295/70R17 Tire Size in Inches & Millimeters

Tire size “295/70R17” indicates your vehicle’s specifications based on tire width, aspect ratio, height, tire construction, diameter, radial and inches. These tire size numbers represent our tire sizes in both Metric (in millimeters) and Imperial (in inches) units of measurement to help find the correct tire size for your vehicle.

To convert tire size 295/70R17 to inches, you must know what these numbers represent.

So let us know 295/70R17 in simple words:

First number “295” indicates the tire’s width in millimeters.
Second number “70” refers to the aspect ratio, which is the height of the tire’s sidewall as a percentage of its width.
Third number “R17” refers to a tire that is designed to fit a 17-inch diameter rim.

Therefore, when converting the tire size 295/70R17 to inches, it can be concluded that the width of the tire will be approximately 11.6 inches ( 295 mm= 11.6 in), and the sidewall height will be approximately 8.1 inches (70% of 11.6 inches = 8.1 inches).

How to convert 295/70R17 into Inches (imperial)?

To convert tire size 295/70R17 to inches (Imperial) –

1. Width conversion: To convert it to inches, you can use a conversion factor of approximately 25.4 millimeters per inch.

  • 295 millimeters/25.4 = approximately 11.6 inches
    So, the width of the tire is approximately 11.6 inches.

2. Aspect Ratio Calculation: To calculate sidewall height in inches, you can use the tire width (from Step 1) and the aspect ratio:

  • Sidewall Height = Width (in inches) * Aspect Ratio / 100
  • Sidewall Height = 11.6 inches * 70/100 = approximately 8.1 inches
    So, the tire sidewall height is approximately 8.1 inches.

3. Rim Diameter: The “R” in the tire size stands for “radial construction” and the last number “17” indicates the rim diameter in inches. In this case, it’s already in inches.
So, the converted tire size “295/70R17” in inches (imperial) is approximately:

  • Width: 11.6 inches
  • Sidewall Height: 8.1 inches
  • Rim Diameter: 17 inches

How to convert 295/70R17 into Millimeters (metric)?

To convert the tire size 295/70R17 into millimeters (metric) –

1. Width Conversion: The first number in the tire size, “295“, represents the tire’s width in millimeters. Since it’s already in millimeters, there’s no need for conversion.

  • Width: 295millimeters

2. Aspect Ratio Calculation: The second number “70” is the aspect ratio, representing the tire’s sidewall height as a percentage of its width. To calculate the sidewall height in millimeters, you can use the tire’s width (from step 1) and the aspect ratio:

  • Sidewall height = Width (in millimeters) * Aspect Ratio / 100
  • Sidewall height = 295 millimeters * 70 / 100 = 207 mm millimeters
    So, the tire’s sidewall height is approximately 207 mm millimeters.

3. Rim Diameter: The “R” in the tire size stands for “radial construction” and the last number, “17” indicates the rim diameter in inches. To convert this to millimeters, you can use the conversion factor of approximately 25.4 millimeters per inch.

  • Rim diameter = 17 inches * 25.4 millimeters per inch = 432 mm millimeters
    So, the rim diameter is approximately 432 mm millimeters.

So, the converted tire size “295/70R17” in millimeters (metric) is approximately:

  • Width: 295 mm
  • Sidewall Height: 207 mm
  • Rim Diameter: 432 mm
