Understanding Tire Size Numbers and What They Mean
We decode tire size markings to help 06 Chevy Impala owners make informed replacement decisions. Each number and letter combination on your tire sidewall provides exact information about dimensions, construction, and performance capabilities.
Breaking Down the Tire Size Code
Reading the P225/60R16 tire size found on most 06 Chevy Impala models reveals critical specifications through each segment. The “P” designation indicates passenger vehicle construction standards set by the Tire and Rim Association. Our breakdown of “225” shows the tire width measured in millimeters from sidewall to sidewall when mounted on the recommended rim width.
Following the width measurement, “60” represents the aspect ratio calculated as sidewall height divided by tire width and expressed as a percentage. Lower aspect ratios like the 50 found on SS models create shorter sidewalls that improve handling response. The “R” indicates radial construction where internal plies run perpendicular to the direction of travel.
Final digits “16” specify the wheel diameter in inches that matches your Impala’s rim size. Matching this diameter ensures proper fitment with your existing wheels. Different diameter sizes require corresponding wheel changes to maintain proper vehicle operation.
