How can I accurately measure bike tires to ensure I am selecting the correct size for my bicycle?

To accurately measure bike tires for your bicycle, use a tape measure to determine the diameter of the tire in inches. This measurement should match the size indicated on the sidewall of the tire. Additionally, check the width of the tire to ensure it fits within the frame of your bike. By measuring both the diameter and width of the tire, you can select the correct size for your bicycle.
