svet-max [94.6K]

Answer:

92 inches

Step-by-step explanation:

When a tire's size = P220/65 R 18, it means that:

  • the rim is 18 inches wide (or 457 millimeters)
  • the width of the tire is 8.7 inches (or 220 millimeters)
  • the sidewall of the tire is 5.65 inches (or 144 millimeters)
  • the 65 shows the relationship between tire width and sidewall (65%)

the total diameter of the tire = 5.65 + 18 + 5.65 = 29.3 inches

the circumference = 2 x π x radius   or   diameter x π = 29.3 x 3.141592 = 92 inches
