Have you ever looked at the side of your tires in Providence and felt confused by the numbers and letters there? If you have, you’re not alone. Many people wonder, “What Do The Numbers On Tires Mean?” Don’t worry, these codes aren’t mysterious. Instead, they form a language that reveals important details about your tire’s size, type, and abilities. Whether you’re shopping for new tires or just curious, let the automotive experts at Mercedes-Benz of Warwick in Warwick help you understand what these tire numbers mean.

Determining Tire Number Meanings

Let’s break down the alphanumeric sequence systematically to get a clear understanding of tire numbers. This breakdown will answer the question, “What do the numbers on tires mean?”

Example: P215/65R15 95H Tire Number Meaning

Though it may appear perplexing, each segment of the code serves as a key to identifying the tire accurately. Let’s dive into the tire number meaning using the example P215/65R15 95H.

Decoding “P”

The initial letter, such as “P,” is pivotal in categorizing the tire. “P” designates a “P-Metric tire,” suitable for passenger vehicles. “LT” signifies “light truck” tires, ideal for lightweight pickups. The absence of a letter indicates a Euro-Metric tire with distinct load capacities.

Decoding “215”

Numeric values like “215” denote the tire’s width in millimeters, measured from one sidewall to the other. In our example, the tire spans 215 millimeters in width.

Decoding “65”

Following the slash, a number like “65” signifies the aspect ratio. This figure represents the tire’s cross-sectional height as a percentage of its width. A 65% ratio implies that the height is 65% of the width, resulting in taller sidewalls for higher ratios.

Decoding “R”

The “R” denotes the tire’s construction, specifically indicating that it is a radial.

Decoding “15”

“15” specifies the wheel size by revealing the wheel’s diameter in inches. In this case, the tire is suitable for a 15-inch wheel.

Decoding “95H”

The last number, “95H,” reveals the load index and speed rating. “95” is the load index, telling you the most weight the tire can handle when properly inflated. For passenger vehicles, this index typically ranges from 75 to 105. The letter “H” stands for the speed rating, indicating the tire’s safe maximum speed according to its load capacity. Different letters mean different speed limits; in this case, “H” allows speeds up to 130 mph.
