Overall Diameter
The tire’s overall diameter affects the speedometer reading, the ride height, and the vehicle’s ground clearance. The 255 85r16 tire has a larger overall diameter of 33.1 inches, while the 265 75r16 has a diameter of 31.7 inches.

This means that the 255 85r16 tire will give your vehicle a slightly higher ride height and more ground clearance. On the other hand, the 265 75r16 tire will provide a more accurate speedometer reading.

Tread Width
The tread width of a tire is the measurement from one sidewall to the other, including the tread. The 265 75r16 has a tread width of 8.5 inches, while the 255 85r16 has a slightly wider tread width of 9.8 inches.

This means that the 255 85r16 tire will have a slightly larger contact patch with the road, which can provide better traction and stability. However, a wider tire may also be more prone to hydroplaning in wet conditions.

Rim Diameter
The rim diameter is the measurement of the wheel from one end to the other. The 265 75r16 tire is designed to fit on a 16-inch rim, while the 255 85r16 tire is designed for a 16-inch rim. This means that the 265 75r16 tire will fit on various wheels. At the same time, the 255 85r16 is more limited in its compatibility.

Sidewall Height
The sidewall height of a tire is the measurement from the edge of the rim to the top of the tread. The 255 85r16 tire has a taller sidewall height of 7.9 inches, while the 265 75r16 has a sidewall height of 7.0 inches. A taller sidewall height can provide more cushioning and absorb more shocks and bumps, but it may also result in more body roll and a less responsive feel.

The circumference and revolutions of a tire are closely related to the overall diameter. The 255 85r16 tire has a circumference of 104 inches and completes 613 revolutions per mile, while the 265 75r16 tire has a circumference of 99.6 inches and completes 646 revolutions per mile. This means that the 255 85r16 tire will travel a slightly longer distance with each rotation, resulting in a lower engine RPM at a given speed.

Our Observation
Overall, the choice between the 265 75r16 and the 255 85r16 tire will come down to your specific needs and preferences. If you prioritize off-road performance and ground clearance, the 255 85r16 may be the better choice. However, the 265 75r16 may be a better fit if you prioritize on-road performance and speedometer accuracy.

It’s important to remember that changing the size of your tires can affect your vehicle’s performance, so it’s a good idea to consult with a professional mechanic or tire specialist before making a final decision. By comparing overall diameter, tread width, rim diameter, sidewall height, circumference, revolutions, and alternative sizes, you can determine which tire will work best for your vehicle and driving style.
