This listing is for new Carlisle Sport Trail LH ST185/80D13 D/8PLY Tires. Manufacturer part number: 6H02231.

The Carlisle Sport Trail LH is a specialty trailer tire designed to deliver stable towing, long lasting durability, and dependable performance for a wide range of trailers. It uses a heat resistant rubber compound that helps control temperature buildup during long hauls and heavy load conditions. This formulation supports better tread life and consistent reliability, making the Sport Trail LH a strong choice for frequent towing and extended highway travel.

The tread pattern features a smooth, symmetric rib design that enhances straight line tracking and reduces trailer sway. This layout improves stability at higher speeds and helps the trailer follow the tow vehicle more predictably. The rounded shoulder profile supports even tread wear while maintaining steady contact with the road. Carlisle engineered the footprint to distribute weight efficiently, improving load support and helping the tire resist irregular wear.

Built with a reinforced internal structure, the Sport Trail LH offers strong sidewall durability and excellent load carrying capability. Its construction is designed specifically for trailer applications, supporting controlled handling during turns, backing maneuvers, and heavy duty usage.

Best Suited For

The Carlisle Sport Trail LH is ideal for boat trailers, utility trailers, travel trailers, cargo haulers, and recreational equipment trailers that require stable towing, dependable load support, and long term durability. It is a strong match for drivers who tow frequently and want a trailer tire built for consistent performance on highways and secondary roads.

Description

Sidewall

Not Available

Describes the sidewall appearance. Examples: BSW= Black Side Wall, WSW = White Side Wall, OWL = Outlined White Letters.

Load Index

Not Available

The load index (LI) is a 2- or 3-digit number that correlates to the maximum amount of weight the tire can carry. For example, a tire with a load index of 87 indicates that the tire can carry a maximum load of 1,201 lbs. In this particularly example, 4 tires (each with a load index of 87) can carry a maximum of 4,804 lbs. Refer to your vehicle owner's manual for the recommended minimum load index.

Speed Rating
Tires speed rating

Not Available

Speed rating (SR) indicates the maximum speed the tire can achieve. Higher speed ratings are typically associated with better handling capabilities. Refer to your vehicle owner's manual for the recommended minimum speed rating.

Load Range/Ply Rating

D/8PLY

Ply rating, more commonly referred to as load range, represents the strength and durability of the tire. Higher ratings may indicate your tires can handle heavier loads.

UTQG

Not Available

To help consumers evaluate their tires, the U.S. National Highway Traffic Safety Administration (NHTSA) created the Uniform Tire Quality Grading System (UTQG). The UTQG rates tires are rated on their tread-wear, traction performance, and temperature resistance. The grade for each of these can be found on the sidewall of your tire (except for winter tires and certain light truck tires).

Max Single Load(lbs)

1710

The maximum load this tire will support. Remember to multiply this number by the number of tires installed on your vehicle to get the maximum carrying capacity. This number is directly related to the Load Index.

Max Single Air Pressure(PSI)

The maximum air pressure this tire will support. This does not represent the amount of air pressure your tires should have at all times. Consult with your owner's manual to determine the best air pressure you should use for your vehicle.

Tread Depth

8.0

The amount of tread on the tire. Once the tire is worn to 2/32nds, it is considered fully used and should be replaced at that time. Most tires will have tire indicators in the grooves of the tire to help you determine when the tires are worn down to 2/32nds.

Tread Design

Nondirectional

The pattern of the grooves, lugs, voids, and sipes on a tire's surface. This design affects the tire's traction, handling, and noise characteristics. Common types include symmetrical (uniform pattern across the tire), asymmetrical (different patterns on the inside and outside for varied road conditions), and directional (designed to rotate in one direction for improved wet traction and hydroplaning resistance).

Rim Width Range

5.0-0.0

The approved wheel rim width range this tire will support.

Measured Rim Width

4.5

The recommended wheel width as recommended by the tire manufacturer to get the best wear us performance for this tire.

Section Width

7.1

The measurement from sidewall to sidewall.

Tread Width

Not Available

The measurement from one side of the tread to the other side of the tread.

Overall Diameter

24.4

The height of the tire when fully inflated.
