Tire Size 33×12.5r17 in Metric
If you have encountered a tire size like 33×12.5r17, what does it mean, and how does it translate to the metric system? This article will break down each dimension of this tire size, convert it to metric units, and explore its practical applications.
Dimension Breakdown
- 33: The first number represents the overall diameter of the tire in inches. In this case, the tire has an overall diameter of 33 inches.
- 12.5: The second number indicates the tire width, also in inches. This tire is 12.5 inches wide.
- R: The letter ‘R’ stands for radial construction, which is a common design for modern tires.
- 17: The final number is the wheel diameter, measured in inches. This tire is designed to fit a 17-inch wheel.
33×12.5r17 in inches
| Feature | Metric |
|---|---|
| Tire Diameter | 33.0″ |
| Tire Section Width | 12.5″ |
| Rim Width Range | 17″ x 8.5-11″ |
| Sidewall Height | 8.0″ |
| Circumference | 103.6″ |
| Revs/Mile | 611 |
Conversion Process
- To convert the 33-inch overall diameter to millimeters, multiply by 25.4 (1 inch = 25.4 mm). 33 x 25.4 = 838.2 mm.
- Converting the 12.5-inch tire width to millimeters follows the same process. 12.5 x 25.4 = 317.5 mm.
- Likewise, the 17-inch wheel diameter is converted by multiplying by 25.4. 17 x 25.4 = 431.8 mm.
- This can be calculated by subtracting the wheel diameter from the overall diameter and dividing by 2. (33 – 17) / 2 = 8 inches. Then, convert inches to millimeters. 8 x 25.4 = 203.2 mm.
- The aspect ratio is the ratio of the sidewall height to the tire width, expressed as a percentage. (203.2 / 317.5) x 100 = 64%.
33×12.5r17 in Metric
The tire size given as 33×12.5r17 can be approximated in the metric system as 318/64r17, although it’s important to mention that this particular dimension is seldom found in stores.
For a metric counterpart of the 33×12.5r17 tire size, look for a tire that has a comparable overall diameter, width, and aspect ratio, like a 315/65r17. While these dimensions aren’t perfect equivalents, they are sufficiently similar to be considered suitable substitutes.
Practical Applications
The 33×12.5r17 tire size is often found on off-road vehicles, such as Jeeps, pickup trucks, and SUVs. The large diameter and width provide increased ground clearance and traction, making it ideal for navigating rough terrain.
A real-world example is the Jeep Wrangler Rubicon, which can be equipped with 33×12.5r17 tires for enhanced off-road capabilities.
