Tire Size Conundrum: What Size Tires Are 315?
As we delve into the world of tire sizes, a common misconception arises: “What size tires are 315?” Many believe that 315 refers to the diameter of the tire. However, the truth lies in a more nuanced understanding of tire sizing. Let’s break it down.
A Brief History of Tire Sizing
In the early days of tire manufacturing, tire sizes were primarily indicated by a combination of letter and number codes. This system, known as the “letter-number” system, often left consumers confused. For example, a tire size like “B78-14” might seem arbitrary. However, this code actually reveals valuable information about the tire’s dimensions. The letter “B” indicates the tire’s load range, while the “78” represents the tire’s section width, and the “14” denotes the wheel diameter in inches.
The Modern Tire Sizing System
Fast forward to the modern era, and the tire sizing system has evolved. The Society of Automotive Engineers (SAE) introduced the “metric” or “european” tire sizing system, which uses a combination of letters and numbers to describe tire size. In this system, tire sizes are indicated by a series of codes, such as “235/60R17” or “315/70R17”. But what do these codes mean?
Deciphering the Code
Let’s break down the code “315/70R17”:
“70” represents the tire’s aspect ratio, which is the ratio of the tire’s section height to its section width.
“17” represents the wheel diameter in inches.
So, what size tires are 315? If we look at the section width code, “315” indeed refers to the tire’s section width in millimeters. In this case, a 315 tire has a section width of 315 millimeters.
Aspect Ratio: The Hidden Factor
When comparing tire sizes, it’s essential to consider the aspect ratio, which affects the tire’s overall diameter. A higher aspect ratio (e.g., 70) results in a taller tire, while a lower aspect ratio (e.g., 50) results in a shorter tire.
To illustrate this, let’s compare two tire sizes with the same section width (315mm):
315/70R17: This tire has an aspect ratio of 70, resulting in a diameter of approximately 30.4 inches.
As you can see, the aspect ratio significantly impacts the tire’s overall diameter. This is why it’s crucial to consider both the section width and aspect ratio when comparing tire sizes.
