Carlisle Sport Trail LH ST175/80D13 91N LRC tire

The Carlisle Sport Trail LH is a highway terrain, all-season tire built for special trailer service. It features a 13-inch rim diameter and a 24-inch overall diameter with a 175/80D13 size designation. The tire carries a load index of 91 and load range C with a 6-ply rating for heavy load capacity.

Bias ply construction and silica compound

The bias ply construction uses a reinforced internal structure and special silica compound to maintain ideal tire shape under heavy loads. This design improves load and driving durability while the optimized tread pattern enhances year-round performance in dry, wet, and winter conditions.

Trailers needing highway stability

This tire suits trailer owners who prioritize towing stability, controllability, and extended tread life on highways. It is not for light truck fitment and buyers needing a rim included with the purchase should look elsewhere.

Questions about this item

How often should the ST175/80D13 tire be inspected for wear or damage?

Check the tire before each trip for cuts, cracks, bulges or uneven tread wear. Rotate and rebalance according to the trailer manufacturer's schedule, and replace the tire once the tread depth reaches the legal minimum or if any sidewall damage appears.

What limits the tire's load capacity during sustained highway use?

The Load Range C (6-ply) construction with a 91 load index sets the maximum load per tire. Exceeding that weight or running above the N speed rating of 87 mph will cause heat buildup and can lead to premature failure.

How much heat does the tire generate on long hauls?

The bias-ply design and silica compound are engineered to dissipate heat at highway speeds up to 87 mph while carrying the rated load. Proper inflation for the 13-inch rim and the 175 mm section width keeps temperatures within safe limits during extended towing.
