What Size Tire Is 285/70r17 In Inches?
- Diameter of the tire: Approximately 32.71 inches or 831.14 mm
- Tire width: Approximately 11.22 inches
- Sidewall height: Approximately 7.85 inches (calculated as a percentage of the tire’s width, which is 70% in this case)
- Diameter of the wheel: 17 inches
Detailed Explanation:
First, let’s break down what each part of the tire size notation means:
- 285: This number represents the width of the tire in millimeters. In this case, the tire is 285 millimeters wide.
- 70: This number represents the aspect ratio, which is the ratio of the height of the tire’s sidewall to the width of the tire. In this case, the sidewall height is 70% of the tire’s width.
- R: This letter indicates that the tire has radial construction.
- 17: This number represents the diameter of the wheel in inches.
Using this information, we can calculate the tire’s dimensions in inches:
- Diameter of the tire: To calculate the tire’s diameter, we need to add the height of the sidewall on both sides of the tire to the diameter of the wheel. The height of the sidewall can be calculated by multiplying the tire’s width by the aspect ratio (expressed as a decimal). In this case, the height of the sidewall is 0.7 x 285mm = 199.5mm (or 7.85 inches). So the diameter of the tire is:
Diameter = (2 x sidewall height in inches) + wheel diameter in inches = (2 x 7.85 inches) + 17 inches = 32.71 inches
- Tire width: The tire width is simply the width of the tire in millimeters converted to inches. In this case, the tire width is 285mm / 25.4 = 11.22 inches.
- Sidewall height: As mentioned earlier, the sidewall height can be calculated by multiplying the tire’s width by the aspect ratio (expressed as a decimal). In this case, the sidewall height is 0.7 x 285mm = 199.5mm (or 7.85 inches).
- Diameter of the wheel: The wheel’s diameter is 17 inches, as indicated by the last part of the tire size notation.
In summary, the 285/70R17 inches tire represents a tire that is 11.22 inches wide, has a sidewall height of 7.85 inches, and has an overall diameter of 32.71 inches. These dimensions are important to consider when selecting tires for your vehicle, as they can impact handling, clearance, and other aspects of performance.
