Carlisle Sport Trail LH Bias Trailer Tire ST185/80D13 LRC - Durable

In this review the Carlisle Sport Trail LH Bias Trailer Tire ST185/80D13 LRC is assessed as a practical, purpose-built option for towable utility and boat trailers; the single biggest reason to consider it is its balance of rugged sidewall protection and lower rolling resistance that helps reduce heat build-up and improve fuel efficiency on shorter-distance or infrequent hauls. The reviewer found it best suited to owners who need a dependable, trailer-specific tire with a clear load rating and recommended 50 PSI rather than drivers seeking the longest possible highway service life or a radial tire feel in all conditions.

Key Features

• Bias ply construction: Provides a sturdy sidewall that guards the tire and wheel from punctures and bruises during loading and trailering.
• Zigzag tread grooves: Funnel water out of the tread to improve wet traction and reduce the risk of hydroplaning on wet ramps and access roads.
• Special rubber compound: Lowers rolling resistance to reduce fuel consumption and heat build-up when towing moderate loads.
• Trailer-specific design: Built for towable utility, boat, horse and cargo trailers where occasional or shorter-distance hauling is common.
• Clear load capacity: Rated to carry up to 1,820 pounds, making it straightforward to match with trailer load requirements.
• Tire only: Sold without a rim, so buyers must plan to reuse or purchase a compatible wheel separately.

Who It's For

This tire is well suited to owners of small to medium boat trailers, utility trailers, and cargo trailers who make shorter trips or haul infrequently and who need a tire that resists sidewall damage and limits heat build-up. It also fits trailers from many popular manufacturers, making replacement straightforward for common trailer models.

It is not the top choice for heavy, long-distance towing or drivers who require the longest possible tread life in continuous highway service; those users should consider heavier-duty or dedicated radial trailer tires and verify compatibility against their trailer owners manual and sidewall markings.

Pros & Cons

Pros

• Durable sidewall construction protects wheels and holds up well during loading and basic trailering.
• Designed tread and compound reduce rolling resistance and heat for improved efficiency and longevity under moderate use.
• Good compatibility with many boat and utility trailer brands makes replacement fitment straightforward.
• Clear 1,820 lb max capacity and 50 PSI recommendation make load planning simple.

Cons

• Sold as a tire only, so a wheel must be sourced separately which some customers noted as an inconvenience.
• Some users report mixed long-term durability, so heavy frequent use may show faster wear than expected.
