What Size Tire Is 265/60R18 In Inches?
Here are the approximate measurements in inches for a tire size of 265/60R18:
- Diameter of the tire: Approximately 30.5 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: 18 inches
The tire size 265/60R18 can be converted to inches as follows:
- The first number, 265, represents the tire’s width in millimeters.
- The second number, 60, represents the aspect ratio, which is the height of the sidewall as a percentage of the width.
- The letter R indicates that this is a radial tire.
- The last number, 18, represents the diameter of the wheel in inches.
To convert the width from millimeters to inches, we can divide it by 25.4 (since there are 25.4 millimeters in an inch):
- 265 mm ÷ 25.4 = 10.43 inches (rounded to two decimal places)
To calculate the height of the sidewall, we need to multiply the width by the aspect ratio:
- 10.43 inches × 0.60 = 6.26 inches (rounded to two decimal places)
Finally, we can calculate the total diameter of the tire by adding twice the sidewall height to the wheel diameter:
- 2 × 6.26 inches + 18 inches = 30.5 inches (rounded to one decimal place)
Therefore, a tire size of 265/60R18 has a diameter of approximately 30.5 inches.
