Tire Size 35×12.50r17 in Metric
Have you ever looked at the side of your car tire and wondered what those cryptic numbers and letters mean? Let’s break down the meaning of a specific tire size, 35×12.50r17, to make it easier to comprehend.
Dimension Breakdown
The figure 35×12.50r17 may seem complicated at first, but it’s just a concise way of expressing three key dimensions of the tire: overall diameter, width, and wheel diameter.
- “35” signifies the overall diameter of the tire, from tread to tread, in inches.
- “12.50” denotes the tire’s width, also in inches, which is the breadth of the tire from one sidewall to the other.
- “R” stands for Radial construction, the most common type in modern tires, where the internal layers run radially from the center of the tire.
- “17” indicates the wheel diameter, the size of the wheel the tire is meant to fit on, measured in inches.
35×12.50r17 in inches
| Feature | Metric |
|---|---|
| Tire Diameter | 35.0″ |
| Tire Section Width | 12.5″ |
| Rim Width Range | 17″ x 8.5-11″ |
| Sidewall Height | 9.0″ |
| Circumference | 109.9″ |
| Revs/Mile | 577 |
Conversion Process
Converting tire dimensions from inches to millimeters is straightforward if you know that 1 inch equals 25.4 millimeters.
Overall Diameter
The “35” in our example signifies the tire’s overall diameter in inches. To convert this to millimeters, multiply 35 by 25.4, giving you an overall diameter of 889 millimeters.
Tire Width
Similarly, the “12.50” in the tire size represents the tire’s width in inches. Multiplying this by 25.4 gives us a tire width of 317.5 millimeters.
Wheel Diameter
“17” is the wheel diameter in inches, which converts to 431.8 millimeters in metric units.
Sidewall Height and Aspect Ratio
To calculate the sidewall height, subtract the wheel diameter from the overall diameter and divide the result by 2. In this case, the sidewall height is (35 – 17) / 2 = 9 inches. Converting to millimeters gives us 228.6 millimeters.
The aspect ratio is the ratio of the tire’s sidewall height to its width, expressed as a percentage. Therefore, the aspect ratio for our tire is (9 / 12.5) * 100% = 72%.
Finding a Close Metric Equivalent
Finding an equivalent metric tire size for 35×12.50r17 involves identifying a tire with a similar overall diameter, width, and aspect ratio. In this case, a 315/70R17 tire would be a close match. The tire’s width (315mm) is close to 317.5mm, and the aspect ratio of 70% is just a bit off our calculated 72%.
Practical Applications
The 35×12.50r17 tire size is popular among pickup trucks and SUVs, like the Ford F-150 or Jeep Wrangler, due to its excellent balance between off-road performance and on-road comfort.
Its large overall diameter and width provide more excellent surface area contact with the ground, improving traction. At the same time, the significant sidewall height helps absorb road shocks, making it perfect for off-road terrains.
What Is Equivalent To A 35×12.50r17?
The tire size 35×12.50r17 can be approximately converted to 318/72R17 in the metric system. However, it’s important to note that this particular tire size is not commonly found in the market.
A more commonly encountered metric size that closely matches the specifications of a 35×12.50r17 tire is 315/70r17. This alternative size offers a comparable option and is readily available for purchase.
How Tall Are 35×12.50r17 Tires?
The tire size of 35×12.50r17 indicates the overall dimensions of the tire. The “35” in size represents the tire’s height, usually measured in inches. Therefore, a 35×12.50r17 tire would have a height of approximately 35 inches.
How Wide Is A 35×12.50r17 Tire?
The second part of the tire size, “12.50,” denotes the tire’s width, also measured in inches. Thus, a 35×12.50r17 tire would have a width of approximately 12.50 inches.
What Size Rim Fits 35×12.50r17?
The last part of the tire size, “17,” indicates the diameter of the wheel rim that the tire is designed to fit. Therefore, a 35×12.50r17 tire requires a rim with a diameter of 17 inches.
Summary
Understanding tire sizes and their metric equivalents is essential for selecting the right tires for your vehicle. In our example, 35×12.50r17 corresponds to a tire with an overall diameter of 35 inches, a width of 12.50 inches, and a wheel diameter of 17 inches.
The metric equivalent for this size is close to 315/70R17. Knowing how to decipher and convert these measurements enables you to make informed tire purchases and empowers you to maximize your vehicle’s performance and safety.
