Tire Size Calculator

Tire Size Calculator

Instructions:
 
Enter the tire information found on the sidewall of your tire. For example a tire that is marked 205/65 R16 has a tread width of 205, a profile of 65, and a wheel size of 16". This will give an approximation of your tire diameter and rollout. Due to variations in tire construction and wheel widths this is not an exact number.
 
    
Enter Tread Width:Calculated Diameter (in) IN
Enter Profile:Calculated Diameter (mm) MM
Enter Wheel Diameter: (IN)Calculated Width (in) IN
Enter Wheel Diameter: (MM)Calculated Rollout (in) IN
  Calculated Rollout (mm) MM
