Overall Diameter
The overall diameter of a tire is the distance between the tire’s outer edges when mounted and inflated. The overall diameter of a tire affects various aspects of the vehicle, including speedometer accuracy, acceleration, and fuel economy.
The overall diameter of a 275/65R17 tire is 31.07 inches, while that of a 265/70R17 is 31.61 inches. This means that the 265/70R17 is slightly larger in size and will provide a higher ground clearance.
Tread Width
The tread width is the width of the tire’s contact surface with the ground. It affects the vehicle’s handling, traction, and stability. The tread width of a 275/65R17 tire is 10.83 inches, while that of a 265/70R17 tire is 10.43 inches. This means that the 275/65R17 tire will have a wider contact surface with the ground, which will provide better stability and handling.
Rim Diameter
The rim diameter is the diameter of the wheel that the tire fits onto. It is essential to choose the correct rim diameter for the tire to ensure a proper fit. Both 275/65R17 and 265/70R17 tires have a rim diameter of 17 inches.
Sidewall Height
The sidewall height is the distance between the rim and the outer edge of the tire. It affects the vehicle’s ride comfort and handling. The sidewall height of a 275/65R17 tire is 7.04 inches, while that of a 265/70R17 tire is 7.3 inches.
This means that the 265/70R17 tire will have a taller sidewall, which will provide a more comfortable ride and better protection against potholes and other road hazards.
Circumference & Revolutions
The circumference and revolutions of a tire are crucial factors that affect the accuracy of the vehicle’s speedometer. The circumference of a 275/65R17 tire is 97.62 inches, while that of a 265/70R17 tire is 99.29 inches.
This means that the 265/70R17 tire will cover more ground with each revolution and cause the speedometer to read slightly lower than the actual speed.
