Tire Size Breakdown
Lets break down the tire size 265/75R16 into inches:

  • 265: This refers to the width of the tire tread in millimeters.
  • 75: This is the aspect ratio of the tire, which represents the height of the sidewall as a percentage of the tire’s width. In this case, the sidewall height is 75% of the tire’s width.
  • R: This indicates that the tire has a radial construction.
  • 16: This is the diameter of the wheel rim, measured in inches, on which the tire is designed to be mounted.

265/75R16 Alternative Size
To ensure proper functionality, the replacement tires must have an overall diameter that is no more than 3% different from the original tire.

Tire Size Overall Diameter Difference
235/80R16 30.8″ (782 mm) -2.7%
345/55R16 30.9″ (786 mm) -2.2%
225/85R16 31″ (788 mm) -2%
295/65R16 31.1″ (790 mm) -1.7%
275/70R16 31.2″ (792 mm) -1.5%
285/70R16 31.7″ (806 mm) 0.2%
235/85R16 31.7″ (806 mm) 0.2%
225/90R16 32″ (812 mm) 1%
375/55R16 32.2″ (818 mm) 1.7%

Overall Diameter
The overall diameter of a 265/75R16 tire, also known as tire height, refers to the total height of the tire from its tread to the bottom of the tire touching the ground. In this case, the overall diameter is 804 millimeters or 31.7 inches.

This measurement is crucial when determining the tire’s compatibility with your vehicle’s wheel well and suspension system, as it can affect ground clearance, turning radius, and even the accuracy of your speedometer.

Tread Width
The tread width of a 265/75R16 tire refers to the width of the tire’s contact patch or the portion of the tire that comes into contact with the road. For this tire size, the tread width measures 265 millimeters or 10.4 inches.

This specification is essential for understanding the tire’s ability to distribute vehicle weight, provide traction, and dissipate heat. A wider tread width typically offers better traction and handling but can also negatively impact fuel efficiency and generate more road noise.

Rim Diameter
The rim diameter is the size of the wheel on which the tire is mounted, measured in inches or millimeters. For a 265/75R16 tire, the rim diameter is 406.4 millimeters or 16 inches.

Matching your tire size to the appropriate wheel size is vital for proper fit and performance. Using an incorrect rim diameter tire can lead to poor handling, decreased fuel efficiency, and even tire failure.

Sidewall Height
The sidewall height of a 265/75R16 tire refers to the vertical distance between the outer edge of the tire’s tread and the top of the wheel’s rim. In this case, the sidewall height measures 199 millimeters or 7.8 inches.

This specification is important for several reasons: ride comfort, handling, and load-carrying capacity. A taller sidewall typically provides a smoother, more comfortable ride but can result in less precise handling, especially when cornering at high speeds.

The circumference of a 265/75R16 tire is the distance around the outer edge of the tire. This measurement is 2524.6 millimeters or 99.5 inches. The tire’s circumference is a critical factor in determining its revolutions per mile or kilometer and calculating the vehicle’s speed and distance traveled.

Revolutions per Mile
Revolutions per mile or kilometer refer to the number of times a tire rotates around its axis while traveling a set distance. For a 265/75R16 tire, it makes 396 revolutions per kilometer or 637 revolutions per mile.

This information is essential for calibrating your vehicle’s speedometer and odometer accurately, as well as assessing the tire’s wear rate and fuel efficiency.

Tire Construction
The letter ‘R’ in the tire size indicates the tire’s construction. In this case, ‘R’ stands for radial construction, which means the tire’s internal ply cords are arranged in a radial direction perpendicular to the tire’s centerline. Radial construction provides better ride comfort, handling, and fuel efficiency than bias-ply tires.

The 265/75R16 tire size balances traction, handling, and ride comfort, making it a popular choice for light trucks, SUVs, and off-road vehicles. Its 10.4-inch tread width provides a substantial contact patch for improved traction and stability.

While its 7.8-inch sidewall height offers a comfortable ride with some added cushioning for off-road applications. The 16-inch rim diameter is standard for light trucks and SUVs, allowing for a wide range of compatible wheel options.
