The ‘ST’ prefix signifies “Particular Trailer,” denoting the tire is designed for trailer purposes, not passenger autos. The ‘225’ specifies the tire’s part width in millimeters, whereas ’75’ represents the facet ratio, the share of the part width that equals the sidewall top. The ‘R’ signifies radial development, and ’15’ signifies the wheel diameter in inches. This entire code identifies a tire optimized for the load and efficiency calls for of towed trailers.
Deciding on the appropriately sized and rated tire is essential for protected and environment friendly towing. These tires are engineered to face up to the upper masses and distinctive stresses related to trailer use, stopping untimely put on, dealing with points, and potential tire failure. Using tires constructed for these situations contributes to improved gasoline economic system, enhanced stability, and total security throughout transit. The engineering included into these tires relies on years of expertise and refined materials science.
