Set of 4 Trailer Tires ST205/75R15 8-Ply Load Range D - Durable Radial

In this review the Set of 4 Trailer Tires ST205/75R15 is evaluated for trailer owners who need a robust, high-capacity replacement. The bottom line: these Durun radial trailer tires combine an 8-ply Load Range D capacity with double steel belts and full nylon plies to deliver reliable load carrying up to 2150 lbs per tire and a stable, long-wearing tread for towing. They are aimed strictly at trailers and offer a sensible balance of durability and price for boat, camper, and travel trailer use.

Key Features

• Load Capacity: Rated to carry up to 2150 lbs per tire at maximum inflation, giving confidence when loading trailers for long trips.
• Construction: 8-ply Load Range D construction with double steel belts and full nylon plies improves tread stability and extends service life under heavy loads.
• Radial Design: Radial construction combines the robustness of bias-ply feel with improved longevity and a smoother ride for trailer towing.
• Service Limits: 65 PSI maximum inflation and a 15' rim diameter specification make fitment straightforward when matching existing trailer wheels.
• Durable Compound: High-quality rubber compound reduces rolling resistance and helps the tire resist wear on long highway tows.

Who It's For

This set is best for owners of boat trailers, campers, small travel trailers, or utility trailers who need an affordable, heavy-duty replacement tire capable of towing heavier loads. The tires suit those who want a radial trailer tire with reinforced belts and a higher load rating for regular towing or long-distance trips.

Those who should look elsewhere include drivers wanting tires for passenger cars or light trucks - these are intended for trailer use only - and buyers who need a different speed rating or a rim size other than 15' and rim width 5.5'. Wheels are not included, so budget for mounting and balancing if needed.
