What Does 285 75r17 Tire Mean?

The 285 indicates that this tire has a width of 285 millimeters. The 75 is the sidewall aspect ratio, which means that the tire’s sidewall is 75% as tall as the width. The R, in this instance, stands for radial construction. And finally, the 17 is the wheel diameter or rim size in inches that this tire fits on.

Tire Diameter
One of the main things you want to consider when choosing a tire size is the diameter. This is important because the wrong-size tire can throw off your speedometer and cause problems with your odometer. You also don’t want too small tires because they won’t provide enough traction and could cause you to slip or skid.

The 315 70r17 tire has a diameter of 34.36 inches, while the 285 75r17 tire has a diameter of 33.83 inches. This means that the 315 70r17 is slightly larger in diameter than the 285 75r17.

Section Width
The tread depth is measured in millimeters from the center of one spoke to another. This number is significant since it influences how much contact the tire has with the road. A larger tire will have more contact with the road, providing more excellent traction. However, a wider tire may also imply increased resistance, reducing fuel efficiency.

The 315 70r17 tire has a section width of 12.4 inches, while the 285 75r17 tire has a section width of 11.22 inches. This means that the 315 70r17 is wider than the 285 75r17. The difference in section width is 1.18 inches or 9.5%.

Circumference
The circumference number is important because it affects the revolutions per mile (RPM). A larger circumference tire will have a lower RPM, while a smaller circumference tire will have a higher RPM.

The 315 70r17 tire has a circumference of 107.95 inches, while the 285 75r17 tire has a circumference of 106.28 inches. This means that the 315 70r17 has a larger circumference than the 285 75r17. The difference in circumference is 1.67 inches or 1.5%.

Revolutions Per Mile
As we mentioned before, the revolutions per mile (RPM) are affected by the tire’s circumference. The 315 70r17 has an RPM of 586, while the 285 75r17 has an RPM of 596. This means the 285 75r17 has a lower RPM than the 315 70r17. The difference in RPM is 10 or 1.6%.

Sidewall Height
Another important aspect to consider is the sidewall height. This number tells you how tall the tire’s sidewall is about the width. A taller sidewall usually means a softer ride, while a shorter sidewall usually means better handling.

The 315 70r17 has a sidewall height of 8.68 inches, while the 285 75r17 has a sidewall height of 8.42 inches. This means that the 315 70r17 has a shorter sidewall than the 285 75r17. The difference in sidewall height is 0.27 inches or 3.1%.

Wheel Size
Rim size is essential because you need to ensure the tire will fit on your vehicle. You also want to ensure that the rim size is compatible with the other parts of your vehicle, such as the brakes.

The 315 70r17 has a wheel size of 17 inches, while the 285 75r17 has a wheel size of 17 inches. This means that both tires have the same wheel size.

Construction Type
Radial tires are the most common type of tire construction. This type of tire has steel belts that run radially or perpendicular to the direction of travel. Radial tires are known for their durability, fuel efficiency, and comfort. Both the 315 70r17 and the 285 75r17 have radial construction.

Our Observation
The main difference between 315 70r17 and 285 75r17 Tire Size is in the section width. The 315 70r17 is wider than the 285 75r17 by about an inch. If you are looking for a tire with better traction, then the 315 70r17 would be better. If you are looking for a tire with lower resistance and improved fuel efficiency, then the 285 75r17 would be a better choice.

Conclusion
The 315 70r17 and 285 75r17 are both radial tires with the same wheel size. The main difference between these two tires is the section width. We hope you found this blog post helpful. If you have any questions, please feel free to contact us. Thank you for reading!
