Are P205-55-R16 interchangeable with P215-60-R16

P205/55R16 and P215/60R16 tires are not directly interchangeable due to differences in width and aspect ratio. The first number indicates the tire width in millimeters, so the P215 is wider than the P205. The second number represents the aspect ratio, which is the height of the sidewall as a percentage of the width; a 60 aspect ratio means a taller sidewall compared to a 55. Using different sizes can affect handling, speedometer accuracy, and overall vehicle dynamics, so it's best to consult your vehicle's specifications or a tire professional before making a change.
