Overall Diameter

The 145/80R16 tire size is characterized by an overall diameter of 25.1 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 145/80R16 tire has a tread or section width of 5.7 inches. This dimension represents the distance between one sidewall to the other, signifying the contact area with the road surface.

Tire Circumference

The 145/80R16 tire has a circumference of 79 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 145/80R16 tires feature a sidewall height of 4.6 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 145/80R16 tire size completes around 802.4 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 145/80R16 tires is 16 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 145/80R16 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 145/80R16 Mean?

The term “145/80R16” refers to the size and specifications of a tire. Here’s a breakdown of what each part of the designation means:

  • 145: This number represents the width of the tire in millimeters. In this case, the tire is 145 millimeters wide from sidewall to sidewall.
  • 80: 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 80, meaning the sidewall height is 80% 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.
  • 16: 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 145/80R16 is a radial tire that is 145 millimeters wide, with a sidewall height that is 80% of the width, and it is designed to fit a 16-inch wheel.

What Is 145/80R16 In Inches?

The tire size 145/80R16 can be expressed in inches as approximately 5.7 inches wide, 4.6 inches tall in sidewall, and designed to fit a 16-inch wheel rim. The 145/80R16 also has a circumference of 79 inches and It completes 802.4 revolutions per mile.

145/80R16 Equivalent

The tire size 145/80R16 is equivalent with a size of 25.1x5.7R16 in inches. This correlation is pivotal for precision in tire selection and optimal vehicle performance.

How Tall Is A 145/80R16 Tire?

The height of a 145/80R16 tire, expressed through its diameter, is approximately 25.1 inches (638.4 mm). In short, A 145/80R16 tire size is 25.1 inches (638.4 mm) tall.

The height of the tire is subject to slight variations, determined by both the brand and model of the tire, in addition to the amount of air pressure it holds.

How Wide Is A 145/80R16 Tire?

The width of a 145/80R16 tire is 5.7 inches (145 millimeters). The first number in the tire size (145) represents the tire’s nominal width in millimeters from sidewall to sidewall when mounted on a specified width wheel. Therefore, the 145/80R16 tire size is 5.7 inches (145 mm) wide.

What Size Rim For 145/80R16?

The size of the rim for a 145/80R16 tire is 16 inches in wheel diameter. In the tire size 145/80R16, the number “16” at the end indicates the diameter of the wheel (rim) in inches that the tire is designed to fit.
