Detailed Explanation
Here’s a detailed explanation of tire size 175/50R15 in inches:
The tire size 175/50R15 refers to a tire with a width of 175 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 = 175 x 50 / 100 = 87.5 mm
We can then convert the sidewall height to inches:
- Sidewall height = 87.5 mm / 25.4 = 3.44 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 3.44 x 50/100) + 15
- Diameter = 21.91 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 = 175 x 0.03937 = 6.89 inches (rounded to the nearest hundredth)
Sidewall Height:
As we calculated earlier, the sidewall height is 3.44 inches.
Diameter Of The Wheel:
- The diameter of the wheel is 15 inches.
Therefore, the 175/50R15 tire has an overall diameter of approximately 21.91 inches, a tire width of approximately 6.89 inches, a sidewall height of approximately 3.44 inches, and a wheel diameter of 15 inches. Please note that these are approximate measurements, and actual tire sizes can vary slightly depending on the brand and model of the tire.
Tire Height (Diameter) | 21.9 in | 556 mm |

Sidewall Height | 3.4 in | 88 mm |
Tire Width | 6.9 in | 175 mm |
Tire Circumference | 68.8 in | 1,747 mm |
Revolutions per Mile | 921.4 | |
Revolutions per Kilometer | 572.5 |
What Does It Mean By 175/50R15?
The tire size 175/50R15 refers to a tire with a width of 175 millimeters, an aspect ratio (or sidewall height as a percentage of the width) of 50%, and a diameter of 15 inches. The “R” in size indicates that it has a radial construction.
- The first number (175) represents the tire width in millimeters.
- The second number (50) represents the aspect ratio, which is the height of the sidewall as a percentage of the tire’s width.
- The “R” indicates that the tire has radial construction.
- The last number (15) represents the diameter of the wheel in inches, which the tire is designed to fit.
In summary, the 175/50R15 tire has a width of 175 millimeters, a sidewall height of 50% of the width, a radial construction, and is designed to fit a 15-inch wheel.
Frequently Asked Question
What Is The Maximum Load Capacity Of A 175/50r15 Tire?
The maximum load capacity of a tire depends on its load index. For a 175/50R15 tire, the load index is typically around 75, which translates to a maximum load capacity of 852 pounds per tire.
Can A 175/50r15 Tire Fit On Any 15-Inch Wheel?
No, a 175/50R15 tire can only fit on a 15-inch wheel with a width between 4.5 and 6.0 inches.
What Is The Speed Rating Of A 175/50r15 Tire?
The speed rating of a tire indicates the maximum speed at which it can safely operate. For a 175/50R15 tire, the speed rating is typically around H, which means it can safely operate at speeds up to 130 mph.
Can A 175/50r15 Tire Be Used In Snowy Or Icy Conditions?
It depends on the tire’s tread pattern and composition. Some 175/50R15 tires are designed for snowy or icy conditions, while others are not. It’s essential to check the tire’s specifications before using it in such conditions.
What Is The Aspect Ratio Of A 175/50r15 Tire?
A tire’s aspect ratio is the ratio of the tire’s sidewall height to its width. For a 175/50R15 tire, the aspect ratio is 50%, which means the sidewall height is 50% of the tire’s width.
How Can I Measure The Tread Depth Of A 175/50r15 Tire?
You can use a tread depth gauge to measure a tire’s tread depth. Insert the gauge into the tire’s grooves and measure the depth. The minimum legal tread depth is 2/32 inches, but replacing tires at 4/32 inches is recommended.
Can A 175/50r15 Tire Be Used On A Car With A Different Tire Size?
It’s not recommended to use a tire size significantly different from a car’s recommended size. Using a tire size that is too small or too large can affect the car’s handling, stability, and safety.
What Is The Rolling Circumference Of A 175/50r15 Tire?
The rolling circumference of a tire is the distance it travels in one revolution. A 175/50R15 tire’s rolling circumference is approximately 67.8 inches.
