Prometer ST Radial ST225/75R15 E Trailer Tire

Description

Radial Construction: Unlike bias-ply tires, the radial construction provides a more flexible sidewall and a stiffer tread, leading to better heat dissipation, which is crucial for trailer tires, especially on longer hauls. This also contributes to a smoother ride and more even wear. ST (Special Trailer) Designation: This indicates the tire is specifically designed for trailer applications. ST tires have stiffer sidewalls and different internal construction to handle the unique stresses of trailers, such as constant load carrying and scrubbing during turns, compared to passenger vehicle tires. High Load Range (Load Range C): A Load Range C rating signifies the tire’s ability to carry a substantial amount of weight. For an ST175/80R13, this typically means a higher ply rating and reinforced construction to support the heavy loads common for utility, boat, or cargo trailers. Durable Tread Compound: The tire uses a specialized rubber compound formulated for trailer applications. This compound is designed to resist heat buildup and provide extended tread life, crucial for tires that primarily experience straight-line towing rather than steering forces. Enhanced Stability and Tracking: The combination of radial construction and a robust design for trailer specific uses helps the tire maintain better contact with the road, reducing sway and improving the overall stability and tracking of the trailer, which is vital for safe towing.
