Overall Diameter
The overall diameter of a tire is the distance from one point on the tire’s tread to the exact opposite point on the tread through the center of the tire. The 265 75r17 tire has an overall diameter of 32.65 inches, while the 265 70r17 tire has a slightly smaller diameter of 31.61 inches.
This means the 265 75r17 tire is one inch taller than the 265 70r17 tire. A larger diameter can provide better ground clearance and increased traction, but it can also affect the vehicle’s speedometer calibration and fuel economy.
Tread Width
The tread width is the width of the tire’s tread or the part of the tire that comes into contact with the road. The 265 75r17 tire has a tread width of 10.43 inches, while the 265 70r17 tire has the same tread width of 10.43 inches.
Rim Diameter
The rim diameter is the diameter of the wheel that the tire is mounted on. The 265 75r17 and 265 70r17 tires are designed to be mounted on 17-inch rims, so there is no difference between the two in this category.
Sidewall Height
The sidewall height is the distance between the wheel rim and the outside edge of the tire. The 265 75r17 tire has a sidewall height of 7.82 inches, while the 265 70r17 tire has a slightly smaller sidewall height of 7.3 inches. A taller sidewall can provide a more comfortable ride and better protection against potholes and other road hazards, but it can also decrease handling and increase the risk of rollovers.
Circumference
The circumference of a tire is the distance around the tire’s outer edge. The 265 75r17 tire has a circumference of 102.57 inches, while the 265 70r17 tire has a slightly smaller circumference of 99.29 inches.
A larger circumference can provide better acceleration and increased top speed, but it can also affect the vehicle’s speedometer calibration and fuel economy.
Revolutions
The number of revolutions a tire makes in one mile can affect the accuracy of the vehicle’s speedometer. The 265 75r17 tire makes 617.71 revolutions per mile, while the 265 70r17 tire makes 638.1 revolutions per mile. This means that the 265 70r17 tire will have a slightly more accurate speedometer reading than the 265 75r17 tire.
Our Observation
In our observation, the 265 75r17 tire size is a good choice for drivers who want a taller tire for increased ground clearance and off-road capability. However, it may negatively affect fuel economy and speedometer calibration.
On the other hand, the 265 70r17 tire size is a good choice for drivers who prioritize better handling and fuel economy, as well as a more accurate speedometer reading. It may also provide a smoother and more comfortable ride due to its smaller sidewall height. Ultimately, choosing these two tire sizes depends on your driving needs and priorities.
