Overall Diameter

The 345/30R19 tire size is characterized by an overall diameter of 27.1 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 345/30R19 tire has a tread or section width of 13.6 inches. This dimension represents the distance between one sidewall to the other, signifying the contact area with the road surface.

Tire Circumference

The 345/30R19 tire has a circumference of 85.3 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 345/30R19 tires feature a sidewall height of 4.1 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 345/30R19 tire size completes around 742.9 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 345/30R19 tires is 19 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 345/30R19 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 345/30R19 Mean?

The term “345/30R19” refers to the size and specifications of a tire. Here’s a breakdown of what each part of the designation means:

  • 345: This number represents the width of the tire in millimeters. In this case, the tire is 345 millimeters wide from sidewall to sidewall.
  • 30: 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 30, meaning the sidewall height is 30% 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.
  • 19: 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 345/30R19 is a radial tire that is 345 millimeters wide, with a sidewall height that is 30% of the width, and it is designed to fit a 19-inch wheel.

What Is 345/30R19 In Inches?

The tire size 345/30R19 can be expressed in inches as approximately 13.6 inches wide, 4.1 inches tall in sidewall, and designed to fit a 19-inch wheel rim. The 345/30R19 also has a circumference of 85.3 inches and It completes 742.9 revolutions per mile.

345/30R19 Equivalent

The tire size 345/30R19 is equivalent with a size of 27.1x13.6R19 in inches. This correlation is pivotal for precision in tire selection and optimal vehicle performance.

How Tall Is A 345/30R19 Tire?

The height of a 345/30R19 tire, expressed through its diameter, is approximately 27.1 inches (689.6 mm). In short, A 345/30R19 tire size is 27.1 inches (689.6 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 345/30R19 Tire?

The width of a 345/30R19 tire is 13.6 inches (345 millimeters). The first number in the tire size (345) represents the tire’s nominal width in millimeters from sidewall to sidewall when mounted on a specified width wheel. Therefore, the 345/30R19 tire size is 13.6 inches (345 mm) wide.

What Size Rim For 345/30R19?

The size of the rim for a 345/30R19 tire is 19 inches in wheel diameter. In the tire size 345/30R19, the number “19” at the end indicates the diameter of the wheel (rim) in inches that the tire is designed to fit.

Replacement Tire Sizes

New tires must match the original tire’s overall diameter within a 3% range. The rim width range for this tire is typically 11.5-12.5″.
