Final answer:
The diameter of a tire with the size P235/60/R14 is closest to 26.96 inches. This is calculated by converting tire width to inches, calculating sidewall height, and adding it to the wheel diameter.
Step-by-step explanation:
To determine the diameter of a tire with the original tire size of P235/60/R14, we need to understand what each part of this size specification means. 'P' stands for passenger vehicle, '235' is the width of the tire in millimeters, '60' is the aspect ratio that expresses the height of the tire sidewall as a percentage of the tire width, and 'R14' means the tire fits on a 14-inch diameter wheel. The diameter of the tire can be calculated as follows:
Convert the width to inches: 235 mm / 25.4 mm/in = 9.25 inches.
Calculate the sidewall height: (60/100) * 9.25 inches = 5.55 inches.
Find the overall diameter: (2 * sidewall height) + wheel diameter = (2 * 5.55 inches) + 14 inches = 26.1 inches.
Therefore, the closest estimated diameter of the tire from the provided options is 26.96 inches (Option 1).
