Tire Size 33×12.5r16 in Metric
Have you ever found yourself musing over the seemingly incomprehensible series of numbers and characters stamped on your automobile’s tires, like the 33×12.5r16 tire size? Though it appears to be an obscure code, decoding it is quite straightforward.
- 33: This number represents the overall diameter of the tire in inches. In this case, it’s 33 inches.
- 12.5: This is the tire width, also in inches. So, the tire is 12.5 inches wide.
- R: This letter indicates that the tire has radial construction, the most common type today.
- 16: Lastly, this number represents the wheel diameter in inches. The tire is designed to fit a 16-inch wheel.

|Tire Section Width||12.5″|
|Rim Width Range||16″|
To convert the 33×12.5r16 tire size to metric, we need to focus on the overall diameter, tire width, and wheel diameter.
- To convert 33 inches to millimeters, multiply by 25.4 (1 inch = 25.4mm). This gives us an overall diameter of 838.2mm.
- Similarly, convert the 12.5-inch tire width to millimeters: 12.5 x 25.4 = 317.5mm.
- Convert the 16-inch wheel diameter to millimeters: 16 x 25.4 = 406.4mm.
- Calculate the sidewall height by subtracting the wheel diameter from the overall diameter and dividing the result by 2: (838.2 – 406.4) / 2 = 215.9mm.
- Find the aspect ratio by dividing the sidewall height by the tire width and multiplying the result by 100: (215.9 / 317.5) x 100 = 68%.
33×12.5r16 in Metric
The tire size denoted as 33×12.5r16 can be approximately converted to metric system notation as 318/68r16. However, it’s important to mention that this particular size is uncommonly available in retail stores.
Although there isn’t an exact metric equivalent for the 33×12.5r16 size, the closest widely used metric size would be 315/80r16. This tire has a width of 315mm, an aspect ratio of 80%, and a wheel diameter of 16 inches, which closely resembles our original tire.
The 33×12.5r16 size is popular in the world of off-road vehicles due to its balance of height and width, providing a blend of stability and ground clearance.
For instance, this size is commonly used in off-roading Jeeps or trucks, where the large diameter helps traverse obstacles like rocks and logs. Its width also contributes to better traction on uneven surfaces.
