Finding Your Tire Size Made Easy

Step 1: Locate Your Tire Size

Understanding your vehicle’s tire size is the first step toward ensuring you select the right tires for optimal performance. Here are three reliable methods to find this information:

• Vehicle’s Owner’s Manual: The most straightforward source for your tire size is the owner’s manual of your vehicle, where the manufacturer lists the recommended tire size.
• Tire Sidewall: Inspect the sidewall of your tire for a series of numbers and letters (e.g., 225/50R17), indicating your tire’s specifications.
• Driver Door/Door Jamb Sticker: Often overlooked, this sticker provides vital tire information, including the recommended tire size and inflation pressures.

Understanding Your Tire Size

Each element of the tire size notation provides valuable information about the tire’s dimensions and characteristics:

• Width in Millimeters (e.g., 225): This number indicates the tire’s width from one sidewall to another.
• Aspect Ratio (e.g., 50): This percentage represents the height of the tire’s sidewall relative to its width.
• Construction Type (e.g., R for Radial): This letter describes the tire’s construction, with “R” indicating a radial tire.
• Wheel Diameter in Inches (e.g., 17): This number shows the diameter of the wheel that the tire is intended to fit.

Step 2: Check for Additional Information

Some tires might feature extra markings to denote special capabilities, such as “M+S” for mud and snow, enhancing your driving experience in specific conditions.
