📌 How to Read Tire Sizes: A Quick Guide to Choosing the Right One:
Tire size is typically displayed on the sidewall of a tire in a standard format such as P225/50R17 94V. Here's how to decode it:
1. Tire Type:
The first letter indicates the tire type.
---> P: Passenger vehicle tire.
---> LT: Light truck tire.
---> If no letter is present, it's likely a European metric tire.
2. Tire Width:
The three-digit number (e.g., 225) specifies the width of the tire in millimeters from sidewall to sidewall.
3. Aspect Ratio:
The two-digit number after the slash (e.g., 50) is the aspect ratio. It represents the height of the tire's sidewall as a percentage of the width. In this example, the sidewall height is 50% of 225 mm, or 112.5 mm.
4. Construction Type:
The letter following the aspect ratio (e.g., R) denotes the tire’s internal construction.
---> R: Radial (most common).
---> D: Diagonal or bias-ply.
---> B: Belted bias.
5. Wheel Diameter:
The two-digit number after the construction type (e.g., 17) specifies the wheel diameter in inches that the tire fits.
6. Load Index:
The number after the wheel diameter (e.g., 94) indicates the tire’s load-carrying capacity. Higher numbers mean greater load capacity. You can reference a load index chart to find the exact weight.
7. Speed Rating:
The letter (e.g., V) indicates the maximum speed capability of the tire. For example, V corresponds to 149 mph (240 km/h).
By understanding these markings, you can select the right tires for your vehicle, ensuring safety, performance, and compatibility. Always consult your vehicle's manual for the recommended tire size.
