety feature makes the RubberMaster S380 particularly valuable for trailers operating in wet weather conditions or coastal environments where water hazards are common.

All-Weather Performance: Unlike standard tires that struggle in varying conditions, these all-weather trailer tires maintain consistent traction across dry, wet, and moderate winter conditions, making them perfect for year-round trailer use.

Why Choose 4.80-8 Size for Your Trailer Application?

The special trailer tire size 4.80-8 has an overall diameter of right around 16-inches when the tire is mounted on the rim and inflated. This compact profile makes it particularly suitable for:

• Boat trailers requiring reliable water launch and retrieval performance
• Utility trailers for landscaping and home improvement projects
• Small cargo trailers for recreational and commercial applications
• ATV trailers and specialized transport equipment

The 4.80-8 tire dimensions provide an optimal balance between ground clearance and load capacity, ensuring your trailer maintains proper weight distribution while delivering smooth operation across various terrain types.

How to Maximize Performance from Your RubberMaster S380 Tires

Proper Inflation Maintenance: The maximum PSI rating of 60 lbs requires consistent monitoring to ensure optimal performance. We recommend checking tire pressure monthly and before long trips to maintain the tire’s load capacity and prevent premature wear.

Load Distribution Best Practices: The B/4PR rating indicates these tires can handle significant loads when properly distributed. Always ensure your trailer’s weight is evenly balanced to maximize tire life and maintain safe handling characteristics.

Regular Inspection Schedule: Professional tire maintenance includes visual inspections for wear patterns, sidewall damage, and tread depth measurements. This proactive approach helps identify potential issues before they become safety concerns.
