What Size Tire Is 305/50r15 In Inches?
- Diameter of the tire: Approximately 27 inches or 686mm
- Tire width: Approximately 12 inches
- Sidewall height: Approximately 5.5 inches (calculated as a percentage of the tire’s width, which is 50% in this case)
- Diameter of the wheel: 15 inches
Detailed Explanation:
Here’s a detailed explanation for tire size 305/50R15 in inches:
The tire size 305/50R15 refers to a tire with a width of 305 millimeters, an aspect ratio (or sidewall height as a percentage of the width) of 50%, and a diameter of 15 inches.
Diameter Of The Tire:
To calculate the diameter of the tire, we can use the following formula:
Diameter = (2 x sidewall height x aspect ratio/100) + wheel diameter (in inches)
First, we need to calculate the sidewall height:
- Sidewall height = width x aspect ratio / 100
- Sidewall height = 305 x 50 / 100 = 152.5 mm
We can then convert the sidewall height to inches:
- Sidewall height = 152.5 mm / 25.4 = 6 inches (rounded to the nearest hundredth)
Now we can calculate the diameter of the tire:
- Diameter = (2 x sidewall height x aspect ratio/100) + wheel diameter (in inches)
- Diameter = (2 x 6 x 50/100) + 15
- Diameter = 27 inches (rounded to the nearest hundredth)
Tire Width:
- To calculate the tire width in inches, we can use the following formula:
- Tire width = width in millimeters x 0.03937 inches/millimeter
- Tire width = 305 x 0.03937 = 12 inches (rounded to the nearest hundredth)
Sidewall Height:
- As we calculated earlier, the sidewall height is 6 inches.
Diameter Of The Wheel:
- The diameter of the wheel is 15 inches.
Therefore, the 305/50R15 tire has an overall diameter of approximately 27 inches, a tire width of approximately 12 inches, a sidewall height of approximately 6 inches, and a wheel diameter of 15 inches. It’s important to note that these are approximate measurements, and actual tire sizes can vary slightly depending on the brand and model of the tire.

Wheel Size | 15 in | 381 mm |
Sidewall Height | 6 in | 153 mm |
Tire Width | 12 in | 305 mm |
Tire Circumference | 84.8 in | 2,155 mm |
Revolutions per Mile | 746.8 | |
Revolutions per Kilometer | 464 |
What Does It Mean By 305/50R15?
305/50R15 is a tire size specification used to describe the physical characteristics of a tire. Here’s what each number and letter in the specification means:
- 305: This number represents the width of the tire in millimeters. In this case, the tire is 305 millimeters wide.
- 50: This number represents the aspect ratio of the tire, which is the ratio of the sidewall’s height to the tire’s width. The sidewall height is 50% of the tire width in this case.
- R: This letter represents the construction of the tire. “R” stands for radial construction, the most common type of tire construction today.
- 15: This number represents the diameter of the wheel in inches that the tire is designed to fit.
