33×12.50r17 in Metric
Understanding the differences between imperial and metric measurements is crucial. One tire size that often requires a metric equivalent is the 33×12.50R17.
Knowing the closest metric equivalent can save you a lot of guesswork, especially when it comes to ensuring compatibility and performance.
For those using a 33×12.50R17 tire, the closest metric equivalent is typically 315/70R17. In this article, we’ll break down the conversion process, explore the alternatives, and provide expert insights into the best choices.
Understanding Tire Size
Understanding imperial tire size notations can be confusing at first, but it’s quite simple when you break down each component:
- Overall Diameter (33 inches): This number tells us the total height of the tire from the ground to the top.
- Tire Width (12.50 inches): This represents the width of the tire, measured from sidewall to sidewall.
- Construction Type (R): The letter ‘R’ stands for Radial construction, which is the most common type used today.
- Rim Diameter (17 inches): This indicates the size of the wheel (rim) that the tire is designed to fit.
For example, the imperial tire size 33×12.50R17 breaks down as follows: a 33-inch overall diameter, a 12.50-inch width, radial construction, and a 17-inch rim diameter.
Closest Metric Equivalent
The closest metric equivalent to 33×12.50R17 is generally 315/70R17. This equivalency is derived from several factors, including width, aspect ratio, and overall diameter. Let’s take a look at why:
- Width: The width of the 33×12.50R17 tire is 12.50 inches, which is approximately 318 mm. The metric size 315/70R17 closely aligns with this, having a nominal width of 315 mm.
- Aspect Ratio and Overall Diameter: The aspect ratio (the sidewall height as a percentage of the tire width) is calculated in a way that ensures the overall diameter of 315/70R17 matches the 33-inch height of the 33×12.50R17. This close match guarantees that the vehicle’s handling, speedometer accuracy, and ride comfort remain consistent.
The similarity between these two sizes ensures optimal vehicle performance without significant alterations. Switching to a 315/70R17 means you can maintain the same ground clearance, minimize speedometer deviation, and preserve the overall handling characteristics of your vehicle.
Alternatives to This Size
There are other sizes that can also serve as alternatives if you’re looking for a slightly different fit or performance. Below is a table of potential alternatives that have similar overall diameters to 33×12.50R17.
| Tire Size | Overall Diameter | Difference (%) |
|---|---|---|
| 305/65R17 | 32.60 | -1.21% |
| 305/70R17 | 33.81 | 2.45% |
| 315/55R17 | 32.76 | -0.73% |
| 305/30R26 | 33.20 | 0.61% |
| 305/45R22 | 32.83 | -0.52% |
| 305/55R20 | 33.21 | 0.64% |
| 315/45R21 | 33.27 | 0.82% |
| 325/60R18 | 33.35 | 1.06% |
These alternatives provide options depending on your specific needs. For example, if you are looking for a tire with a slightly lower profile, the 305/65R17 may be a good choice.
Alternatively, if you prefer a tire with a little more height, the 305/70R17 offers a larger overall diameter.

How Tall is a 33×12.50R17 Tire?
A 33×12.50R17 tire is 33 inches tall. This measurement represents the overall diameter of the tire, from the ground to the top of the tire when mounted and inflated to the recommended pressure.
How Wide is a 33×12.50R17 Tire?
The width of a 33×12.50R17 tire is 12.50 inches. This width is measured from sidewall to sidewall, providing a stable footprint that is suitable for a variety of driving conditions, including off-road terrain.
What Size Rim Fits a 33×12.50R17?
A 33×12.50R17 tire is designed to fit a 17-inch rim. It is important to use the correct rim size to ensure proper mounting, safety, and performance of the tire.
Our Observation
After careful consideration, the 315/70R17 stands out as the optimal metric equivalent for those looking to replace a 33×12.50R17 tire.
Its near-identical overall diameter ensures that vehicle dynamics remain unchanged, preserving both safety and performance.
Additionally, the slight reduction in width compared to other alternatives minimizes the risk of rubbing against the vehicle’s suspension or bodywork.
While there are other possible alternatives, the 315/70R17 offers the best combination of ride comfort, ground clearance, and speedometer accuracy.
However, before making a switch, it is always recommended to consult with a tire professional to confirm compatibility and ensure that the selected size meets all load and speed rating requirements for your vehicle.
