How to Read Tire Size for PCR Tires
When choosing the right tires for your passenger car, understanding how to read the tire size is essential. Passenger Car Radial (PCR) tires are designed for vehicles such as sedans, SUVs, and light trucks. The size of the tire, printed on the tire’s sidewall, gives valuable information about its width, height, and compatibility with your vehicle.
Here’s how to decode a typical PCR tire size: 225/50R17 91V.
Decoding PCR Tire Size:
- 225: The first number represents the tire’s width in millimeters from sidewall to sidewall. In this case, the tire is 225 mm wide.
- 50: The second number is the aspect ratio, which is the height of the tire’s sidewall as a percentage of its width. Here, the sidewall height is 50% of the tire’s width.
- R: The “R” indicates radial construction, which is the standard for most modern tires.
- 17: This number shows the diameter of the wheel rim in inches. In this case, the tire is designed for a 17-inch rim.
- 91: This is the load index, indicating how much weight the tire can safely carry. A load index of 91 means the tire can support 615 kg.
- V: The speed rating signifies the maximum speed the tire can safely sustain. A “V” rating means the tire is rated for speeds up to 240 km/h.
