What are the dimensions of a 235/70R15 tire in inches?
The numbers in a tire’s size notation refer to its width, aspect ratio, and wheel diameter. In the case of a 235/70R15 tire, the width is 235 millimeters, the aspect ratio is 70%, and the wheel diameter is 15 inches.
To convert these measurements to inches, we can use the following formulas:
- Width (mm to in): 235 mm ÷ 25.4 = 9.29 in (approx.)
- Sidewall height (aspect ratio): 9.25 x 0.70 = 6.48 in (approx.)
- Diameter (2 x sidewall height + wheel diameter): (2 x 6.47 in) + 15 in = 28 in (approx.)
So, a 235/70R15 tire has an approximate diameter of 28 inches.
|Tire Height (Diameter)||28 in||710 mm|
|Wheel Size||15 in||381 mm|
|Sidewall Height||6.5 in||165 mm|
|Tire Width||9.3 in||235 mm|
|Tire Circumference||87.8 in||2,231 mm|
|Revolutions per Mile||721.5|
|Revolutions per Kilometer||448.3|
