To find the correct tire size, check the sidewall of your current tires or look at the owner’s manual. The size typically includes a series of numbers, such as 205/55R16, where 205 is the width in millimeters, 55 is the aspect ratio, and 16 is the diameter in inches. If you’re unsure, ask for assistance from a trusted tire shop or mechanic to ensure you get the right size for safety and performance.
