Overall Diameter

The 315/25R23 tire size is characterized by an overall diameter of 29.2 inches, measured from one edge to the other. This measurement reflects the tire’s complete height when filled to the recommended pressure.

Tread Width

The 315/25R23 tire has a tread or section width of 12.4 inches. This dimension represents the distance between one sidewall to the other, signifying the contact area with the road surface.

Tire Circumference

The 315/25R23 tire has a circumference of 91.7 inches, representing the linear distance traveled in a single revolution. This measurement is crucial for determining speed, distance, and revolutions per minute (RPM).

Sidewall Height

The 315/25R23 tires feature a sidewall height of 3.1 inches. This measurement represents the vertical distance from the outer edge of the rim to the outer edge of the tire’s tread.

It plays a crucial role in defining the tire’s profile, impacting both ride comfort and handling attributes.

Revolutions Per Mile

The 315/25R23 tire size completes around 690.7 revolutions per mile. This metric signifies the full rotations the tire makes while covering one mile.

It’s important to grasp this value, as it plays a significant role in odometer readings, speed calculations, and aspects of fuel efficiency.

Wheel Size

The appropriate rim size for 315/25R23 tires is 23 inches in diameter. This detail becomes crucial when contemplating wheel replacement or upgrade, as it guarantees proper fitting of the tire onto the rim.

Construction Type

Finally, the 315/25R23 tires utilize a radial construction. In radial tire design, the internal layers or “plies” are oriented perpendicular to the direction of travel.

This configuration enhances heat dissipation and elevates overall performance, surpassing alternative construction methods.

What Does 315/25R23 Mean?

The term “315/25R23” refers to the size and specifications of a tire. Here’s a breakdown of what each part of the designation means:

  • 315: This number represents the width of the tire in millimeters. In this case, the tire is 315 millimeters wide from sidewall to sidewall.
  • 25: This number indicates the aspect ratio, which is the ratio of the tire’s sidewall height to its width. In this example, the aspect ratio is 25, meaning the sidewall height is 25% of the tire’s width.
  • R: This letter stands for “radial,” which is the most common type of tire construction. Radial tires have ply cords that run perpendicular to the direction of travel.
  • 23: This number represents the diameter of the wheel, in inches, on which the tire is designed to fit.

So, in summary, a tire with the designation 315/25R23 is a radial tire that is 315 millimeters wide, with a sidewall height that is 25% of the width, and it is designed to fit a 23-inch wheel.
