Tire Size 35×12.5r22 to Metric
Ever pondered about those cryptic numbers and letters on your vehicle’s tires and wondered what they signify? Among such fascinating numbers is the 35×12.5r22, a standard tire size in the trucking industry. But what do these digits tell us, and why do they matter?
Dimension Breakdown
Diving into the world of tire sizes, we must first decode this mystery of alphanumeric characters. The number sequence 35×12.5r22, seemingly complex, is actually a basic expression of the tire’s key dimensions.
Let’s Decode it:
- The initial ’35’ represents the overall diameter of the tire in inches, which is the distance from one edge of the tire to the other.
- ‘12.5’ is the tire width, indicating how broad the tire is across its tread, measured in inches.
- The letter ‘r’ represents radial, denoting the tire’s construction type.
- Lastly, ’22’ indicates the wheel diameter, signifying the size of the wheel that the tire is designed to fit, measured in inches.
35×12.5r22 in inches
| Feature | Metric |
|---|---|
| Tire Diameter | 35.0″ |
| Tire Section Width | 12.5″ |
| Rim Width Range | 22″ x 8.5-11″ |
| Sidewall Height | 6.5″ |
| Circumference | 109.9″ |
| Revs/Mile | 577 |
Conversion Process
Converting these imperial measurements to metric (millimeters) can be a little tricky, but let’s break it down for clarity.
- Overall Diameter: To convert the overall diameter from inches to millimeters, simply multiply the inches by 25.4 (1 inch equals 25.4mm). Therefore, a 35-inch tire would have an overall diameter of 889mm.
- Tire Width: The tire width conversion follows the same principle. For a 12.5-inch wide tire, multiplying by 25.4 gives us a tire width of 317.5mm.
- Wheel Diameter: Converting the 22-inch wheel diameter, we get a metric wheel diameter of 558.8mm.
Sidewall Height & Aspect Ratio
Calculating the sidewall height and aspect ratio requires a bit more arithmetic. According to the given formula, the sidewall height in inches equals (Overall Diameter – Wheel Diameter) / 2. So for a 35×12.5r22 tire, the sidewall height is (35 – 22) / 2, or 6.5 inches.
The aspect ratio, which shows the height of the tire’s sidewall as a percentage of its width, is calculated by (Sidewall Height / Tire Width) * 100%. In our case, this equates to (6.5 / 12.5) * 100%, or an aspect ratio of approximately 52%.
Finding a Close Metric Equivalent
Identifying a close metric equivalent for a 35×12.5r22 tire involves translating these calculated metric values into an equivalent tire size in the metric system.
Tire sizes in the metric system are typically represented as [Tire Width]/[Aspect Ratio]R[Wheel Diameter]. Therefore, a 35×12.5r22 tire equals a 317/52R558 tire in the metric system.
Practical Applications
Understanding tire sizes and their conversions is incredibly practical. For instance, the 35×12.5r22 tire is prevalent among large trucks and SUVs, valued for its increased traction and superior handling on rough terrains.
Imagine you’re an adventurer who loves off-road escapades. Knowing the specifics of your tire size, such as the 35×12.5r22, helps you assess the capabilities of your vehicle.
Its wide width ensures stability, and the large diameter facilitates smooth rides over obstacles, letting you easily conquer rocky landscapes.
What Is Equivalent To A 35×12.5r22?
The tire dimension expressed as 35×12.5r22 can be roughly transposed into metric system notation as 318/52r22, though it’s worth noting that this specific size is rarely seen in commercial outlets.
A more frequently seen metric dimension, and the nearest equivalent, is 315/50r22. This size closely mirrors the features of a 35×12.5r22 tire and is more readily available for consumers to buy.
How Tall Are 35×12.5r22 Tire Size?
The “35” in the tire size refers to its diameter in inches. Therefore, a tire of this size is 35 inches tall.
How Wide Is A 35×12.5r22 Tire?
The “12.5” in the tire size denotes the width. Consequently, a tire of this size is 12.5 inches wide.
What Size Rim Fits 35×12.5r22?
The “22” in the tire size stands for the diameter of the wheel, or the rim size, in inches. This means that a 35×12.5r22 tire would be compatible with a 22-inch rim.
Summary
In exploring the 35×12.5r22 tire size, we’ve delved into the anatomy of tire dimensions, demystified the conversion process from inches to millimeters, and discovered practical, real-world applications of this knowledge.
Understanding tire sizes equips you with essential information about your vehicle’s capabilities and limitations, empowering you to make informed decisions on and off the road. Armed with this knowledge, you are better prepared to tackle the adventures that await you behind the wheel.
