What Size Tire Is 215/60r15 In Inches?
- Diameter of the tire: Approximately 25.16 inches or 639.66 mm
- Tire width: Approximately 8.46 inches
- Sidewall height: Approximately 5.08 inches (calculated as a percentage of the tire’s width, which is 60% in this case)
- Diameter of the wheel: 15 inches
Detailed Explanation:
The tire size 215/60R15 refers to a tire with a width of 215 millimeters, an aspect ratio (or sidewall height as a percentage of the width) of 60%, and a diameter of 15 inches.
Diameter Of The Tire:
To calculate the diameter of the tire, we can use the following formula:
- Diameter = (2 x sidewall height x aspect ratio/100) + wheel diameter (in inches)
First, we need to calculate the sidewall height:
- Sidewall height = width x aspect ratio / 100
- Sidewall height = 215 x 60 / 100 = 129 mm
We can then convert the sidewall height to inches:
- Sidewall height = 129 mm / 25.4 = 5.08 inches (rounded to the nearest hundredth)
Now we can calculate the diameter of the tire:
- Diameter = (2 x sidewall height x aspect ratio/100) + wheel diameter (in inches)
- Diameter = (2 x 5.08 x 60/100) + 15
- Diameter = 25.16 inches (rounded to the nearest hundredth)
Tire Width:
To calculate the tire width in inches, we can use the following formula:
- Tire width = width in millimeters x 0.03937 inches/millimeter
- Tire width = 215 x 0.03937 = 8.46 inches (rounded to the nearest hundredth)
Sidewall Height:
- As we calculated earlier, the sidewall height is 5.08 inches.
Diameter Of The Wheel:
- The diameter of the wheel is 15 inches.
Therefore, the 215/60R15 tire has an overall diameter of approximately 25.16 inches, a tire width of approximately 8.46 inches, a sidewall height of approximately 5.08 inches, and a wheel diameter of 15 inches.
Tire Height (Diameter) | 25.2 in | 639 mm |

Revolutions per Kilometer | 498.1 |
What Does It Mean By 215/60R15?
The tire size 215/60R15 is a standardized code that describes the tire’s size, construction, and other important specifications.
Here’s what each of the numbers and letters in the code means:
- 215: The first number in the code (215) represents the tire’s width in millimeters from sidewall to sidewall when it’s mounted and inflated to the recommended pressure.
- 60: The second number in the code (60) is the aspect ratio or profile of the tire, which is the ratio of the height of the tire’s sidewall to its width. In this case, the height of the sidewall is 60% of the tire’s width.
- R: The “R” in the code stands for “radial,” which indicates the tire’s construction type. Most modern tires are radial, meaning that the tire’s plies (layers of fabric or rubber that provide strength) run perpendicular to the direction of travel.
- 15: The last number in the code (15) represents the diameter of the wheel in inches that the tire is designed to fit.
So, a tire with the size 215/60R15 has a width of 215 millimeters, a sidewall height of 60% of its width, a radial construction type, and is designed to fit a 15-inch wheel.
