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.

Overall Diameter

The Tire Height of the 265/75r16 tire size is approximately 31.7 inches or 804 millimeters. This measurement, also known as the overall diameter, is derived by doubling the sidewall height and then adding the rim diameter. This dimension is crucial as it affects the vehicle’s speedometer, odometer, and clearance.

Tread Width

Tread Width of 265 75R16 Tire Size

The 265/75r16 tire’s tread width is around 10.4 inches or 265 millimeters. Tread width is the width of the tire’s tread (the part that comes into contact with the road surface).

It is essential for handling and traction on different surfaces, contributing to the vehicle’s performance and safety.

Rim Diameter

For the 265/75r16 tire size, the rim diameter is 16 inches or 406.4 millimeters. The rim size indicates the diameter of the wheel on which the tire is mounted.

Passenger tires can be mounted on wheels that are 7-9 inches wide, while LT tires can be mounted on wheels that are 7-8 inches wide. A proper fit between the tire and the wheel is crucial to the tire’s performance and the vehicle’s safety.

Sidewall Height

The 265/75r16 tire’s sidewall height is about 7.8 inches or 199 mm. The sidewall is the portion of the tire between the tread and the rim. The larger sidewall height contributes to a smoother ride as it absorbs more shocks from the road, but it might compromise handling and steering precision.


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.
