- Sidewall height: Approximately 2.6 inches (calculated as a percentage of the tire’s width, which is 40% in this case)
- Diameter of the wheel: 16 inches
Detailed Explanation:
Here is a detailed explanation for the tire size 165/40R16 in inches:
The tire size 165/40R16 refers to a tire with a width of 165 millimeters, an aspect ratio (or sidewall height as a percentage of the width) of 40%, and a diameter of 16 inches.
Diameter Of The Tire:
To calculate the overall diameter of the tire, we can use the following formula:
- Diameter = sidewall height x 2 + wheel diameter
First, we need to calculate the sidewall height:
- Sidewall height = width x aspect ratio / 100
- Sidewall height = 165 x 40 / 100 = 66 mm
Converting the sidewall height to inches:
- Sidewall height = 66 x 0.0393701 = 2.59 inches (rounded to the nearest hundredth)
Now, we can calculate the diameter of the tire:
- Diameter = sidewall height x 2 + wheel diameter
- Diameter = 2.6 x 2 + 16 = 21.2 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 0.0393701 inches/millimeter
- Tire width = 165 x 0.0393701 = 6.50 inches (rounded to the nearest hundredth)
Sidewall:
- As we calculated earlier, the sidewall height is 2.59 inches.
Diameter Of The Wheel:
- The diameter of the wheel is 16 inches.
Therefore, the 165/40R16 tire has an overall diameter of 21.2 inches, a width of 6.50 inches, a sidewall height of 2.6 inches, and a wheel diameter of 16 inches. It’s important to note that these are approximate measurements, and actual tire sizes can vary slightly depending on the brand and model of the tire.
