Overall Diameter

  • Overall diameter is shown as the first number in the floatation tire size.
  • You can get the overall diameter of a tire by measuring the distance across the tire’s outermost circumference.
  • The larger the tire’s diameter, the more it can stabilize the car.
  • This dimension of the tire determines the ability of a tire to ride on different road conditions.
  • The larger overall diameter contributes to the improvements in traction.
  • The smaller overall diameter shows improved diameter readings.

The 265 70r17 tire has a larger overall diameter of 31.61 inches, and the 245 70r17 tire has a smaller overall diameter of 30.5 inches. Though the difference is insignificant, it can affect how the vehicle can handle different road conditions.


  • The lighter a tire is, the better the choice for performance vehicles.

  • The section width refers to the width of your tire from sidewall to sidewall.
  • Width is the first number of the tire size information.

While the 245 70r17 tire’s width is 10.43 inches, the 265 70r17 tire’s width is 9.65 inches. So, the former has 0.78 more widths than the latter one, which helps the wider one offer better traction and create more drag on the car.

Revolutions Per Mile

  • Revelation per mile of a tire refers to how many times the tire can go around in a mile.
  • The tire with higher revolutions per mile can cover more ground within a specific time.
  • The lower revolutions per mile don’t allow a tire to cover more ground.

While the 245 70r17 tire has about 638 revolutions per mile, the 265 70r17 tire has 661 revolutions per mile. So, the difference of 23 miles affects the speed rate of the vehicles. 245 70r17 can’t cover as much ground as 265 70r17.


  • To get a tire’s circumference, multiply the diameter measurement by pi.
  • The larger circumference helps the tire cover more ground per revolution.
