37×13.5r22 in Metric
Choosing the right tire size for your vehicle can be challenging, especially when navigating between imperial and metric measurements.
The tire size 37×13.5R22 is a favorite among off-road enthusiasts for its robust profile, but converting it to a metric equivalent can be confusing.
The closest metric equivalent for the 37×13.5R22 tire is 325/55R22. We’ll break down the conversion process, explore the details of this metric size, and explain why it matters when considering a tire switch.
Understanding Tire Size
The imperial tire size 37×13.5R22 breaks down into four components, each conveying critical information:
- Overall Diameter: The first number (37 inches) refers to the overall diameter of the tire. This measurement shows how tall the tire is from top to bottom when inflated.
- Tire Width: The second number (13.5 inches) represents the tire’s width, measured from sidewall to sidewall.
- Construction Type: The letter “R” stands for Radial construction, the most common type of construction for tires today.
- Rim Diameter: The final number (22 inches) indicates the diameter of the wheel or rim that the tire fits.
So, a 37×13.5R22 tire has an overall diameter of 37 inches, is 13.5 inches wide, and is designed for a 22-inch rim.
This format, typical of imperial tire measurements, is straightforward for those familiar with it, but might be less so for those used to the metric system.
Closest Metric Equivalent
To find the closest metric equivalent to a tire size like 37×13.5R22, we need to look at the measurements and convert them step by step.
The closest metric equivalent is 345/50R24, which matches very closely in terms of dimensions and performance.
- Width Conversion: The width of 13.5 inches translates to approximately 343 mm, rounded to 345 mm for metric sizing.
- Overall Diameter: The overall diameter of a 37-inch tire is about 939 mm. The 345/50R24 tire has an overall diameter of roughly 933 mm, making it a close match in size.
- Aspect Ratio and Rim Size: The aspect ratio (50) and rim diameter (24 inches) are chosen to keep the overall dimensions similar to the original tire. This ensures that the tire will perform similarly, maintaining speedometer accuracy, vehicle stability, and clearance without any major modifications.
The similarities between these two sizes ensure that the vehicle’s handling remains consistent, providing similar ride comfort and aesthetics.
