What Size Tire Is 265/60R20 In Inches?
The tire size 265/60R20 refers to a tire with a width of 265 millimeters, an aspect ratio (or sidewall height as a percentage of the width) of 60%, and a diameter of 20 inches.
Here are the approximate measurements in inches:
- Diameter of the tire: Approximately 32.5 inches
- Tire width: Approximately 10.4 inches
- Sidewall height: Approximately 6.3 inches (calculated as a percentage of the tire’s width, which is 60% in this case)
- Diameter of the wheel: 20 inches
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 = 265 x 60 / 100 = 159 mm
We can then convert the sidewall height to inches:
- Sidewall height = 159 mm / 25.4 = 6.3 inches
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 6.2 x 60/100) + 20
- Diameter = 32.5 inches (approximately)
Therefore, the 265/60R20 tire has an overall diameter of approximately 32.5 inches, a tire width of approximately 10.4 inches, a sidewall height of approximately 6.2 inches, and a wheel diameter of 20 inches. Please note that these are approximate measurements, and actual tire sizes can vary slightly depending on the brand and model of the tire.
