Tire Size Breakdown
The 265/70r17 tire size can be broken down into three main components:

  1. 265: This represents the tire’s tread width in millimeters (mm). In this case, the tread width is 265 mm, which is approximately 10.4 inches.
  2. 70: This aspect ratio represents the sidewall height as a percentage of the tread width. The sidewall height is 70% of the tread width in this case.
  3. R17: This indicates the tire’s construction type and wheel diameter in inches. The “R” stands for radial construction, and the “17” signifies that the tire is designed to fit a 17-inch wheel.

Alternative Tire Size (265/70r17)
As a general guideline, it’s recommended to choose replacement tires with a diameter measurement that’s no more than 3% different from your current tires.

Tire Size Overall Diameter Difference
235/75R17 30.9″ (784 mm) -2.5%
255/70R17 31.1″ (790 mm) -1.7%
275/65R17 31.1″ (790 mm) -1.7%
305/60R17 31.4″ (798 mm) -0.7%
245/75R17 31.5″ (800 mm) -0.5%
285/65R17 31.6″ (802 mm) -0.2%
235/80R17 31.8″ (808 mm) 0.5%
345/55R17 32″ (812 mm) 1%
255/75R17 32″ (814 mm) 1.2%
275/70R17 32.2″ (818 mm) 1.7%
305/65R17 32.6″ (828 mm) 3%

Overall Diameter
The overall diameter of the 265/70r17 tire is 804 mm, which is approximately 31.7 inches. This measurement is crucial for ensuring proper clearance between the tire and the vehicle’s body, as well as for determining the correct speedometer and odometer readings.

Tread Width
The tread width of the 265/70r17 tire is 265 mm or about 10.4 inches. This width impacts the tire’s contact patch, which is the area of the tire that makes contact with the road surface. A wider tread width can offer better traction and stability, especially in off-road or wet conditions.

Rim Diameter
The 265/70r17 tire is designed to fit a 17-inch wheel with a rim diameter of 431.8 mm. This wheel size is a popular choice for light trucks and SUVs, offering a balance between ride comfort and handling performance.

Sidewall Height
The sidewall height of the 265/70r17 tire is 186 mm or approximately 7.3 inches. This measurement is calculated by multiplying the tread width (265 mm) by the aspect ratio (70%) and represents the distance between the tire’s bead and its outer edge.

A taller sidewall height can improve ride comfort and off-road performance, while a shorter sidewall height can enhance handling and cornering stability.

The circumference of the 265/70r17 tire is 2524.6 mm or about 99.5 inches. This measurement is essential for determining the tire’s revolutions per mile, which impacts the vehicle’s speedometer and odometer readings.

The 265/70r17 tire makes 396 revolutions per kilometer or approximately 637 revolutions per mile. This number is calculated by dividing the tire’s circumference by its overall diameter. Understanding the revolutions per mile ensures accurate speedometer and odometer readings.

Tire Construction
The 265/70r17 tire features radial construction, as indicated by the “R” in the tire size. Radial construction involves arranging the tire’s cords at a 90-degree angle to the direction of travel, resulting in a more flexible sidewall and improved ride comfort. Radial tires also offer better fuel efficiency, longer tread life, and enhanced traction compared to bias-ply tires.

Our Observation
Due to its balanced dimensions and performance attributes, the 265/70r17 tire size is a versatile and popular choice for light trucks and SUVs. With a tread width of 10.4 inches and an overall diameter of 31.7 inches, these tires offer a substantial contact patch for improved traction and stability in various driving conditions.

The 7.3-inch sidewall height provides a comfortable ride and enhances off-road capabilities, while the 17-inch wheel size maintains a balance between ride comfort and handling performance. Radial construction further improves the tire’s ride comfort, fuel efficiency, and tread life, making the 265/70R17 tire an excellent option for drivers seeking a well-rounded tire for their vehicle. 

In summary, the 265/70r17 tire size offers a great combination of dimensions and performance characteristics, making it a popular choice for those looking to equip their light trucks or SUVs with reliable and efficient tires.
