36×12.50r20 in Metric

36x12.50r20 in MetricUnderstanding how to convert these measurements is crucial to ensure your vehicle performs safely and efficiently.

Today, we’re focusing on the tire size 36×12.50R20, a popular choice among off-road enthusiasts, and determining its closest metric equivalent.

The answer? The closest metric match for a 36×12.50R20 is a 315/60R20. Let’s dive into the details of why this is the best match, what it means, and explore some alternative tire sizes that might fit your vehicle as well.

Reading Tire Size

The tire size 36×12.50R20 might look confusing at first glance, but it’s actually straightforward once you break it down:

  • 36: This is the overall diameter of the tire, measured in inches. It represents the height of the tire from one side to the other.
  • 12.50: This refers to the width of the tire in inches. A wider tire offers better traction, which can be ideal for off-road conditions.
  • R: The letter “R” stands for Radial construction. It means the tire’s internal construction has radial ply cords arranged perpendicular to the direction of travel, providing improved flexibility.
  • 20: This number represents the rim diameter in inches. It tells you the size of the wheel the tire fits on.

For example, the imperial tire size 36×12.50R20 breaks down as a tire that’s 36 inches tall, 12.50 inches wide, with a radial construction, and fits a 20-inch rim.

Closest Metric Equivalent

Finding the closest metric equivalent involves converting the dimensions of the imperial tire to metric. The imperial size 36×12.50R20 translates roughly to the metric size 315/60R20. Here’s why:

  • Width: The imperial width of 12.50 inches converts to approximately 315 mm in metric terms, making 315 a close match.
  • Aspect Ratio: The aspect ratio of a tire represents the height of the sidewall as a percentage of the tire width. In this case, the 315/60R20 aspect ratio means that the sidewall height is 60% of the width, which brings the overall diameter of the tire close to 36 inches.
  • Overall Diameter: The overall diameter of a 315/60R20 is 35.88 inches, which is only slightly smaller than 36 inches (a difference of -0.33%). This slight difference ensures that the new tire size closely matches the original in terms of performance, speedometer accuracy, and ground clearance.

By selecting the 315/60R20, you maintain almost identical handling, tire height, and speedometer calibration compared to the original 36×12.50R20, ensuring optimal performance without the need for any major vehicle modifications.

Alternatives to This Size

While the 315/60R20 is the closest match, there are a few other alternatives that could be suitable based on your specific needs.

Below is a table comparing different tire sizes along with their overall diameters and the percentage difference in diameter compared to the original 36×12.50R20:

Tire Size Overall Diameter Difference (%)
315/60R20 35.88 -0.33%
325/60R20 35.35 -1.81%
35X12.5R20 35.00 -2.78%
35X13R20 35.00 -2.78%
37X12.5R20 37.00 2.78%
305/55R22 35.21 -2.19%
315/70R18 35.36 -1.78%
325/55R22 35.95 -0.14%
315/45R24 36.27 0.75%
36×12.50R20 36.00 0.00%
37×12.50R20 37.00 2.78%

These alternatives are great options if you’re considering minor adjustments to your vehicle’s tire size for a different aesthetic, better performance, or more specialized driving conditions.

For instance, the 325/60R20 could be suitable if you want a slightly wider tire with increased stability, while the 37×12.50R20 provides a taller stance for enhanced ground clearance.
